Description
Summary:CONTRIBUTION TO the 2nd International Conference on Precambrian Continental Growth and Tectonism (PCGT 2009), held at the Institute of Earth Sciences, Bundelkhand University, Jhansi, India, 24–28 February 2009, Excel India Publishers, New Delhi, 47-49. The expanding Earth view is adopted and palaeogeographical reconstructions are performed adopting a variable radius. In a formerly performed Triassic reconstruction at radius of 3300 km, a new paleoposition of India was found with western margin of India in contact with Antarctica – coasts of Cooperation sea –, India being in northern hemisphere. Then, a check has been performed about the plausibility of the existence of the alleged supercontinent called Rodinia. The results have been that palaeopoles of 750 Ma age indicate continuity of the northern position of India and of its neighbouring fragments, and that all the continents continue to reside in the same mutual position they are today.
