| Abstract: | The No. 9 gold-bearing quartz-vein is the largest one in the Jindingcha Ore area. It is located near the axis of Laoyacba anticline. The plastic deformation of quarty is better in the vein. The ore texture is dominatedby hydrotbermal filling and replacement. The gold occurs in micro-and altramicrogod. The microgold presentsin intergrains, fractures and inclusions. Pyrite is the most important gold-carrying minreral |
