| 摘 要： | 在取得大量中子活化分析数据的基础上，应用元素丰度规律研究川北砂岩后认为：川北砂岩泥岩系是二元混合作用的产物，浅色砂岩与红色泥岩（或红色砂岩）具有不同的元素组合特征；含铀浅色砂岩与不含铀浅色砂岩均具有十分明确的地球化学指标；铀矿化只产在含铀浅色砂岩中。

| Abstract: | On the basis of neutron activation analysis and the rule of element abundance relationship,the authors suggest that the sandstone-claystone serties of northern Sichuan are the products of mixing processes of two end-members, that greendish sandstone and red claystones(or red sandstones ) have different characteristics of elementary assemblages, that uranium-bearing greendish sandstones and non-uranium sandstones have clear geochemical indicators, and that uranium minerallization only occurs in the uranium-bearing greenish sandstones. |

| Keywords: | rule element abundance mixing process end-members uranium-bearing greenish sandstone geochemical indicator |
