The end of the Late Palaeozoic Ice Age (LPIA) was characterized by the development of widespread peat-forming mires across Gondwana concurrently with the evolution of the Glossopteris- flora. The Aramac Coal Measures in the Galilee Basin of Australia represent some of the early phase of humic peat formation following the deglaciation in an ameliorating climate. This work aims to examine two boreholes using a multidisciplinary approach involving palynology, coal petrology, carbon isotope geochemistry and biomarkers to reconstruct the climate, environment and floras of this post-glacial period. Palynostratigraphy suggests a late Artinskian to early Kungurian age for the Aramac Coal Measures separated from the overlying JK seams by an unconformity.
