Fluvial and lacustrine facies in the middle to late Devonian Pertnjara Group, Amadeus Basin, Northern Territory, and their relationship to tectonic events and climate

Journal Article


Abstract


  • The Pertnjara Group consists of a series of lacustrine, braided and meandering fluviatile and alluvial fan deposits which accumulated as a southward thinning wedge in the Amadeus Basin during successive pulses of the Alice Springs Orogeny. Sedimentation of the group started during a pluvial quiescent period following the Late Ordovician Rodingan Movement and deposition of the aeolian Mereenie Sandstone. An uplift event (Pertnjara Movement) in the late Givetian or early Frasnian produced the first wedge of fluviatile sandstone. Growth structures within the basin record movement during some of these tectonic events and help to define the areas affected at each stage. -from Author
