| 摘 要： | 分析研究了320矿区当冲组“硅化带”的形态、成分、结构、构造特征，应用构造地球化学原理，阐述了“硅化带”及其铀化矿的形成的过程。并表现出岩控、层控、构控、时控及“沉积－构造热液再造”等特点。当冲组富铀岩层不仅成为矿提供了物质基础，而且是矿床产生的直接围岩。

| Abstract: | In the paper, The geometry, ingredient, structure and structural feature of the silicified zones of the Dang Chong Formation in ore area NO.320 is analyzed. The forming process of the silicified zones and uranium mineralization is explicated in term of tectronogeochemical theory. There appear some feature, Including rockbound, strabound, tectonobound, time controlling and deposition-hydrothermal rebuilding type and so on. The conclusion is drawn that the rocks formation with plenty of uranium In Dang Chong formation not only contributes its basic material to mineralization, but also is the main wall rock for ore location. |
