二连盆地白音塔拉地区210PO及地面γ照射量率特征分析

Characteristic analysis of ^(210)Po and ground γ radiation rate in Baiyintara area of Erlian basin

文章简要介绍了^(210)P_O及地面γ照射量率测量的基本原理及工作方法,结合区域地质概况对二连盆地白音塔拉地区^(210)P_O及地面γ照射量率特征展开了分析,并进一步探索了其与铀矿化的关系。实践证明:在我国北方中新生代沉积盆地中应用^(210)P_O及地面γ照射量率测量寻找砂岩型铀矿具有一定的效果,因地制宜地选用和合理配置可较好解决断裂、构造裂隙密集带,示踪深部铀矿化信息等地质问题,提高地质找矿效果,指导钻探工程部署。

This paper introduces the basic principle and working method of 210Po and γ exposure rate measurement.Combined with the regional geological characteristics,210Po and γ exposure rate characteristics is analyzed in two Erlian Basin white Tara sound area, and its relationship with uranium mineralization is research deeply. The practical results show that 210Po and γ irradiation survey is useful for sandstone type uranium deposit in the generation sedimentary basins in the north of China.Choosing reasonable configuration can solve these problems of the fault fractured zones, tracing deep uranium mineralization information and other quality problems and improve the effect of geological prospecting, guide the drilling plan.
