摘要
云浮硫铁矿产于震旦系海相碎屑沉积岩中，属华南型块状硫化物矿床，稀土、δ（１８Ｏ）、δ（３４Ｓ）及铅同位素等显示，该矿床为上地壳物质来源，但其条带状黄铁矿与块状黄铁矿石的形成环境存在着很大的差异．矿床成因与喷流作用有关，微生物对成矿起了一定的作用。
Yunfu pyrite deposit is located in clastic sedimentary rocks in Sinian system, and belongs to South China type of massive sulfide deposits. The characteristics of REE and isotope composition of δ( 18 O),δ( 34 S) and lead show that the ore deposit is derived from upper crust, but its forming surroundings of belt ore is different obviously from the massive pyrite ore. Metallogenic genesis of the deposit has relation to the sedimentation exhalation. Microbe give the role to the mineralization, especially to the concentration of scattered metal elements.
