Concept of Geospot in Explaining the Source of Geothermal Energy

Tushar Kanti Das

Source of Geothermal energy which plays an important role in governing the different Geodynamical processes, such as,plate motion, volcanism, hotspot, sialic thickening, convective plumes, mantle plumes, volcanic chain, mid-ocean ridge, island arc, polar wandering, is not properly understood still now. Different tenable sources which have been invoked from time to time do not satisfy the exact requirement. As an alternative, we have hypothesized the formation of a strong magnetic field zone in the core-mantle boundary, which is termed as Geospot. The magnetic loops and arches are formed in the D//region situated near the core- mantle boundary due to the growth or decay of a geospot. When a pair of bipolar regions approaches one another, a current sheet is developed, in which magnetic reconnection takes place. As a result, enormous amount of energy is liberated as a consequence of annihilation of magnetic field of geospot.
