| 摘 要： | 罗家金矿为中低温热液黄铁绢英岩型金矿床。矿区NNE向断裂与其他方向断裂交会部位及其附近为金矿有利成矿部位,矿床具分带现象,花岗细晶岩脉与成矿关系密切。矿石类型以黄铁绢英岩型为主,含金石英脉型次之,矿石含金品位较高,并伴生较高的Ag,Cu等有益元素。通过对金矿床的地质特征、控矿因素及矿床成因的研究,在分析找矿标志的基础上,提出应进一步查证物化探异常,加大矿区深部及外围的找矿力度,以期发现新的金矿体。

| Abstract: | Luojia gold deposit is medium-low temperature hydrothermal sulfide altered rock type gold deposit.Faults with the trend of NNE and other faults broken parts are favorable for gold mineralization.Gold deposit has banding phenomenon,and granitic aplite veins has colse relation with gold mineralization.Ore types are majorly pyrite phyllic rocks,followed by gold-bearing quartz vein type.The grade of gold ore is very high and associated with higher Ag,Cu and other beneficial elements.Through study on geological characteristics of gold deposits,ore controlling factors and genesis research,on the basis of analyzing ore prospecting symbols,it is said that geophysical and geochemical anomalie should be furtherly verified,ore prospecting be strengthened in deposit in order to find new gold ores. |
