西藏邦卓玛地区土壤地球化学特征及找矿预测
Geochemical Characteristics of Soil and Prospecting Prediction of the Bangzhuoma Region, Tibet
摘要
Abstract
Based on a 1∶10000 geochemical soil survey in the Bangzhuoma area of Tibet,this work carried out a geochemistry statistic analysis on 12 kinds of microelements from the survey using eiement variation coefficients and enrichment and discrete characteristics,and discussed the metallogenetic potentials of the 12 kinds of microelements.It was concluded that the five elements of Au,Ag,W,Pb,and Sb have great ore-forming potentials.By correlation and factor analyses,we established the combination characteristics of elements in the area,which can be divided into Au-Ag-Cu-Bi-W,Pb-Sn,and Sb.Meanwhile,by using the contrast value anomaly method,this article delineates the combination anomaies in this area.The results show obvious combined anomalies which match well with each other,roughly distributed in NW direction with a monilform shape.This work also delineated four important target areas on the basis of combined contrast anomaly superposition,which provide theoretical evidence for the next work of searching for multi -metals including Au,Ag,Sb,W,and Pb in this area.关键词
