Hyderabad Rock Formations (Gneiss and Granite)

Hyderabad – situated in India is part of the Deccan plateau. The area is full of spectacular rock formations – toadstools, mushroom rocks, hanging monsters, and turtle back. These rocks were formed probably 2.5 billion years ago.

Earth formed about 4.5  billion years ago. The surface of the Earth solidified about 3.5 billion years ago (when water too appeared as seas). About 2.5 billion years ago, some molten magma oozed on to the surface (Earth crust) in typical “Deccan lava flow” fashion. Much molten magma however probably pushed up the crust but cooled beneath the crust (which could have been thicker then due to lesser time of weathering) unable to push anymore.  The magma formed granitic domes, sheets, and stocks or massive intrusive batholiths.

Later through Precambrian and Cambrian the crust underwent weathering and eroded exposing the Granite beneath. The Granite developed horizontal and vertical cracks and were weathered to their present spectacular forms.
