| 摘 要： | 根据成矿地质地球化学背景、矿体分布特征及稀土元素的分配模式,扎瓦拉金矿主要赋存于岩体外接触带二叠系～三叠系大理岩中,近南北向压扭性断裂破碎蚀变带是金的主要赋矿构造,金矿形成于印支期岩浆活动后期的断裂活动阶段,与矽卡岩化成矿作用没有直接的成因及时空联系,首次认为扎瓦拉金矿属中低温构造热液蚀变岩型,在岩体边缘近南北向断裂构造蚀变带中有形成中大型矿床的找矿远景。

| Abstract: | The Zhawala gold deposit is confined to the Permian-Lower Triassic marble and controlled by nearly north-southern shear fractured alteration zones. The deposit was formed by Indo-Chinese magmatism and faulting and was not in direct relation with skarnization. The deposit belongs to medium-lower temperature tectonic-hydrothermal alteration type with prospect of medium-large deposit in the north-southern fractured alteration zone around the magmatic mass. |
