相山铀矿田侵蚀程度研究

Study on corrasion depth in Xiangshan uranium ore field

矿床的形成和保存是矿床学研究的两个重要方面。相山地区发育明显的新构造运动,地表总体侵蚀严重,相山峰顶侵蚀深度约为3000 m,铀矿床遭受了一定程度的侵蚀作用,邹家山一带侵蚀深度>757 m,邹家山铀矿床刚好侵蚀到矿化的前峰位置。从矿田西北部到东南部,地表侵蚀深度逐渐加大。西北部矿床保存条件良好,多数铀矿床完整或较完整地保存下来,是深入找矿、扩大远景的主攻方向。

The process of ore formation and reservation are two important study field of metallogeny. In Xiangshan area, new tectonic movement is rather strong, the terrains is eroded heavily, deposits suffered different erosion. The erosion depth at the summit of Xiangshan is about 3000 m, and in Zhoujiashan area, the erosion depth is over 757 m, this is just the top depth of the ore body. In plane, the erosion become deep and deep from the northwest to the southeast of the orefield. So in the northwest, the deposit can reserved well and therefore it is the favorable area for prospecting the deposit in depth.
