Induced geomagnetic variation and crustal evolution of the southern peninsula of India

The current thinking on crustal evolution and the influence of Precambrian lineaments on tectonism and mineralization provide support for the conjecture that zones of high electrical conductivity exist in the crust which are related to the tectonic and mineralized zones. Studies by the present authors using geological and tectonic data from remote sensing techniques, in particular, together with relevant data on anomalous geomagnetic variations reported in this paper would serve as additional contribution towards the global model.
