摘要
铀矿赋存于∈_(1q)(清虚洞组)、∈_(2(?))(石冷水组)中,与黑色蚀变关系密切。矿化受F_1,F_2断层控制。根据矿床地球化学特征和区域地层铀的平均丰度,表明504铀矿床是以∈_(1(?))(牛蹄塘组)为矿源层的中低温热卤水强烈改造层控矿床。铀矿的形成与∈_(1n)有机质热裂解向石油转化以及石油的运移、逸散全过程有关。
The uranium ore exists in the Lower Cambrian Qingxudong Formation and the Middle Cambrian Shilengshu Formation and has a close relation to the black alteration. Its mineralization is controlled by the faults of F_1 and F_2. According to the geochemical features of the mineral deposit and the mean abundance of uranium in the regional strata, it shows that uranium deposit No. 504 whose source-bed is based on the Lower Cambrian Niutitang Formation is a strata-bound orc deposit strongly reworked by the hot bittern of low-medium temperature. The formation of uranium is related to the Lower Cambrian Niutitang Formation organie thermolysis to be transformed into petroleum and to the whole process of petroleum migration and release.
