青海茫崖十字沟地区铜镍多金属矿地质地球化学特征及找矿前景分析

Exploration of cliff cross ditch area in qinghai geological and geochemical characteristics and nickel copper polymetallic prospecting prospect is analyzed

通过在茫崖十字沟地区1:5万水系沉积物测量和1:1万土壤测量的系统开展,综合分析了地质背景、地质地球化学特征及岩石地球化学特征。结果表明:十字沟地区铜镍多金属矿的形成可能与超基性—基性杂岩体密切相关。分析认为深部应存在较大的超基性—基性含矿侵入体,显示出该区具有良好的成矿地质条件,成矿潜力较大,尤其于深部具有较好的找矿前景。

Through the exploration of cliff cross ditch area 1：50000 stream sediment survey and soil of 1：1 million measurement system developed, and the comprehensive analysis on the geological background, geological and geochemical characteristics and rock geochemical characteristics. The results show that the formation of copper-nickel polymetallic ore in the cross channel may be closely related to the ultrality-based complex. Deep analysis that should exist larger ultrabasic, basic ore intrusion, showing the good ore-forming geological conditions, mineralization potential is large, especially in deep has good ore prospects.
