集宁以东火山岩铀成矿带是一个较有远景的成矿带。本文在概要的阐述区域地质背景的基础上,着重讨论了该带的火山作用及其与板块活动的关系,提出了火山盆地分类和命名的基本原则。根据这些原则对本区火山盆地进行了较系统的分类,并归纳和总结了它们的基本特征及区域铀矿化的主要特点。指出本区铀成矿的火山盆地是上叠塌陷式、上叠沉陷式和上叠断陷式火山盆地,并分析了它们成矿的有利条件。在上述分析讨论的基础上,对本区区域成矿条件进行了综合分析,预测了一类成矿远景区有六个火山盆地,二类远景区有八个火山盆地,并指出了它们的找矿方向。
The volcanic rock uranium metallogenic belt east of Jining is a more prospective metallogenic belt. Based on a brief description of the regional geological background, this paper focuses on the volcanism of the belt and its relationship with plate activities, and proposes the basic principles for the classification and naming of volcanic basins. Based on these principles, we systematically classify volcanic basins in this area and summarize their basic characteristics and the main features of regional uranium mineralization. It is pointed out that the volcanic basins of uranium metallogenesis in this area are overlying collapsed, overlying and overlying subsidence type volcanic basins, and their favorable conditions for metallogenesis are analyzed. On the basis of the above analysis and discussion, a comprehensive analysis is made of the metallogenic conditions in this area, and it is predicted that there are six volcanic basins in one type of metallogenic prospect and eight volcanic basins in the second type of prospect, and their prospecting direction.
