一九八四年,笔者在研究广西芒场锡多金属矿床的矿石组分时,发现了在国内、外尚未见报导的、自然铋—锑固溶体系列的两个变种矿物-锑—自然铋和铋—自然锑。同时,还发现了国内第一个硫锑铋铁矿,其数据与意大利一铜铁矿床对比,几乎完全相符。它们的发现,不仅扩充了锡矿床的矿物种,同时也具有矿物学、地球化学和矿床学方面的研究意义。一、地质产状本矿为锡多金属矿床。主要矿体有脉状和网脉似层状两种。矿体产于芒场背斜及其两翼的中泥盆统纳标组和罗富组一些浅海相碎屑岩和其热变质的角岩中,受构造和岩浆岩控制明
In 1984, when studying the ore composition of the Guangxi tinfield polymetallic deposit in Guangxi, the author found two kinds of minerals, antimony-natural bismuth and natural bismuth-antimony solid solution series that have not been reported at home and abroad Bismuth - natural antimony. At the same time, the first domestic antimony-bismuth iron ore was also found, which is almost identical to that of a copper-iron deposit in Italy. Their discovery not only expanded the mineralization of the tin deposits, but also has the research significance of mineralogy, geochemistry and mineralogy. First, the geological production of the mine for the tin polymetallic deposits. The main ore bodies are veins and reticulate veins like two layers. The orebodies are produced in the mid-Devonian Nanobiao Formation of the Anticline and its two wings and some shallow marine clastic rocks and their metamorphosed hornfels in the Lo Wu Formation, controlled by tectonism and magmatic rocks
