摘要
包裹体氧气找矿是一种新的铀矿找矿方法,可分为基岩包裹体氡气法和水系沉积物包裹体氧气法两种。前者适用于寻找隐伏盲矿体,后者主要用于确定成矿远景区。花岗岩、火山岩地区热液铀矿的大量实验均取得了良好的结果。包裹体测氡找矿可以适应铀矿找矿的不同阶段,与现有的找矿方法及包裹体蒸发晕、热晕找矿方法相比,具有简便易行、所用人力物力少、速度快、经济效益高等特点。
Radon measurement in mineral inclusions provides a new method of uranium prospecting. Bothsolid rocks and water system sediments can he sampled for this purpose. Sediments inclusion radonis used for orientating prospective area, while solid rock inclusion radon for locating the blindore bodies. Successful tests have been carried out in granite and volcanic areas for hydrothermaltype uranium ores. To compare with the conventional prospecting methods and methods of evapo-ration aureole and thermal aureole. the radon approach is simpler and more effective. suitable forvarious stages of uranium ore prospection.
