综合物化探在浙西北某矿区多金属矿勘查中的应用

浙西北某矿区位于浙江省开化桐村—淳安梓桐重点勘查区内,是多金属成矿的有利区块,但以往物化探工作程度低,找矿一直未取得突破。文中以大铜坑矿段为例,利用地面高精度磁法、土壤地球化学测量和CSAMT等多种物化探方法,结合区内的成矿地质条件,对综合物化探异常作出了解释推断和综合评价。经钻探验证,物化探异常指明了找矿方向,取得了理想的地质效果,并对相邻矿段下一步地质找矿工作起到了指导作用。

The application of integrated geophysical and geochemical exploration application to metallic ore exploration in a mining area of northwest Zhejiang

The studied mining area of Zhejiang province is located in Tongcun of Kaihua?Zitong of Chun'an key exploration area in northwest Zhejiang. It is a favorable block of polymetallic resources, but its previous geophysical and geochemical prospecting work degree is low, with no breakthrough achieved. With the large copper pit mine as an example, the authors used ground high precision magnetic method, soil geochemical survey, CSAMT method and other geophysical and geochemical methods in combination with geo?logical conditions to conduct comprehensive geophysical and geochemical anomaly interpretation and comprehensive evaluation. Drill?ing verification shows that geophysical and geochemical anomaly can indicate the direction for prospecting and achieve ideal geological effects, and can also play a guiding role in the further geological prospecting work of the neighboring ore blocks.
