芬兰的地理位置、植物、水系和土壤层决定了它的铀矿普查方法的特点。系统普查的规模较小,而且主要集中在石英岩发育区。寻找漂砾的方法对找金属矿和铀矿是有效的。由于冰川或严寒的作用,基岩剥落而成漂砾,追索和利用此种漂砾可以找到矿化露头。本文着重评价应用地面和航空放射性测量方法以及氡测定方法的有效性。用凯桑基的实例说明地面方法的成果。
Finland’s geography, flora, water systems and soil layers determine the characteristics of its uranium census method. Systematic census is relatively small in scale and is mainly concentrated in quartzite development. The way to find boulders is to find metal and uranium deposits. Due to glacier or cold, the basement rock peels off into boulders and recovers and exploits such boulders to find mineralized outcrops. This article focuses on the evaluation of the effectiveness of ground and aeronautical radioactive measurements and radon determination methods. Use Casey’s example to illustrate the results of the ground method.
