云南澜沧县三岔河坝子勘查区土壤地球化学特征

Soil geochemical characteristics in Sanchahe Bazi exploration rights area,Lancang county,Yunnan province

选择云南省澜沧县三岔河坝子铅锌矿勘查区的西部,在前期1︰25 000土壤地球化学勘查的基础上,按100m×40m网度开展1︰10 000土壤地球化学测量。分析Au,Ag,As,Co,Cr,Cu,Ni,Pb,Zn,Mo,Mn 11个元素,选取主要指示元素Pb,Zn,Ag,Cu,Mo异常区进行分析后,划分了10个组合元素异常区,圈定出9个靶区,包括1个A类靶区,5个B类靶区和3个C类靶区。

Based on the previous geochemical survey at scale 1 ： 25000 the west Sanchahe Bazi explora- tion rights area is chosen to conduct soil geochemical survey at 100 m×40 m grid and scale 1 ： 10000. 11 elements of Au, Ag, As, Co, Cr, Cu, Ni, Pb, Zn, Mo, Mn are tested. According to the results anomly indica- tors of Pb,Zn,Ag,Cu,Mo are delineated and the element combination anomly also delineated. By analy- zing the anomlies 1 target A, 5 target B and 3 target C are delineated.
