      Similar to other deposits of this type in the world, three major stages could be considered for mineralization in Mari copper deposit. The Mari Copper deposit is located in the northwest of Iran and Tarom metallogenic zone in the north of Zanjan. The ore-body is strata-bound and hosted by the Eocene mega-porphyritic andesites. The major copper sulfides are bornite, chalcocite, and chalcopyrite associated mainly with pyrite that represent open-space filling, disseminated, vein-veinlet, and replacement textures. The volcanic rocks of the study area mostly represent intermediate to acidic composition with high potassium shoshonitic magmatic series related to intra-arc rift environments. Wall rock alterations include carbonatization, chloritization, epidotization, and sericitization. The abundances of Cu and Ag in fresh mega-porphyritic andesite are up to 3200 and 216 ppm respectively. Based on the main characteristics of Mari ore body such as tectonic setting, host rock, strata-bound form, mineralogy, metal content, and wall rock alterations and comparison of these features with Manto - type copper deposits, Mari Cu deposit can be introduced as a Manto -type Cu deposit in NW Iran. The first stage includes submarine volcanic activity and eruption of mega-porphyritic andesitic lava associated with regional propylitic alteration. In the second stage, the early diagenesis and the activity of sulfate-reducing micro-organisms resulted in the generation of pyrite in the form of open-space filling and disseminated in the mega-porphyritic andesite. Finally, in the third stage, increasing of the thickness of sediments, basin subsidence, and burial diagenesis accompanied with the entry of metal-rich fluids into the reduced host rock, caused the replacement of the first stage pyrites by copper sulfides and mineralization in the Mari deposit.

      The study area is geologically located in the northern area of the Sanandaj-Sirjan metamorphic zone. Based on petrographic study, the main minerals consists of plagioclase, pyroxene, amphibole and biotite and the accessory minerals are chlorite, muscovite, ilmenite and zircon. The obtained results from the mineral chemistry in this study indicate that the amphiboles are calcic amphiboles, and in terms of chemical composition they can be called pargasit, tschermakite and magnesiohomblende. Plagioclases are also andesian. Due to the low Na2O content, it can be concluded, that tectonically these amphiboles are of S-Amph type and are related to the subduction zones. Based on the high levels of Al2O3, the origin of amphiboles is mantle-type. Therefore, due to the ratio of Fetot (Fetot + Mg+2) to AlIv, which is less than 0.6, the oxygen fugacity was high. On the other hand, the water levels vary from 2 to 2.3 for hornblende crystallization. Different methods were used to perform thermobarometry, the best of which showed that the formation temperature of gabbroic mass has been in the range of 700°C (in average) and a pressure of 4.45- 7.52 Kb. According to the estimated pressures, the magma was originated at a depth of 25-30 Km, which is near the Moho discontinuity. Manuscript Document

      Construction of new cities or development of old towns in an area requires geological and geophysical (seismic) studies. The city of Khoy is one of the developing cities that have to be study. Therefore, the Deterministic and Probabilistic Seismic Hazard Analysis (DSHA and PSHA) approaches have been used to assess seismic hazards and earthquake risk in the city. For this purpose, analyses have been carried out considering historic and instrumented earthquakes, geologic and seismotectonic parameters of the region covering a radius of 100 km with the city of Khoy in the center. Therefore, the main faults and fault zones in the study area were studied and length and distance of each fault from the center of the city of Khoy was calculated. At the next step, the Maximum Credible Earthquake (MCE) and Peak Ground Acceleration (PGA) have been measured using both DSHA and PSHA approaches and also equations presented by different researchers. DSHA Results show that the MCE and PGA values are 6.5 and 0.31g, respectively. PSHA results indicated that the MCE evaluated value is 6.1 for a 0.64 probability in a 50-years period. The period of this earthquake is 110 years and its probability will be 0.009 per a year. The occurrence probability of earthquakes with magnitude equal or greater than 7.1 is 10% and for earthquakes with magnitude equal or greater than 6.3 is 50% for the study area. Manuscript Document

      In this study, the optimized DRASTIC model parameters and land use layer (LU) were used to assess specific vulnerability in Kashan aquifer using statistical methods. Information layers were prepared, rated (deterministic and fuzzy-statistical), weighted (original and statistical) and combined (by Index-Overlay method) in GIS environment. For optimization of DRASTIC model, nonlinear regression for fuzzy-statistical rating (scaling) and Pearson correlation coefficients between nitrate concentrations and scaling parameters of DRASTIC model and sensitivity analysis (removal and single-parameter) were performed to determine and modify weighted parameters. As a result, RASIC-LU model with statistical rating and weighting, single-parameter sensitivity analysis, determined the best selection model based on correlation coefficient = 61.1%, P-Value= 0.001 and with parameters of net recharge, aquifer media, soil media, impact of vadose zone, hydraulic conductivity and land use with weight values of 2.50, 4.63, 4.15, 3.03, 1.96 and 2.00 respectively. According to this model, western and southern parts of the aquifer has a high and very high pollution risk due to high net recharge, pollutant land use and coarse-grain material in the impact of vadose zone, soil and aquifer media. In addition, sensitivity analysis based on mean squares error (MSE) indicated that this model is more sensitive to removal and increase of parameters weight of land use, soil media, impact of vadose zone, aquifer media, net recharge and hydraulic conductivity, and shows a decreasing ternd, respectivily.

      In this paper, Multi-Layer Perceptron (MLP) and Radial Basis Function (RBF) Artificial Neural Networks (ANNs) are designed for the determination of confined aquifer parameters: transmissibility and storage coefficient. The networks are trained for the well function of confined aquifers. By applying the principal component analysis (PCA) on the training data sets the topology of the MLP and RBF networks is reduced and fixed to [1×12×1] and [1×14×1], respectively regardless of number of records in the pumping test data. The networks generate the optimal match point coordinates for any individual real pumping test data set. The match point coordinates are then incorporated with Theis analytical solution (1935) and the aquifer parameter values are determined. The generalization ability and performance of the developed networks is evaluated with 100000 sets of synthetic data and their accuracy is compared with that of type curve matching technique by two sets of real pumping test data. The results showed that though both MLP and RBF networks are able to determine the confined aquifers parameters and eliminate graphical error inherent in the type curve matching technique but the MLP network is more accurate than the RBF network. Therefore, the proposed MLP network is recommended as an accurate automatic and fast procedure for the confined aquifer parameters estimation. Manuscript Document

      Since the measured well drawdowns in a single well test does not reflect the aquifer head loss and covering linear and nonlinear well losses, the calculations based on the observed head loss from a pumping well, cannot get a precise estimate of the hydrodynamic parameters of the aquifer. But when an inexpensive and rapid estimation of aquifer transmissivity is required, using the collected data from a single pumping well is amongst the attractive options. Several methods for estimating borehole loss components has been proposed by various researchers. In this study, methods proposed by Eden-Hazel, Hantush-Biershenk, Kasinow, Miller-Weber and Karami-Younger; suggesting to calculate well loss component (CQn) were assessed to determine the transmissivity of the aquifer using measured head losses from both the pumping well and the adjacent piezometer from some aquifer tests conducted on a number of exploration wells of Khorasan (Razavi and Southern) provinces. The calculated well loss components using Eden-Hazel, Hantush-Biershenk, Kasenow and Miller-Weber methods has a significant difference to the simulated well losses using piezometric data. Karami-Younger method has been able to calculate the CQn value more accurately, about 25% to the simulated value. However, an accurate CQn estimate did not necessarily concluded to an acceptable aquifer transmissivity calculation. In the other words, the results of implementation of this method is more sensitive in sediments with high permeability and lower well losses. Manuscript Document

      The Kuh-Gabbri granitoid is located at 42 Km east of Rafsanjan in Kerman provinc. This region is small part of Urumieh- Dokhtar magmatic belt of Iran. Intrusive of two granitoid stocks into upper Crataceous limestone and lower Paleocene polygenetic conglomerate, produced contact metamorphism. These rocks contain major minerals such as Quartz, Alkali feldspar and Plagioclase; minor minerals as Biotite, Zircon and Opaque. The SiO2 contents range from 75.57 to 76.83 wt%. The majority of the Kuh-e- Gabbri rocks show similar patterns in the trace element plot normalized to primitive mantle and condrite. These rocks are generally enriched in Rb and Th, and depleted in Ba, Sr and Eu. Condrite- normalized REE patterns are moderately LREE enriched white pronounced negative Eu anomalies. The Nb anomaly implies a crustal component. Moreover all data belong to the within- plate granite fild in the tectonic discrimination diagram and those are I- type granite. Felid, petro raphic and geochemical characteristics suggest magmatic origin and crustal source rock under low pressure conditions. Petro raphic and chemical variations were mainly the result of fractional crystallization. Manuscript Document

      The Qolqoleh gold deposit is located in the northwestern part of the Sanandaj–Sirjan metamorphic belt, about 50 km south-west of Saqqez. The rocks in the vicinity of the Qolqoleh deposit consist predominantly of Mesozoic volcano-sedimentary sequences of phyllite, meta-limestone, cholorite- sericite schist, metavolcanic and granitic intrusive rocks that have undergone greenschist facies metamorphism. Geochemical studies indicate that gold mineralization occur in the sulfide-quartz veins. Based on the number of phases present at room temperature and their microthermometric behavior, three fluid inclusion types were recognized: type I mono phase aqueous inclusions, type II two-phase aqueous inclusions (aqueous + vapor), that based on Th could be subdivided into two groups: type IIa show salinities of 5–13 wt.% NaCl equivalent and Th-tot of 205 to 255 °C. Type IIb with salinities of 15–19 wt.% NaCl equivalent and Th-tot of 335 to 385 C. Type III three-phase shows carbonic–aqueous inclusions (aqueous–LCO2–VCO2) with salinities of 9–13 wt.% NaCl equivalent and Th-tot of 345–385 °C. Furthermore, the mean values of density of ore-forming fluids, pressure and depth of mineralization are 0.79-0.93 gr/cm3, 2 Kbar and 7 Km respectively. On the basis of these data, the Qolqoleh gold deposit is categorized in meso zonal orogenic gold deposit. The δ_0^18 values of the ore-forming fluids are in the range of 7.2‰ to 8‰ and the D values are from -35.27‰ to -40.23‰, which indicate a source of deep-originated metamorphic water that is partially mixed with shallow meteoric water. The change of tectonic regime from compressional to extensional in association with the continuously increasing geothermal gradient, results in remobilization of large amounts of metamorphic fluids. Mixing of ascending orogenic drive fluids with descending meteoric fluids led to deposition of gold by sulfide minerals. Manuscript Document

      Abstract: The Lakhshak Sb index is located in northwest of Zahedan in the Sistan suture zone. The geological units of the area are metamorphosed flysch, granitoid pluton, acidic and basic dikes, mineralized and un-mineralized silicic veins. According to geochemical studies, Lakhshak igneous rocks are calc-alkaline, high-K calc-alkaline and shoshonitic, metaluminous and belong to volcanic arc, and collisional and post-collisional tectonic settings. The study igneous rocks are characterized by LREE and LILE enrichment relative to HREE and HFSE. Enrichment of Pb and depletion of Zr, Nb and Y are more consistent with melts generated from the lower crust. The Sb mineralization in the Lakhshak is an epithermal type that mainly occurs as quartz-stibnite veins in flysch-like rocks and associated with silicic, argillic and phyllic alterations.

      Meyghan lake of Arak is located at the boundary of the metamorphic zone of Sanandaj- Sirjan and Urmia-Bazman. The two main faults of Talkhab and Tozlugol (Tabarte) play a key role in the formation of this basin by right lateral movement and northwest - south east trend. In this study, morphotectonic indices were investigated to study the tectonic activity of these two faults. Altimeter integral index, Asymmetry index,Stream length gradient index, Basin shap factor Including measured indicators. Investigating the relative active tectonic using the above indicators shows that the Arak region has a moderate to high relative activity. Particularly, the separation region between the two Talkhab and Tozlugol faults is more active than other regions. The graben of the Meyghan Desert is formed due to the activity of the Tabakh and Thouzlugal faults during the Pleistocene by right lateral transpression zone. The southwestern side of the lake is in accordance with the Tozlugol fault. It seems that according to the morphometric studies of this area, the activity of the Talkhab fault is more than the Tozlugol fault and plays a more important role in the formation of the Meyghan lake.

      In order to study the provenance and metamorphic conditions of the Garmichay metapelites located in Northern Miyaneh, NW Iran the whole rock chemistry of this assemblage is investigated. Petrofabric scrutinizes have revealed the syn-tectonic nature of cordierite porphyroblasts (regional metamorphism) in the metapelites. Besides, C' shear band structures are observed. Two regional metamorphic (RMP1, RMP2), one contact metamorphic (CMP) and two deformation (D1, D2) phases are identified. The major oxide geochemistry implies two sedimentary progenitors: shale and greywacke. Based on major, rare earth and trace elements (Ti, Ni, TiO2, Zr and K2O) the igneous source rock has had andesite to dacite/rhyodacite nature. The chemical index of alteration and weathering indexes (CIA, CIW) imply a medium degree of alteration in the igneous progenitor. The Garmichay metapelites, in comparison with the PAAS and UCC, are enriched in Cs, La and Ce and depleted in Sr, Nb and Ta. The representative samples in the compatibility diagrams lie inside the paragenetic triangles that imply their stable conditions. Finally, based on the standard pseudosections the temperature and pressure range of the highest degree paragenesis has been 535-635 °C and 1-3 kb, respectively. Manuscript Document

      In the present research, to identify potential and existence of possible iron ore-bearing in the Maragh district of Bandar e Charak in Hormozgan province, first, remote sensing studies using Aster sensor data through ENVI were conducted. Afterward the preliminary exploration of promised regions was performed by magnetometry method. Remote sensing operation of the region data comprises preprocessing sequences of geometric correction by image-to-image method and atmospheric correction as well as processing techniques containing false color composite, banding ratio, least square-fit, directed principal component analysis and finally supervised classification through spectral angle mapper method. Because of this process, alteration-zoning map associated with iron mineralization in the studied region was produced. Magnetic data was acquired in an area of approximately 11.2 km2 in 1913 measuring stations using a proton magnetometer. Geosoft Oasis montaj software was employed for processing operation and qualitative interpretation of magnetic data via applying various corrections and filters including reduce to pole, upward continuation up to the variety of elevations, low-pass filter, derivative filters containing total horizontal derivative and analytical signal. At the end, to investigate the trend of magnetic anomalies observed on the surface, determination of approximate shape of the deposit and estimation of its depth, 3-D inverse modeling of the data was carried out. The results of the research through integrating two methods of remote sensing and magnetometry with 3-D inverse modeling of magnetic data, reveal that Maragh district has a high potential from viewpoint of iron ore-bearing. The results of this research will be applied for all of the geosciences practitioner especially geologists and exploration engineers. Manuscript Document
