| [摘 要] 金窝子金矿田大地构造位置上处于中朝-塔里木板块与哈萨克斯坦板块俯冲碰撞带南缘的北山中带。金窝子地区金矿床主要有两种类型，一是产在金窝子华力西期花岗闪长岩体中受ＮＮＷ向，陡断层控制的含金石英脉型金矿床；另一是产在上泥盆统金窝子组（D3j）地层中、受ＮＥ向低角度断层控制的蚀变糜棱岩型的金矿床。金窝子金矿的成矿时代远晚于金窝子花岗闪长岩体的侵位时间。金矿形成时间与剪切带的活动时代基本是一致的，表明矿体明显受区域构造的控制。 |

| Abstract: The Jinwozi Gold Deposit is located in middle Metallogenic belt,Beishan area,Gansu Province. Widely gold deposits developed in this Metallogenic belt. There are two main types of gold deposits in Jinwozi area. One is the lode gold deposits which is producted in Jinwozi Variscan granodiorite pluton controlled by the NNW-trending steep fault; Another is altered mylonite type gold deposits which is producted in the upper Devonian Jinwozi group (D3j) formation controlled by the NE trending low Angle fault. The Jinwozi Gold Deposit’s mineralization age is far later than its granodiorite pluton emplacement time, reflecting the hydrothermal fluids is not Jinwozi granitic magma to provide. Gold ore forming time and shear zone is basically the same age, indicates that ore bodies is controlled by tectonic obviously. |
