| 英文摘要 | There are four types of gold deposits in East Shandong: 1) altered breccia-type along basin-marginal faults, 2) porphyryepithermal type, 3) quartz vein type, 4) altered tectonite-type. Systematical research on C-O and Sr-Nd isotopes of carbonate minerals in the four deposit types was carried out. This research demonstrates that, corresponding to geological settings and features of the gold deposits, there might be two ore-forming fluid systems, namely, magma-affinitive and basin-affinitive. The former one is related to porphyry-epithermal type, quartz vein type, and altered tectonite-type, the later one is related to altered gold-bearing breccia-type along basin-marginal faults. They show different C-O and Sr-Nd isotopic characteristics. Carbonate minerals from the magma-affinitive gold deposits manifest similar Sr-Nd isotopic features as the coeval mantle-derived igneous rocks in Shandong, and their carbon isotope compositions exhibit characters of mantle-derived or magma-derived carbon. Their oxygen isotope compositions imply possibility of mixing from primary water and meteoric water. All these together suggest that the ore-forming fluids principally carried characteristics of metal-rich mantle fluids that were probably diluted by circulated meteoric water as the ascending mantle fluids reached the upper part of the crust. The basin-affinitive gold deposits, on the other hand, contain carbonate minerals whose C-O and Sr-Nd isotopic compositions are typically heterogeneous, characteristic of ore-forming fluids resulted from circulating and heated meteoric water that obtained ore-forming materials mainly from fluid-rock interaction during its circulation in the upper part of the crust. |
