Methods for the petrographic analysis of coals - Method of determining microlithotype, carbominerite and minerite composition not-for-sale including interactions and the need1 Scope This document specifies a method, using a graticule with 20 crossline intersections, for determining the proportions of microlithotypes, carbominerite and minerite in coals. It applies only to determinations made on polished particulate blocks using reflected white light (about 400 nm to 700 nm). Additional blue, blue violet or UV light excitation (365 nm to 440 nm) for better identification of liptinite in fluorescence may be used especially
