Proterozoic Granitoids of Rajasthan
Journal of the Geological Society of India, 2005Abstract Two granitoid bodies each from Palaeo-, Meso- and Neo-proterozoic periods have been studied for their chemical, petrological and source characteristics The Proterozoic granitoids are megacrystic as well non-megacrystic with variable effect by tectonometamorphic events The Palaeo-proterozoic granitoids are peraluminous ...

Abstract Assessment of current Proterozoic palaeomagnetic data and the assumptions necessary for applying them to tectonic problems shows that first order tectonic phenomena (involving the creation and/or destruction of Atlantic-sized oceans) should now be detectable. Although lesser relative motions are difficult to prove or disprove
