| Abstract: | A complete set of fault rocks from mylonite to cataclasite are present in the ore-hosted fractures at Xiaoqinling Au-ore area where microstructural phenomena are very common. The fractures are sinistral thrust-type ductile-brittle shear zones and formed by the hydrofracturing by the high fluid pressure. The cyclic crack of the fractures and cyclic sealing caused by the ore-forming fluids produced the multistage gold-bearing quartz veins. |
