Summary

A revised reconstruction of Gondwana is presented. It is based on previous reconstructions that were geologically well constrained and utilizes marine magnetic anomalies and recent paleomagnetic results as additional constraints. Three areas of conflict, 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 prebreakup components. Poles and angles of rotation were determined directly from the terminal for optimal geometric fit.
