| 摘 要： | 流体包裹体岩相学和显微测温学研究表明，银山矿床石英斑岩和金金属矿床中都发现须含石盐的高盐度流体包裹体，表明至少在成矿作用的早期成矿流体为高盐度流体，高盐度流体不是由热水溶液的不混溶作用或沸腾作用形成的，而是直接从饱和水的结晶岩浆熔体中出溶的，银山矿床的成矿流体与斑岩铜矿的成矿流体具有相似性，证实矿床深部可能有隐伏斑岩铜矿。

| Abstract: | The fluid-inclusion study at the Yinshan polymetallic ore deposit reports the presence of liquid- and vapor-rich, two-phase inclusions and liquid-rich, high-salinity inclusions containing hilite. This indicates that ore-forming fluid at early stage of ore-forming processes could have been high salinity fluid. Fluid-inclusion observations and microthermometric data suggest that this saline fluid was not generated by aqueous fluid immiscibility or boiling. The high salinity fluids are best interpreted as being generated directly from a water-saturated crystallizing magmatic melt. The ore-forming fluid of the ore deposit and that of porphyry copper ore deposit are similar in characteristics. It is confirmed that there is a concealed porphyry copper deposit at the depth of the Yinshan deposit. |
