Summary

Coal microlithotypes in seams from the Permian Gidgealpa Group in the Patchawarra Trough of the Cooper Basin are related to the depositional environments prevailing at the time of peat accumulation. Formations which include more than one depositional environment contain coals whose microlithotypes are concentrated into a corresponding number of groups.

Using petrographic analyses, coals which accumulated in a large lake environment can be distinguished from those of the:

(i) lower coastal plain,

(ii) area dominated by coal swamps.

Channel belt coals can be distinguished from those of the:

(i) lower coastal plain,

(ii) upper coastal plain,

(iii) area dominated by coal swamps.

Lower coastal plain coals can be differentiated from those of the upper coastal plain.
