ABSTRACT

A technique for studying thin sections using both transmitted and incident (reflected) ultraviolet (UV) light has been developed. These two light modes used simultaneously may clearly distinguish pore space, plasma (micromass), and skeleton grains (coarse fraction). For this purpose, either a simple binocular or a petrographic microscope can be used. This technique is complementary to classical methods described in the literature for thin-section analysis and will, at least under conditions discussed here, help alleviate problems encountered in examining thin sections when the skeletal and plasma phases confound porosity identification and measurement.
