【摘要】 <正>自1963年在苏联的塔尔纳赫铜镍硫化物矿床中发现硫铁铜矿(talnakhite)以来,未见有新产地的报导。笔者在做治岭头金矿物工作时,在光片中发现一种反射色与黄铜矿相似的矿物,放置几天后随即变成与斑铜矿氧化后之颜色相似的色调。经过电子探针分析和 X 光粉晶分析证实,该矿物与苏联的诺利斯克的塔尔那赫矿床的硫铁铜矿相当。不过本矿床的硫铁铜矿产于与火山岩有关的金银矿床中,此外,在光性、物性与化学成分上也与塔尔那赫矿床的硫铁铜矿有一定的差别。更多还原

【Abstract】 Talnakhite has been recognized in gold-bearing quartz veins within the lower Paleozoic Zhilingtou biotie-plagioclase gneiss of Zhejiang Province.This mineral is characterized by a certain amount of Ag(from 0.1 to 4.22 wt%)and the reflectance much higher than the talnakhite from the Norilsk deposit of the U.S.S.R..The gold- bearing quartz vein deposit is genetically related to the Mesozoic volcanic hydrothermal activities;it might be therefore considered as a new geological occurrence.更多还原
