Abstract

A suite of Permian Gondwana coals from southern Africa, exclusive of the Republic of South Africa, were examined petrographically. With the exception of a single low volatile bituminous/semi-anthracite coal from Mozambique, the coal rank is high volatile bituminous C. Most coals were dominated by inertinite-group macerals, primarily semifusinite and detrital inertinite (inertodetrinite), but with significant secretinite in some cases. Vitrinite-group macerals were absent in several Zambian coals. When considering these coals, it becomes apparent that not all Gondwana maceral types determined necessarily fit the ICCP definitions.

Bibliographical note

Funding Information:
In this paper coal macerals from southern African samples (excluding South Africa), acquired by the United States Geological Survey (USGS) as part of their World Coal Quality Inventory project ( Tewalt et al., 2010 ), are considered. The samples originated from Botswana, Mozambique, Tanzania, and Zambia, and are indicative of coals in the region, but are certainly not exhaustive. Generation of petrographic data for these samples was supported by Cooperative Agreements 07ERAG0015 and G10AC00464 from the USGS .
