Revised Reconstruction of Gondwana (Paleoceanographic Mapping Project Report No. 04-0885)

A revised reconstruction of Gondwana is presented. It is based on previous reconstructions that were geologically well constrained as well as utilizing marine magnetic anomalies as additional constraints. Three areas of conflicts, namely the position of Madagascar, the location of India/Sri Lanka an...

Description
Summary:A revised reconstruction of Gondwana is presented. It is based on previous reconstructions that were geologically well constrained as well as utilizing marine magnetic anomalies as additional constraints. Three areas of conflicts, namely the position of Madagascar, the location of India/Sri Lanka and the overlap of the Antarctic Peninsula with the Falkland Plateau are discussed. An interactive graphics terminal was used to minimize continental overlap while reducing obvious gaps between pre-breakup Gondwanide components. Poles and angles of rotation were determined directly from the terminal for the optimum fit. UT Institute for Geophysics Paleoceanographic Mapping Project (POMP) Institute for Geophysics
