| 摘 要： | 对富金钠长石岩的岩石化学、微量元素及稀土元素分析显示,大沟谷钠长石岩与区域上震旦系乐昌峡群片岩及附近花岗岩没有成因联系.富金钠长石岩主要是热水沉积形成的.钠长石岩与金矿有紧密的内在联系,钠长石岩型金矿床是热水沉积+改造作用形成的.

| Abstract: | agougu gold deposit,occurring majorly in the albitite belt of Sinian Lechangxia group,is a new type of deposit related to albititeThe study on the geochemistry,trace elements and REE of the Au rich albitite shows that the albitite has no genetical relation to the schist of Lechangxia group and nearby granite.The Au rich albitite was formed mainly by hydrothermal sedimentationThe albitite is closely related to gold depositThe genesis of the albitite type gold deposit is hydrothermal sedimentation + reformation |

| Keywords: | gold deposit albitite petrogenesis hydrothermal sedimentation Guangdong Province |
