龙湾铀矿位于黔中‒湘西北成矿带,为贵州省第一个勘查发现的大型碳硅泥岩型铀矿床,其赋矿围岩主要为碳质泥岩与硅质岩。本文对龙湾铀矿硅质岩开展了LA-ICP-MS锆石U-Pb年代学和地球化学等方面研究。结果显示:①硅质岩的Al...展开更多 龙湾铀矿位于黔中‒湘西北成矿带,为贵州省第一个勘查发现的大型碳硅泥岩型铀矿床,其赋矿围岩主要为碳质泥岩与硅质岩。本文对龙湾铀矿硅质岩开展了LA-ICP-MS锆石U-Pb年代学和地球化学等方面研究。结果显示:①硅质岩的Al/(Al+Fe+Mn)值为0.16~0.41(平均0.25);Fe/Ti值为33~126(平均73);MnO/TiO2值介于0.16~0.74之间;MgO/Al2O3为0.67~4.21(平均1.78);指示其形成于大陆...
