摘要
x射线荧光探矿技术是金矿资源勘查工作中的一种新的手段。选定砷、锑、亲铜元素组作指示元素在湘中南碳硅泥岩型金矿进行X射线荧光测量,从而达到了寻找和圈定金矿化带,指明含金层位和矿化地段、指导山地工程、筛选化探样品之目的。本方法在现场直接测定快速、成本低,具有很好的地质和经济效益。
Abstract The X-ray fluorescence technique is a new means for the exploration of gold resour-
ces. Arsenic, antimony and chalcophile elements were selected as indicator elements to perform
X-ray fluorescence survey within carbonaceons-siliceons mudstone type gold deposits in central
south Hunan. As a result, we have attained the purposes of detecting and delineating gold mine-
ralization zones, pointing out auriferous horizons and mineralization sectors, guiding exploration
work and sieving geochemical samples.
This method enables ns to make on-the-spot direct determination and IB characterized by
rapidness and low coat, thus manifesting good geological and economic benefits.
