| 中文摘要:鄂尔多斯盆地东北部砂岩型铀矿与古层间氧化带具有密切的联系。文章通过对直罗组不同蚀变分带砂岩的常量元素含量的统计与分析,揭示了各常量元素的变化规律。其中,Si、Al、Fe、Ca的活动性较为强烈;Na、Mg、K的活动性相对较弱;Mn、Ti、P则比较稳定。通过研究,认为成岩作用、水-岩作用、油气二次还原作用、铀成矿作用以及环境的变化是常量元素含量变化的主要影响因素。 |

| Abstract:There is a close relationship between the sandstone-type uranium deposit and the ancient interlamination oxidized zone in northeastern Ordos Basin. This paper reveals the change law of each major elements by statistics and analysis on the major elements content in different altered sandstone in the Zhiluo Formation. Among them, Si, Al, Fe and Ca has relatively strong activity; the activity of Na, Mg, K is relatively weak; Mn, Ti, P is stable. The research shows that diagenesis, water-rock interaction, oil and gas reduction, uranium mineralization and the change of environment as the main factor of the changes of the major elements content. This papar has theoretical significance for formation mechanism of ancient interlamination oxidized zone and uranium mineralization mechanism. |
