| 中文摘要: |
| 以美国亨德森斑岩钼矿为例,从地球化学、矿物学等多角度剖析了斑岩矿床体系中流体演化的过程.成矿流体随时间从高温向低温演化,不同的阶段有不同的矿物组合发育形成,不同的元素在流体地球化学演化途径中的化学行为也不尽一致.体系中不同部位的流体地球化学演化途径遵循一个大的方向和规律,但某些阶段也有所差异,这种差异可能是由流体的不同成分和侵位深度、流动方向不同引起的. |
| 英文摘要: |
| Taking American Henderson porphyry Mo deposit as an example the author analyzes fluid evolution process of the ore-forming system from aspects of geochemistry,mineralogy etc.The ore fluid evolved temporally from high to low temperature with different mineral assemblages developed in different evolutionary stages and behavior disparity of different elements in the evolutionary way.The geochemical evolution way of fluid in varied sections followed roughly the same direction and pattern but differences occurred in certain stages due to variation of the fluid composition,emplacement depth and flowing direction. |
