| 中文摘要: |
| 本文探讨了佰强金、多金属矿田Rb-Sr、Pb-Pb及S、O、H同位素地质特征;成矿物质的多源性;分析了它们与五台花岗-绿岩区的渊源关系;阐述了成矿溶液中的水主要来自大气降水的事实;提出了佰强矿田的金、多金属矿床是受燕山早期次火山岩控制的,再造绿岩型金、多金属矿床的认识. |
| 英文摘要: |
| The ore field is a Au-Ag-Pb-Zn-Mo poly-metal ore field situated in the middle part of Wutai granite-greenstone tarrain. Results of Rb-Sr, Pb-Pb, S, O and H isotope analysis reveal that ore material is poly-sourced but dominated by lower crust material. And ore fluid is mainly composed of meteroid water.On the basis of analysing geological features of Wutai granite-greenstone tarrain and evolution of Pb-Pb and S isotopes the author considers the ore field to be a reworked greenstone belt Au-poly-metal ore field formed in the Early Yanshanian Period through superpositions of several metallogenesises since Pre-cambrian. |
