Nondestructive method for analyzing total porosity of thin sections

摘要

Total porosity of impregnated thin sections can be measured using X- ray fluorescence. The technique requires an impregnating fluid which contains an element not contained in more than trace quantities by the rock. By measuring the intensity of fluorescence generated by bombarding the impregnated thin section with sufficiently energetic X- rays and rationing that intensity to the intensity of fluorescence generated by subjecting a sample containing only epoxy to the same conditions, and scaling the resulting measures of fluorescence, a measure of total effective porosity is produced.
