1.decan trap is a basic rock where as basement having acidic composition.
2.in case of basement feldspar content is more.
3.deccan trap is a extrusive viscious rock.
basement rocks are more stronger than that of Deccan traps.
hard basalt rock of deccan trap
Fine aggragate=smaller, smoother rocks Course aggragate= larger, rougher rocks
Deccan Plateau are pre-Cambrian Blocks. Formed around 600 million year ago.Plateau formation start when there was no life on earth(On Geological Time Scale 4 billion year ago).They under went various changes like Volcanic Irruptions, Erosion etc. Dharwaar Rocks are most famous Deccan rock of India,rich in minerals. Hence Deccan Plateau have Igneous-Rocks as well as Sediments Rocks!

You can find metamorphic rocks in India along the Deccan Traps border. Igneous and sedimentary rocks can also be found there.
Supracrustal rocks are those sedimentary or volcanic rocks deposited or formed over the basement rocks which were later metamorphosed.
All rocks are made up of many small crystals linked together. These crystalline rocks have an ordered and repetitious internal chemical structure), so they display the properties of crystals. (Smith) In geology, the terms basement and crystalline basement are used to define the rocks below a sedimentary platform or cover, or more generally any rock below sedimentary rocks or sedimentary basins that are metamorphic or igneous in origin. The basement is composed of hard crystalline or re-crystallized rocks such as granites, basalts, metaquartzites, or gneisses.
