Introduction The Earth’s lithosphere is its rigid outer shell, which rests on the more fluid asthenosphere. The thickness of the lithosphere varies, from a few kilometers at ocean spreading centers to 250-300 kilometers within continental cratons. There are two significant seismic boundaries in the crust and upper mantle: the Mohorovicic »
This post is a summary of the interesting paper on the geodynamic relationships between Paleozoic arc development along the flanks of the interior (e.g. the Iapetus and Rheic) oceans and the exterior Paleopacific Ocean. Murphy, B., van Staal, C and Collins, W, A comparison of the evolution of arc complexes »
Just received the above titled book from Elsevier for review. I had the great pleasure of spending some time in the field in Myanmar with Andrew Mitchell in 2017 and this important contribution by him is a remarkable testament to his life’s work. He has enormous knowledge of the geology »
Gondwana Research 48 (2017) 257–284: Read Here Wolfgang Franke, L. Robin M. Cocks, Trond H. Torsvik The Variscan and related North American orogenies which now total 6,000 kilometres of strike, were caused by the opening and closing of the Rheic Ocean over a 100 million year period from 440MA to 320MA.

Chris Harrison from Department of Marine Geosciences, Rosenstiel School of Marine and Atmospheric Science, University of Miami in a paper in Earth, Planets and Space has sought to resolve the question of the number plates that make up the surface of the earth. The number of tectonic plates on Earth described »
