Alignment marking for rock sample analysis

摘要

A method for using a Focused Ion Beam and/or Scanning Electron Microscope (FIB/SEM) for etching one or more alignment markers on a rock sample, the one or more alignment markers being etched on the rock sample using the FIB/SEM. The one or more alignment markers may further be deposited with a platinum alloy or other suitable compositions for increasing alignment marker visibility.

1. A method of analyzing a rock sample in one or more analysis devices, the method comprising:
installing the rock sample in the one or more analysis devices; identifying a localized region of interest and a global region of interest encompassing the localized region of interest on the rock sample in the one or more analysis devices; performing global marking by aligning the rock sample to the global region of interest in the one or more analysis devices for marking and etching one or more global of alignment markers on the rock sample relative to the global region of interest using the one or more analysis devices; and performing localized marking by aligning the rock sample to the localized region of interest encompassed in the global region in the one or more analysis devices for marking and etching one or more localized of alignment markers on the rock sample relative to the localized region of interest using the one or more analysis devices.
