摘要
通过辽宁核地地质调查院编写的辽宁省建昌县大屯镇老沟口矿山详查报告,以及20世纪80年代和90年代多个单位的工作成果。基本查明区内矿体的赋存形态、产状、规模、矿石质量情况。矿区南部出露大面积多期活动的元古代、中生代酸性侵入体。本区断裂构造不发育,主要为小的断层,呈近东西向产出。对该矿区的地层、构造、岩浆岩等地质特征有了更清晰的了解,圈定工业矿体,估算保有资源量,为矿山下一部建设提供地质依据。
Through the detailed survey report of laogoukou mine in Datun Town,Jianchang County,Liaoning Province compiled by Liaoning Nuclear Geological Survey Institute,and the work achievements of many units in the 1980s and 1990s.Basically find out the occurrence form,occurrence,scale and ore quality of the ore body in the area.A large area of Proterozoic and Mesozoic acid intrusions are exposed in the south of the mining area.The fault structure in this area is undeveloped,mainly small faults,which occur in nearly east-west direction.We have a clearer understanding of the strata,structure,magmatic rock and other geological characteristics of the mining area,delineate the industrial ore body,estimate the retained resources,and provide geological basis for the next construction of the mine.
