钾长花岗岩中铀的射能效应对金矿脉的控制——以吉林古陆为例

The radiation effect of uranium in feldspar granite on the control of gold veins——a case study on Jilin ancient continent

钾化和铀常与大型金矿床相伴生。以吉林古陆为例,基于对吉林夹皮沟金矿和海沟金铀矿铀的性能深入性研究,发现铀的特性,即铀的计时性、稳定性、追踪性、射能性,特别是铀的射能性,构成吉林夹皮沟金矿和海沟金铀矿成矿主要条件之一,它从另一个侧面为大型、超大型金矿床的时空分布、形成条件、数值建模和成因研究等提供一条新途径。

Feldspar granite and uranium are commonly found in large gold mines.Taking Jilin ancient continent for example,after profoundly researching the properties of uranium contained in the gold ores of Jiapigou gold deposit and Haigou gold-uranium deposit,the authors find that the chronometric property,stability,tracing and radiation property,especially the radiation property,are the main mineralization conditions.This conclusion offers a new way of studying the space-time distribution,metallogenic conditions,numerical modeling and genesis of large and super gold deposits.
