本文应用我国著名地质学家陈国达教授创立的地洼学说为理论指导,以地壳演化、构造演化和成矿演化三位一体的观点,从层控成矿角度,对我国地洼区层控铀矿床的大量实际资料、前人研究成果及本人工作实践,进行综合研究。得出我国绝大多数层控油矿床,均分布在现今地洼区构造单元中,成矿时间绝大部分在白垩—第三纪地洼阶段中晚时期,空间上常与中新生代红层盆地或印支、燕山期花闪岩类侵入体及火山喷发岩相伴,矿床组合上常与花岗岩型铀矿床、火山岩型铀矿床及铜、铅、锌、钨、钼、汞等矿床相关连。笔者认为,以地洼区为第三构造单元,详尽研究铀矿床及其伴生矿种的成矿规律,进行成矿预测,指导普查勘探工作,有极大的理论和实践意义。
In this paper, we use the theory of Diwa established by Professor Chen Guoda, a famous geologist in our country, as the theoretical guidance. Taking the Trinity of the crustal evolution, tectonic evolution and mineralization evolution as the trinity, Actual data, research achievements of predecessors and my own work practices, to conduct a comprehensive study. It is concluded that most of the stratigraphic controlled oil deposits in our country are distributed in the tectonic units in the present depression. Most of the metallogenic time is in the middle and late Cretaceous-Tertiary Diwa stage, which is often associated with the Mesozoic-Cenozoic red-bed basin Or Indosinian, intrusions from the Yanshanian amphibolite and volcanic eruption rocks. The ore-bearing assemblages are often associated with granitic uranium deposits, volcanic-type uranium deposits and copper, lead, zinc, tungsten, molybdenum and mercury deposits. In the author’s opinion, it is of great theoretical and practical significance to study the metallogenic regularity of uranium deposit and its associated minerals with the third tectonic unit of Diwa District, to conduct the prediction of mineralization and to guide the general survey and exploration.
