Objectives
The Identification of Dispersed Organic matter working group (IDOM WG) was created in Budapest (2004) upon revision of the activities of the former Isolation of Sedimentary Organic Matter WG (1988-1998). The focus of this WG is to test the applicability of the existing nomenclature of dispersed organic matter classified in accordance to the ICCP-TSOP Classification System (2004). To address difficulties arising from the use of different nomenclatures within the Isolation of Sedimentary Organic Matter WG, the liptinite maceral group was chosen to test the identification of alginite and bituminite in sedimentary rocks.
The activities of the WG are comprised of round robin exercises with the aim of identification of dispersed organic matter (bituminite, alginite, etc.) on digital images by application of ICCP definitions enclosed in the Handbook of Coal Petrography, 3rd supplement to the 2nd edition (1993).
