| 摘 要： | 笔者认为新发现的川西北某金矿床与热液浸染交代的卡林型金矿床类型可以类比，成矿受断裂、破碎带控制；赋矿层主要为危关群泥灰岩；自然金呈微细粒和显微细粒赋存于黄铁矿、毒砂及褐铁矿之中。矿石氧化程度高，杂质含量低，易选治。

| Abstract: | A newly discovered Gold Deposit in Northwest Sichuan is controlled by fractures and fractured zones. It may be correlated to Carlin-type gold deposit. Host rock is marl of the Weiguan Group. Native gold as fine grains and micro grains occurs in pyrite, arsenopyrite and limonite. Gold ore is intensively oxidized and characterized by low impurity and easily sorting. |
