伊犁盆地南缘蒙其古尔铀矿床越流补给成矿作用

THE MORE CURRENT SUPPLY OF MENGQIGUER URANIUM ORE DEPOSITS IN SOUTHERN MARGIN OF YILI BASIN

以铀成矿理论为指导,通过地质剖面、水文地质剖面的绘制,研究蒙其古尔铀矿床水动力特征,结合地层特征、层间氧化带发育特征,探讨成矿流体在越流补给成矿过程中所起的作用.认为条件较好的"水动力窗"是越流补给成矿的先决条件,初步建立"越流补给"的成矿模式.

In this paper,guided with the uranium mineralization Theory,Through the draw of the geological section,hydrogeological profile.Studied the hydrodynamic characteristics of Mengqiguer uranium deposits,Combined with stratigraphic characteristics,development characteristics of interlayer oxidation zone,and Investigate the role of the Ore-forming fluids in the mineralization process,We believe that with better conditions,＂Water Power Window＂ is more flow of supplies a prerequisite for forming,and Initially established a ＂cross-flow supply＂ of mineralization.
