Research Abstract

A quantitative comparison between the GPS and paleomagnetically determined clockwise rotation suggests that following an initial India-Asia collision a crust of the present Indochina peninsula displaced from paleoposition at 30°N, 94°E by about 1000km during the past 50 million years.
