一、硫同位素特征大鲍庄和罗河两矿区,共分析了79个硫的同位素样品,其中黄铁矿52个、硬石膏20个、水石膏4个、其它样品3个。在79个样品中,大鲍庄矿区为57个,罗河矿区为22个。样品分别采自含矿次火山岩(或经蚀变形成的蚀变岩)、黄铁矿体、硬石膏层、黄铁矿硅化岩及凝灰岩中。有关硫同位素资料见表1、表2和图1。从表1、表2和图1中可以看出大鲍庄和罗 I. CHARACTERISTICS OF SULFUR ISOTOPE The large Baozhuang and Luohe two mines have analyzed 79 sulfur isotope samples, including 52 pyrite, 20 anhydrite, 4 hydrated gypsum and 3 other samples. Among the 79 samples, there are 57 large Daobaozhuang mining areas and 22 Luohe mining areas. Samples were collected from ore-bearing volcanic rocks (or alteration rocks formed by alteration), pyrite bodies, anhydrite layers, pyrite silicified rocks and tuffs, respectively. The sulfur isotope data are shown in Table 1, Table 2 and Figure 1. From Table 1, Table 2 and Figure 1, we can see Baozhuang and Luo
