广东马口黄铁矿矿床是粤北地区众多黄铁矿矿床之一的中型矿床,对其成因研究前人做了很多工作。随着对客观认识的不断深化,曾有岩浆热液、沉积改造(岩溶、构造改造)、沉积再造(交代)、层控沉积同生“再沉积”等不同认识。我们通过对矿石特征经宏观和镜下观察以及对硫同位素资料的分析之广认为该矿床是在多种作用下进行的,它经历了以沉积—成岩,区域变质—构造改造为主的和热液迭加及表生变化等成矿作用而形成的,属沉积—改造型的层控矿床。
The pyrite deposit in Guangdong is a medium-sized deposit that is one of the many pyrite deposits in northern Guangdong. Much work has been done on the genesis of its predecessors. With the continuous deepening of objective understanding, there have been different understandings of magmatic hydrothermal fluids, sedimentary alteration (karstification and tectonic remolding), sedimentation reformation (explanation) and stratigraphic sedimentation co-occurrence of “redeposition”. Based on the macroscopic and microscopic observation of ore features and the analysis of sulfur isotope data, we believe that the deposit was under various functions and has undergone a combination of depositional-diagenesis, regional metamorphism-tectonic remodeling and heat Liquid superposition and epigenetic changes such as mineralization formed, is a sedimentary - remodeling of stratabound ore deposit.
