Thin sections, impregnated with blue epoxy to highlight pore space, provide information on texture (grain size, sorting) grain composition, intergranular phases and pore types.  Modal analysis data (point count) quantifies each of the rock and pore space components as a percentage of the rock volume.

Fluorescent light microscopy uses an auto-fluorescing epoxy to help identify pore space not large enough to be visible during standard thin section evaluation.  This "microporosity" can be present in altered grins, intergranular clay and very small remnants of intergranular pores.
