赣杭构造火山岩铀成矿带区域地球物理场分布特征及找矿意义

THE DISTRIBUTION CHARACTERISTICS AND PROSPECTING SIGNIFICANCE OF AREAL GEOPHYSICAL FIELD IN GAN-HANG TECTONO-VOLCANIC METAL- LOGENETIC BELT OF URANIUM

本文在简述赣杭构造火山岩铀成矿带区域地球物理场分布特征的基础上,着重讨论了区域地球物理场与铀矿化的空间分布关系,代表性铀矿床(田)的区域地球物理场特征及其组合类型,指出了“多位一体”的地球物理场组合是铀成矿的最佳组合。根据组合类型,对全带矿床、矿点进行分类排队,并为全带远景评价提供了依据,对下一步工作提出了建议。

Based on brief description of the fundamental characteristics of areal geophysical field in Gan-Hang tectono-volcanic metallogenetic belt of uranium, this paper emphatically discusses several problems such as the spatial distribution relationship between areal geophysical field and uranium mineralization, various features of regional geophysical field for each typical uranium deposit (ore field) and their composite types. It is presented that the composite type of geophysical field in respect to 'multi-position in one body' should be the best one to uranium metallization. According to composite types, ore deposits (occurrences) are classified and arranged in order, providing the basis for the potential evaluation in the whole belt. Suggestions on the work in the future has thus been made.
