松辽盆地南部协尔苏凹陷铀成矿控制因素与成矿模式探讨

Discussion on ore-controlling factors and metallogenic model of uranium ore-formation in Xieersu depression,south Songliao Basin

通过对协尔苏凹陷地质特征的研究,认为协尔苏凹陷铀矿(化)为后生多期次叠加改造成因,其形成主要受铀源、构造、目的层沉积体系、层间氧化带发育程度和地下水动力变异等因素控制。在总结上述控制因素的基础上,初步建立了成矿模式。

Based on the geologic characteristics of Xieersu depression, uranium mineralization in this area is believed to be sandstone type of epigenie genesis of multi times superimposition and the ore-formation is mainly controlled by the factors such as the uranium source, the development of interlayer oxidation zone, the variation of hydrodynamic conditions, etc.. A preliminary metallogentie model has been set up.
