| Abstract: | The Au deposit is in Late Palaeozoic the first period diorite body, Au-bearing quartz vein in subor- dinate fault fracture zone on both sides of Xiaoxinjie fault. In the original ore, the main ore grained natural gold, coarse--fine grained, also flake, needle, irregular Au. There are 4 stages of Au formation, the good Au formation stages are the second and third one. The ore deposit belongs to the quartz vein type Au deposit in the subordinate compression torsion fault of middle-high T diorite. |
