伽玛能谱快速找金方法及其应用

Rapid Gold Prospecting and Application of r-Energy Spectrum

选用携带式微机伽玛能谱仪测定岩石、土壤中钠、社、钾及其放射性总量，能定量或半定量地估算某些含金地质体中的金含量。对新疆某地进行地面、井下测定，新发现金矿脉一条，金储量６２４ｋｇ；圈定４个金矿化段，２个富集金地段；验证评价２个综合化探晕圈，快速评价２个金矿区和８个金矿点；特别对井下预测金品位准确可靠，能及时指导矿区井下采掘。

Using portable renergy spectrum equipment to measure the contents of uranium,thorium and potassium and their total radioactive amount in rocks and soils,the gold content in several gold containing geologic bodies can be calculated quantitatively or semiquantitatively. One new gold veins with 625kg reserve and four mineralized and two enriched sectors have been discovered by ground and underground surveying in the testing region. As two integrated geochemical exploration aureoles were confirmed and evaluated and two gold ore districts and eight gold spots were evaluated quickly,the method is proved to be more reliable and precise for the prediction of content and grade of gold in underground,directing underground mining in time.
