    Abstract

    This paper reviews ideas of the Permian-Triassic Gondwana facies as the southern hemisphere component of the Pangean supersequence and its tectonic stages. The Gondwana facies reflects three tectonostratigraphic stages generated by the Pangean heat anomaly. Stage 1 (320-286 Ma, Late Carboniferous) is the stratigraphic lacuna that resulted from the high-standing Pangean platform that initially blocked the escape of heat from the interior. Stage 2 (286-230 Ma, Permian and Early-Middle Triassic) is the first Pangea-wide accumulation of platform sediments in sags and grabens generated by the initial loss of Pangean heat. Stage 3 (230-160 Ma, Late Triassic and Early-Middle Jurassic) is the Pangea-wide rifting that dissipated further heat. Compressive events in Africa, India, and Australia in the mid-Triassic or Carnian (230 ± 5 Ma) correlate with the initial accretion to Eurasia of Cimmeria and the North and South China blocks that marks the maximum coalescence in Pangea. -from Author
