The Precambrian-cambrian Boundary Problem: Paleomagnetic Directions from the Amadeus Basin, Central Australia
Late Precambrian to early Cambrian sediments of the Amadeus Basin, Central Australia, contain two stable directions of magnetization. Lithologies are diverse and include red beds, green beds, and carbonates, all of which respond to thermal cleaning. Positive fold and unconformity tests, and a well-defined polarity zonation reveal the primary component and direction of magnetization. This direct...
متن کاملAmerican Journal of Science CONSTRAINTS ON NEOPROTEROZOIC PALEOGEOGRAPHY AND PALEOZOIC OROGENESIS FROM PALEOMAGNETIC RECORDS OF THE BITTER SPRINGS FORMATION, AMADEUS BASIN, CENTRAL AUSTRALIA
The supercontinent Rodinia is hypothesized to have been assembled and positioned in tropical latitudes by the early Neoproterozoic Era. Paleomagnetic data from limestones of Svalbard and basaltic dikes of South China have been interpreted to record rapid changes in paleogeography driven by true polar wander that may have rotated the supercontinent in association with the 800 Ma Bitter Springs c...
متن کاملModal Decay in the Australia–Antarctic Basin
The barotropic intraseasonal variability in the Australia–Antarctic Basin (AAB) is studied in terms of the excitation and decay of topographically trapped barotropic modes. The main objective is to reconcile two widely differing estimates of the decay rate of sea surface height (SSH) anomalies in the AAB that are assumed to be related to barotropic modes. First, an empirical orthogonal function...
متن کاملPetroleum System of the Gippsland Basin, Australia
The Gippsland Basin Province 3930, located on the southeastern coast of Australia, is formed from two successive failed rifts that developed into a passive margin during the Cretaceous. Formation of this basin is related to the break up of Gondwana, which resulted in the separation of Antarctica from Australia, and the separation of the New Zealand and Lord Howe Rise continental crust from Aust...
