Present Thermal Status of Indian Lithosphere

Abstract

The estimation of surface heat flow for Indian province is based on the temperature measured from the shallow borehole. Such estimation of surface heat flow is not very reliable for deep-seated Numerous workers have given various empirical relations bctwccn surface heat flow, crustal and lithospheric thicknesses. relations give more realistic information about the global regimes. In the present paper, we discuss the lithospheric thickness obtained from the magnetotelluric studies for Indoand Peninsular regions with measured heat flow data in the region The lithospheric thickness and the heat flow of various parts of Indian regions has been compared with other regions of the world. The study shows that Indo-Gangetic basin has heat flow values compared to the basins found in other parts of world Peninsular regions of India show similar heat flow values as been observed in other stable shield provinces.
