摘要
“波西米亚地块”是世界重要的铀资源产地之一，本文强调了该区超大型多因复成铀矿床的特征，分析了该区成矿的历史－动力学大地构造背景，认为该区超大型多因复成铀矿床的形成是因为具有富铀的前地槽残留稳定陆壳基底、长期活动的深断裂带、富铀的有利岩性建造和后期强烈的地洼型构造岩浆活化作用的结果。通过对比分析，指出中国华南地区存在相似的区域成矿地质条件，具有寻找超大型多因复成铀矿床的前景。
Bohemian Massif is one of the most important producing area of uranium resources in the world.This paper summarizes the features of superlarge polygenetic compound uranium deposits,analyses the geotectonic setting of ore formation in the Bohemian Massif and makes a conclusion that the geologicial conditions for forming superlarge polygenetic compound uranium deposits are palaeo-crustal basement rich in uranium,deep-seated fault zones, over-riding favorable facies formation rich in uranium and intense tectono-magmatic activation. Bdsed on the analysis and discussion,the author indicates that the Southeast Chind diwa region possessed the similar ore-forming condition and prospecting of discovering superlarge polygenetic compound uranium deposits.
