摘要
对广东官田黄铁矿矿床研究过程中，在该区首次发现多种硫盐矿物，文章对硫盐矿物进行了系统阐述，对矿石组构，主、微量元素特征，矿化期、次进行了研究。通过硫、氢氧同位素、流体包裹体成分等几方面的研究，进而探讨了矿床成因。研究认为，矿床的形成以火山岩浆期后气液为主。
Research on the Guantian pyrite deposit in Guangdong led to the discovery of many sulfate minerals besides pyrite, such as emplectite, aikinite, ourayite, and enargite, totally in excess of ten species. All these species were described with respect to their mineralogical characteristics, and the mineralizing activities in the deposit were grouped into three phases following a comprehensive review of the ore textures as well as features of common and trace elements. Further studies were focused on the genesis of the deposit based on S, H and O isotopes, inclusion homogenization temperatures and other features. It is consequently concluded that the Guantian deposit should owe its formation to the metasomatism at low to intermediate temperatures by the postmagmatic hydrothermal solution along with less meteoric water, suggesting the deposit is a hydrothermal metasomatic vein type one.
