新疆西昆仑岔路口—甜水海地区铅锌资源地球化学定量预测

新疆西昆仑岔路口—甜水海地区铅锌成矿地质条件良好,具很大的资源潜力。利用该地区最新的1∶5万化探成果,运用GIS技术,提取剥蚀程度、相似度和衬值等地球化学信息,通过建立典型铅锌矿地球化学预测模型,并在铅地球化学异常可信度分级基础上,采用类比法和面金属量法对区内铅锌资源量进行了定量预测,为该地区铅锌矿勘查工作部署提供了依据,同时也为地球化学勘查资料的深入开发应用提供了案例。

GEOCHEMICAL QUANTITATIVE PREDICTION OF LEAD-ZINC RESOURCES IN CHALUKOU-TIANSHUIHAI AREA OF WEST KUNLUN MOUNTAINS,XINJIANG

Chalukou-Tianshuihai area of West Kunlun Mountains in Xinjiang has favorable metallogenic geological conditions and con-siderable resource potential. Utilizing the newest 1 ∶ 50 000 geochemical survey data of this area and employing GIS technique, the au-thors extracted such geochemical information as erosion extent, similarity and contrast value and, on the basis of establishing the geo-chemical prognostic model for typical lead-zinc deposit and the grade of lead geochemical anomaly credibility, adopted analogue method and planar metallometry to make quantitative prognosis of lead-zinc resources in the study area, thus providing the basis for work de-ployment of lead-zinc resource exploration and also offering a case study for the deep-going development and application of geochemical exploration data.
