| 摘 要： | 扬子陆块区东南缘是碳硅泥岩型铀矿床的重要矿集区，其中沉积一外生改造型和沉积一热液叠加改造型铀矿床均分布在断陷红盆边缘或附近。通过红盆与碳硅泥岩型铀矿床分布规律的研究，提出了碳硅泥岩型铀矿床与红盆边缘断裂的沟通效应和控矿机制，旨在强调红盆在找矿实践中的权重。

| Abstract: | One of the important ore-concentrated areas of carbonaceous-siliceous-pelitic rock type uranium deposits is the southeast continental margin of Yangtze plate. Sedimentary-exogenous transformation type and sedimentary-hydrothermal superimposed transformation type uranium deposits are always distributed at or near the edge of down-faulted red basins. By analyzing the relation of deposit distributions to down-faulted red basins, the connective effect and ore-controlling mechanism of carbonaceous-siliceous-pelitic rock type uranium deposits are proposed with marginal fractures of red basins in the paper. |
