辽宁宽甸砖庙硼矿区成矿地质特征及找矿
GEOLOGICAL CHARACTERISTICS AND EXPLORATION OF ZHUANMIAO BORATE DEPOSIT,LIAONING PROVINCE
【摘要】 通过对砖庙硼矿区野外地质、地球化学、数学地质等深入研究,提出了研究区硼矿床经历了沉积成岩成矿作用和变质-混合岩化改造成矿作用两个成矿期,为沉积变质改造型硼矿床.本次研究工作查明了该区硼矿体总体向西侧伏的规律和北北东向断层为倾角小于40°的逆断层,并以此为指导,在逆断层下盘找到了栾家沟硼矿、花园沟硼矿、二人沟硼矿3个大型隐伏硼矿床,取得了重大找矿突破.
【Abstract】 With study on field geology,geochemistry and geomathematics for the Zhuanmiao borate deposit,it is concluded that the borate mineralization within the studied area underwent two epochs,i.e.sedimentation and metamorphic migmatizaiton,implying its sedimentary-metamorphic type of deposit. The ore bodies in general dip to west. The NNE-orientated faults in the ore field are reverse occurrence with dip angles less than 40°. Consequently,three large-sized concealed deposits were discovered within the lower walls of the faults,marking a breakthrough in the exploration for borate deposits in the area.
