摘要
萨尔朔克金矿是近年来在阿舍勒大型铜锌多金属矿区外围发现的一种新的金矿类型,具有特殊的矿化特征。对矿床稀土元素特征的研究结果表明,矿床成矿物质主要来源于次火山围岩,但成矿具有多源性。不同类型矿石的稀土含量具有明显差异,表明矿床形成至少经过两期主要的热液活动。
Saersoc gold deposit, a new type of deposit recently discovered in Ashele large scale Cu-Zn ore district surroundings, has special ore-forming characteristics. According to 25 samples collect at random from rocks and ores, REE have the following characteristics:∑LREE/∑HREE ratios of the all samples are higher than 1, ores and rocks show strong to moderate negative anomalies of Eu. The REE mode of most ores are similar to the mode of the wall rocks and near-ore wall rocks, it is shown that ore-forming materials came mainly from host wall rock. But they are of multisource nature. REE total amounts of different type ores have obvious distinction. Moreover, it is pointed out that gold deposit had been formed by two-term hydrothermal activities at least.
