✦ Synopsis


A number of concentrates of vitrinite, liptinite and inertinite groups of macerals, prepared and sealed under nitrogen by Fenton and Smith, have been made availableto us. They are being studied in a number of institutions using various techniques. The set comprises seven vitrinites, four liptinites and eight inertinites, the last-named including some reputed semifusinite concentrates. Identifications of seams and sample history are provided here, together with chemical analyses and re-analysis of petrographic compositions using reflected light methods. The vitrinites cover a range of rank represented by carbon contents from 81.5 to 91.4%dmmf (hvB to Iv). The liptinites consist very largely of sporinite. Dilatation tests indicate that little if any weathering has occurred during 20 years of storage of the vitrinites.
