摘要
斗华岭金矿位于醴陵-浏阳成矿带上,矿区出露的地层主要为中元古界冷家溪群的浅变质岩系,为矿区主要的矿源层。矿区主要的构造方向为NE向,矿体赋存在NE向的断层中。区内岩浆活动为成矿流体提供了热能,并驱动含矿流体的循环。研究表明,成矿流体主要来源于大气雨水,混有岩浆水的加入,流体包裹体均一测温显示矿床形成的温度在149~224℃,矿床成因类型为中低温热液矿床。
The gold deposit of Dou Hualing is lacated in the Liling-Liuyang metallogenic belt.The orearea exposed mainly Mesoproterozoic Lengjiaxi group grade metamorphic series,as the main source of ore mining.Construction of the deposite is to the NE direction,and the orebody is lacated in the NE trending fault.Magmatic activities in the region provide the heat for the ore-forming fluids and driven fluid cycling.The research show that the main ore-forming fluids is from atmospheric water,mixed with magmatic water.Homogenization temperature of fluid inclusions show that the temperature of depost is in 149~224 ℃.The genesis of the deposit is epithermal type deposit.
