压溶角砾岩出现征构造带的较深部位并与构造角砾岩伴生,它是碳酸盐岩石构造破碎的一种特殊型式。压溶角砾岩由不同方向的缝合线发育而成,胶结物主要是碳酸盐岩的不溶残余物。碳酸盐岩中的铀含量主要与不溶残余物有关。在压溶作用发育过程中,岩层中的铀被活化、渗滤,在有利的物化环境中被炭、泥等吸附而富集,也可与其它成矿作用叠加而成矿。
Compacted breccia appears to be deeper in the tectonic belt and is associated with tectonic breccias. It is a special type of crushed carbonate rock structure. Pressure-dissolved breccias are formed by sutures of different orientations, and cements are mainly insoluble residues of carbonate rocks. Uranium in carbonate rocks is mainly associated with insoluble residues. During the process of depressurization, the uranium in the rock is activated and percolated, and is adsorbed and enriched by carbon, mud and the like in a favorable physical and chemical environment. It can also be superposed with other mineralization and mineralization.
