Microbeam analysis of rock micropores Focused ion beam-scanning Electron Microscope Three-Dimensional Imaging Analysis Method

1 Scope

This document specifies a method for three-dimensional imaging of microporosity in dense rocks using focused ion beam-scanning electron microscopy. This document is applicable to micro-nano pores of 50nm~20μm in rocks such as mudstone, shale, dense carbonate rock, dense sandstone and coal rock. Analysis of other geological samples shall be carried out in the same manner.
