摘要
９号含金石英脉是金硐岔金矿区内最大的金矿脉，分布在老鸦岔背斜轴部附近．金矿石以热液充填－交代组构为主．金呈显微金、超显微金状态赋存，显微金多呈．粒间金、裂隙金、包金．黄铁矿是最主要的载金矿物．
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
