摘要：

The analysis of fluid inclusions in minerals holds the key to understanding ore formation processes. PIXE analysis of fluid inclusions using the nuclear microprobe provides a direct non-destructive method to determine the composition of these trapped fluids. However, some results have been controversial. In order to demonstrate the reliability of the PIXE approach, and eliminate spurious sources of important elements, the internal contents of fluid inclusions have been imaged using the new CSIRO-GEMOC nuclear microprobe (NMP) in a method that uses identification and quantitative integration of the inclusion signal from PIXE images. Examples of this approach show clearly the elements that reside within the fluid inclusions, and allow discrimination against solid phases outside and in close proximity to the inclusions.
