area of Deccan Plateau of India?

Answer 1

The Deccan Plateau is a vast plateau in India, encompassing most of Central and Southern India.

It comprises the whole of peninsular India south of the Vindhya range and has an elevation which ranges from 1,500 to 2,500 feet (450 to 750 m). It is bounded in the west by the Western Ghats and in the east by the Eastern Ghats. These two formations form one of the vertex of a triangle which encompasses the plateau with the Vindhya range forming the third side. This region is one of the most stable land masses of the world.

The vast volcanic basalt beds of the Deccan were laid down in the massive Deccan Traps eruption, which occurred at the end of the Cretaceous period, 65 million years ago. Some paleontologists speculate that this eruption may have caused the extinction of the dinosaurs. Layer after layer was formed by the volcanic activity that lasted many thousands of years, and when the volcanoes became extinct, they left a region of highlands with typically vast stretches of flat areas on top like a table. Hence it is also known as Table Top.

Typically the Deccan Plateau is made up of basalt. This is an extrusive igneous rock. Also in certain sections of the region, we can find granite, which is an intrusive igneous rock. The difference between these two rock types are: basalt rock forms on eruption of lava, that is, on the surface (either out of a volcano, or through massive fissures -- as in the Deccan basalts -- in the ground), while granite forms deep within the Earth. Granite is a felsic rock, meaning it is rich in potassium feldspar and quartz. This composition is continental in origin (meaning it is the primary composition of the continental crust). Since it cooled underground, it has large visible crystals. Basalt, on the other hand, is mafic in composition -- meaning it is rich in pyroxene and, in some cases, olivine, both of which are Mg-Fe rich minerals. Basalt is similar in composition to mantle rocks, indicating that it came from the mantle and did not mix with continental rocks. Basalt forms in areas that are spreading, whereas granite forms in areas that are colliding. Since both rocks are found in the Deccan Plateau, it indicates two different environments of formation.

The Deccan is rich in minerals. Primary mineral ores found in this region are mica and iron ore in the Chhota Nagpur region, and diamonds, gold and other metals in the Golconda region-.
