Geological conditions and genetic analysis of the ore formation of the Labaigou Iron mine in North Qilian
The mining area is located in the North Qilian gully arc Basin system,affected by regional structure,the folds,faults and strata distribution are NW.Based on the study of ore-forming geological conditions,abnormal characteristics and orebody characteristics,it is found that the Lapaogou tungsten deposit is located in the North Qilian orogenic belt with complex structural geological conditions.Three tungsten ore bodies and one tungsten mineralized body were found in the mining area.The tungsten ore is 85m～200m long,4.14m～13.57m thick,and W2O3 grade is 0.11～0.39×10-2.In addition,the genesis of the deposit is closely related to volcanic eruption activities,and it belongs to(volcanic)sedimentation-metamorphic tungsten deposit.
