| 摘 要： | 衡阳盆地砂岩型铀矿赋存于白垩系上统至古近系古新统浅色层内。下白垩统神皇山组及东井组为棕红色碎屑沉积,与上白垩统及古近系高岭组构成1个大的沉积旋回,而产铀的戴家坪组、车江组、枣市组、茶山坳组以岩层的颜色、粒度变化构成多个沉积韵律。文章通过对该盆地中的砂岩型铀矿床的产出地质背景、矿床地质特征进行研究,探讨矿床的成因、成矿模式及找矿模型,期望为深入的找矿工作提供依据。

| Abstract: | Sandstone type uranium deposits in Hengyang basin is occurred in light colored layers of Upper Cretaceous to Paleocene strata.The lower Cretaceous Shenhuangshan formation and Dongjing formation are brownish red clastic rocks,which constitute a larger sedimentary cycle with the Upper Cretaceous and Paleocene rocks.The uranium hosting rocks in Daijiaping formation,Chejiang formation,Zhaoshi formation,Chashanao formation comprise several sedimentary rhythm by the change of grain size and color.The regional geology setting of the basin,geological feature and the genesis of Wangjiachong uranium deposit were studied,the metallogenic and prospecting model of sandstone type deposit were summarized so as to provide references to the future uranium exploration. |
