摘要
叙永两河口硫铁矿位于巨型火山—沉积型硫铁矿矿床之中,矿石矿物以黄铁矿为主,脉石矿物以高岭石为主。矿石以结晶粒状、板柱状结构为主,次为豆状、鲕状、放射状结构,具有树枝状、似脉状、结核状、星点状构造四种主要构造。成矿作用主要包括陆源碎屑作用、生物碎屑作用、胶体化学作用、交代作用、重结晶作用、次生淋滤作用及氧化水解作用等。
Xuyong Lianghekou pyrite is located in the giant volcano-sedimentary pyrite deposit. Ore minerals are mainly pyrite, gangue minerals are dominated by kaolinite. Ore structure mainly include crystalline granular and plate column, a few lenticular, oolitic, radial. Ore construction includes dendritic, like a vein, concretionary, star. Mineral genesis consists of terrigenous clastic, bioclastic, colloid chemistry, metasomatism, recrystallization, secondary leaching and oxidation hydrolysis etc.
