چکیده مقاله :
این پژوهش برای تحلیل هندسی و جنبشی تاقدیس خانه سرخ بهمنظور شناخت سبک ساختاری انجام شده است. چین-خوردگی خانه سرخ، تاقدیسی طویل و باریک است و در اثر لغزش برروی سازند گرو در منطقه لرستان قرار گرفته است. سازند گرو یک سطح جدایش میانی در منطقه می باشد. بهمنظور تحلیل هندسی این تاقدیس، سه برش ساختاری عمود بر اثر سطح محوری چین ترسیم شده است. بر اساس تحلیل هندسی برشهای عرضی و مقایسه پارامترها با انواع مدل های متفاوت چین های مرتبط با گسل های رانده، می توان پیشنهاد کرد که تاقدیس خانه سرخ در دسته چین های جدایشی گسل خورده قرار دارد. بنابراین هندسه چین جدایشی و تکامل جنبشی تحلیل شده برای تاقدیس خانه سرخ بر اساس مدل ارائه شده معتبر است.
This research has been carried out in order to understand geometric and kinetic analysis of the khaneh Sorkh folding and its structural style. Khaneh Sorkh folding is a long and narrow anticline that is formed due to sleep in the Garau Formation which is located in the Lorestan region. The Garau Fomation is the intermediate detachment layer in the Lorestan. In order to carry out geometric analysis, three structural cross sections were drawn perpendicular to the axial surface trace on this anticline. Thus, based on the analysis of the geometry of cross sections and comparing parameters with variety of models, it could be suggested that the Khaneh Sorkh Anticline is a detachment fold in the thrust fault-related folds. Finally,geometry of faulted detachment fold and analysed kinetic evolution is valid for Khaneh Sorkh Anticline based on the proposed model.
