| 摘 要： | 广西贵港六梅金矿床位于贵港市龙山矿田福六岭金矿区,为微细浸染型金矿床。矿床中主要矿石矿物为毒砂和黄铁矿。通过载金矿物毒砂和黄铁矿含金性、金浸出提取、晶体结构测定等方法,查明矿床的金存在形式。浸出率试验中平衡计算表明,载金矿物毒砂中的晶格金形式约占25%,超显微包体形式金约为75%。矿床流体包裹体测温和稀土元素地球化学研究表明,六梅金矿床为中-低温热液型矿床,成矿物质来源与地层有关。 |
| 关 键 词： | 广西六梅金矿床 载金矿物 金的赋存状态 成矿条件 |

| Abstract: | Liumei gold deposit is located in Fuliuling gold mining area of Longshan mine field in Guigang,Guangxi,China.The deposit belongs to carlin-type gold deposit.Arsenopyrite and pyrite are the major gold-bearing minerals in the deposit.In order to know the existing state of gold in the deposit,auriferous features analysis,gold leaching extraction analysis and crystal structure determination analysis on arsenopyrite and pyrite are carried out.In arsenopyrite,about 25% of the Au exist in the form of lattice,and 75% exist in the form of ultra-microscopic inclusions.Fluid inclusion microthermometric and REE geochemical studies indicate that the Liumei gold deposit is a meso-epithermal hydrothermal deposit,in which the mineralizing material is related to the strata. |
| Keywords: | Liumei gold deposit gold-bearing mineral existing state of gold deposit's forming condition |
