Surfer在江西省遂川县金坑金矿找矿中的应用
|
摘要
以江西遂川金坑土壤化探采样为研究对象,对研究区内土壤中微量金属元素的化探数据进行了分析,运用Surfer软件对其进行残差计算,滤波分析,最终生成克立格网格,并对其进行平面等值线成图,用以对比趋势面生成等值线图,完成对化探异常的圈定,得出上下金坑为重点勘查区域的结论,为下一步确定勘查靶区提供了有力的技术支持。
In this paper,soil samples obtained by geochemical exploration in Jinkeng region,Suichuan county,jiangxi province,were taken as research object,the geochemical data of metal elements which mainly refer to Au were analyzed.The residual calculation and filter analysis on the geochemical data were carried out,and a Kriging grid was made.Then,the isogram made with the grid and the isogram made by trend surface analysis was compared,the geochemical anomalies areas of Au were delineated.The conclusion is that the zone key exploration zones should be in Shangjinkeng and Xiajinkeng.The study provides powerful technical support for the further determinant of exploration target areas of gold deposit.
