Fracture analysis in Lashotor stone quarry complex, south of Isfahan, a remote sensing approach

Fracture intensity map is important in quarries for correct location of face, reduce stone crushing and economic efficiency. In this study, the fractures surveyed in Lashotor stone quarry complex, 20 km south of Isfahan city as one of the most famous building stone quarries in Iran. Strike of major fractures are N-S, E-W and others are showing mostly NW-SE strike. The fracture intensity map was drawn in Arc GIS software for identified fractures based on augmented circular scaling method. Then Faces were mapped in fracture intensity map which demonstrate inactive faces exist in high fracture intensity areas .Thus, this kind of study is very important and needed for primary stages of exploration and extraction of building stone quarries. Also, Riddle model was drawn considering Kolah- Ghazi fault with strike of 135° and reverse and dextral strike- slip components. Identified fractures are almost fitted perfectly with the Riddle system of the Kolah- Ghazi fault.
