GEOLOGICAL CHARACTERISTICS AND EXPLORATION OF ZHUANMIAO BORATE DEPOSIT, LIAONING PROVINCE

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.
