一、引言关于黝铜矿-砷黝铜矿系矿物学的研究,最近十多年来取得了较大进展。首先,由于电子探针微量分析器分析法的确立,现已能报导许多微小部分的化学分析值。其次,对晶体构造进行了探讨,进而对含有黝铜矿的系列作了大量的合成研究,而且还通过差热分析作了研究。可是,与上述研究相比,天然黝铜矿-砷黝铜矿系矿物生成时的物理化学条件却不 I. INTRODUCTION Much progress has been made in the recent ten years on the mineralogy of the tetrahedrite-arsenate-tetrahedrite system. First, many minor chemical analysis values ​​have now been reported due to the establishment of electronic probe microanalysis. Secondly, the crystal structure is explored, and then a large number of synthetic studies have been made on the series containing tetrahedrite, which are also studied by differential thermal analysis. However, compared with the above studies, the physico-chemical conditions of the natural tetrahedrite-arsenite-tin mineral are not
