Abstract

This vacuum-assisted technique for colored impregnation of all rock types clearly defines porosity, even in low-permeability, very fine grained, or semifriable material. The technique is also suitable for use with water-soluble and heat-sensitive material. The technique is trouble-free and provides a practical way of visually reproducing rock pore space less than 1 μm in size.
