物化探在乔端一带钨矿找矿中的应用

Geophysical and Geochemical Survey Applied in Tungsten Exploration in Qiaoduan area

乔端钨金多金属矿位于瓦穴子—乔端贵金属、多金属成矿带南侧,成矿条件十分有利。但和相邻的栾川大型、超大型钨钼矿区相比,本区钨矿找矿工作至今未获突破。为此,通过土壤次生晕、岩石原生晕、激电中梯剖面测量、高精度磁法等物化探方法,结合矿区遥感地质解译、围岩蚀变等地质特征,预测工作区存在斑岩型钨矿。物化探综合找矿方法的应用,是今后北秦岭地区钨矿勘查的有效手段。

Qiaoduan Tungsten-gold Polymetallic Mine is located on the south side of the Waxuezi-Qiaoduan precious metal and polymetallic metallogenic belt,and the metallogenic conditions are very favorable.However,compared with the adjacent Luanchuan large-scale and super-large tungsten-molybdenum deposits,the prospecting work of tungsten deposits in this area has not yet achieved a breakthrough.This time,through geophysical and geochemical exploration methods such as soil secondary halo,rock primary halo,IP ladder measurement,and high-precision magnetic profile,combined with geological features such as remote sensing geological interpretation and wall rock alteration in the mining area.It is predicted that there will be porphyry tungsten depositin the work area.The application of comprehensive geophysical and geochemical prospecting is an effective method for tungsten ore prospecting in the North Qinling area in the future.
