导言本项研究是关于斑铜矿—黄铜矿连晶的出溶结构,因为这种组合在铜矿床中是普遍出现的,而且许多这类的组合被解释为出溶结构(Brett 1964,Ramdohr 1969)。如果把这些自然产出的结构与之在受控制的实验条件形成的结构比较,就能够更好地了解它们的成因。Schwatz(1931a)曾经在这方面作过努力。他使用密封的但是没有抽成真空的硼硅酸玻璃试管,用自然产出的斑铜矿—黄铜矿共生组合使之在高于475℃的温度下均一化,再让它
INTRODUCTION This study deals with the dissolution structures of tetragonal-chalcopyrite brazes, as this assemblage is prevalent in copper deposits and many of these combinations are interpreted as dissolution structures (Brett 1964, Ramdohr 1969). If one compares these natural-output structures with structures that result from controlled experimental conditions, one can better understand their causes. Schwatz (1931a) has worked hard in this area. Using a sealed, but not evacuated, borosilicate glass tube, he homogenized it with a natural bornite-chalcopyrite symbiosis at a temperature above 475 ° C
