RB 84/00083 Catastrophic Episodes in the Burning of a Coal Seam: Some Explanations of the Occurrence of Pseudo-Igneous Lithologies in the Triassic Sediments of the Springfield Basin - October 1984
Thermally altered argillites and mobilised rocks of anomalous compositions have been attributed to the burning of coal seams in the Triassic succession deposited in the small synclinal 'Springfield' Basin. Some aspects of this explanation appear...-
