本文对瑞典北部谢莱夫特矿区兰赛火山成因的硫化物矿床中金的矿物学进行了研究,在块状矿石中,金、银的富集和侵入的变粗玄岩脉有关。该岩脉切穿矿床。由于变粗玄岩侵入矿体,所以使贵金属和方铅矿,及方铅矿和铅、锑疏盐一起活化转移到断裂带及低压区。因为兰赛矿床,具有高汞含量(平均250ppm),对金的矿化有很大影响。所以金是以金银汞齐、自然金、以及少量的方锑金矿(AuSb_2)产出。汞齐矿物晶簇的电子探针分析结果为Au_(0.45)Ag_(0.45)Hg_(0.10)。本文探讨了三记汞齐的成分与Au-Ag-Hg系合成的关系。还发现自然金与辉锑矿共生呈蠕虫状,这是在低温下由方锑金矿破裂而生成的。
In this paper, the mineralogy of gold in the sulphide deposits of the Lansai volcano in the Skellefte mine area in Northern Sweden is studied. In the massive ore, the enrichment of gold and silver is related to the intrusive, thickening of the dhyantic veins. The veins cut through the deposit. Due to the invasion of coarse basalt into the orebody, the noble metal and galena, together with galena, lead and antimony and salinity, are activated and transferred to the fault zone and the low pressure zone. Because of the Lancet deposit, which has a high mercury content (an average of 250 ppm), it has a significant impact on the mineralization of gold. So gold is amalgam, natural gold, and a small amount of antimony gold (AuSb_2) output. The result of electron probe analysis for the amalgam mineral clusters is Au 0.45 Ag 0.45 Hg 0.10. This article explored the relationship between the composition of the triple-amalgam and the synthesis of the Au-Ag-Hg system. Also found that natural gold and stibnite coexist was worm-like, which is generated at the low temperature by the Fang antimony gold ore rupture.
