对瑞典北部隆瑟勒(Langsele)火山成因硫化物矿床金矿物学的研究结果表明,块状矿石中金和银的富集与交切矿体的侵入变粒玄岩脉有关。变粒玄岩脉的侵位使贵金属与方铅矿以及pb—Sb硫盐一起活化迁移到断裂带和低压带。隆瑟勒矿床高含量汞(平均 250ppm),影响到金的矿物学,因此,金以Au-Ag汞齐、自然金以及罕见的方锑金矿(AuSb_2)产出。电子探针分析的结果,以及对三元汞齐和合成的Au-Ag-Hg系列在成分上的关系进行探讨,汞齐成分多数为Au_(0.45)Ag_(0.45)Hg_(0.10).此外,还发现与辉锑矿呈蠕虫状连生的自然金。这种连晶被解释为方锑金矿在低温下的分解产物。
The gold mineralogy of the volcanicgenic sulfide deposits in the Langsele volcano in northern Sweden shows that the enrichment of gold and silver in massive ore is related to the intrusion of altered orebodies into metazoan veins. The emplacement of the metazoan dikes enabled the activation of precious metals along with galena and pb-Sb sulfur salts to migrate to the fault zone and to the low pressure zone. High levels of mercury in the Longserle deposit (250 ppm average) affect the mineralogy of gold, so gold is produced in Au-Ag amalgam, natural gold, and rare antimony gold (AuSb 2). The results of electron probe analysis, as well as the relationship between the composition of the three-element amalgam and the synthesized Au-Ag-Hg series, the composition of the amalgam is mostly Au 0.45 Ag 0.45 Hg 0.10 In addition, Also found with stibnite wormwood-like natural gold. This continous crystal is interpreted as a decomposition product of the Fang antimony gold ore at a low temperature.
