科罗拉多高原晚侏罗至早白垩世时期区域地下水流的定性和数字的模拟导出了在涌升溶液地区中铀沉淀的模式。古地形的再造表明,地表水系和由此产生的地下水流一般来说是向东和北东方向迳流的。在这些方向流动的地下水主要流经三迭-侏罗纪及二迭纪砂岩,进入由于埋藏的前寒武纪地块上升或下降所产生的不同厚度的沉积物中。埋藏的上升地块引起地下水沿其周围向上运移。这些推断的涌升水带与侏罗-白垩纪铀矿床的成矿密切相关。结果和涌升卤水与大气降水的混合及相互作用,并在两种水流动界面上引起铀沉淀的假设是一致的。铀是否来自界面之上或是其下部还是一个悬而未决的问题,但是,这个模式有助于更好地识别各种水的来源,同时也有助于发现找矿的目标区。
Qualitative and Numerical Simulations of Groundwater Flows over the Colorado Plateau from Late Jurassic to Early Cretaceous The pattern of uranium precipitation in areas of ascending solution was derived. The reconstruction of paleotopies shows that the surface water system and the resulting groundwater flow generally flow eastward and northeastward. Groundwater flowing in these directions mainly flows through the Triassic-Jurassic and Permian sandstones and into sediments of varying thicknesses resulting from the ascent or descent of the buried Precambrian patches. Buried rising blocks cause groundwater to migrate upward around it. These inferred surging horizons are closely related to the mineralization of the Jurassic-Cretaceous uranium deposit. The result is consistent with the hypothesis that the mixing and interaction of rising brine with atmospheric precipitation and uranium precipitation at both water flow interfaces is consistent. Whether or not uranium comes from above or below the interface is still an open question, but this model helps to better identify the sources of various kinds of water and also helps to find target areas for prospecting.
