Sulfur Isotope Studies of Detailed Mineral Parageneses in MVT-Type Pb-Zn Deposits, S. E. MO.: A Test of the Involvement of Multiple Basinal Fluid Sources

成矿流体的来源及其与寄主的相互作用 岩石是相当关注的理解， 密西西比河谷型铅锌矿床。 东南 密苏里州很有可能多个盆地 流体参与，并表明一个更复杂的起源， 硫化物矿体在该地区比以前建模。 这 该项目将利用硫同位素的变化， 多矿区硫化物沉积共生序列 在东南部密苏里州铅锌矿 区的 结果应该澄清连续脉冲的作用 成矿流体及其与围岩的相互作用。

The source of ore fluids and their interactions with host rocks are of considerable concern in the understanding of the Mississippi Valley-type of Lead-Zinc deposits. In southeast Missouri there is a strong possibility that multiple basinal fluids were involved and indicate a more complex origin for sulfide orebodies in the region than previously modeled. This project will utilize sulfur isotope variations throughout the paragenetic sequence of sulfide deposition for a number of mines in the Viburnum Trend of the Southeast Missouri Lead-Zinc district. Results should clarify the role of successive pulses of ore-forming fluids and their interaction with host rocks.
