薄竹山矿集区东部小平坝矿区地质-地球物理-地球化学异常特征

Characteristics of Geology-geophysical-geochemical Nomalies of the Xiaopingba Deposit Lies in the East of Bozhushan Granite

小平坝矽卡岩型白钨矿床位于薄竹山矿集区东部,钨多金属矿产于寒武系、奥陶系碳酸盐岩与黑云母二长花岗岩体接触带,磁异常、激电异常、土壤地球化学异常特征及分布与矿体空间形态密切相关。通过对矿区的地质、地球物理、地球化学异常特征的分析归纳,提出了地质-地球物理-地球化学找矿标志,为矿区进一步勘查提供理论依据。

The Xiaopingba Scheelite Deposit lies in the east of Bozhushan granite, southeastern Yunnan. The ore bodies are mainly produced in the contacts parts between granite and Cambrian, Ordovician carbonate rocks. The nomalies of high precision magnetic survey, induced electric medium gradient method and soil geochemical are closely to the distribution of the deposit and the contacts parts. On the basis of a system study on the geological, geophysical ,geochemical anomalies characteristics of the deposit, integrated geological geophysical geochemical prospecting criteria are put forward. This research result will provide an important theory basis for further prospecting in Xiaopingba Scheelite Deposit.
