Answers
Answer:‘Crystalline igneous rocks’ is usually used as a general term for any variety (or several varieties) of (typically) intrusive igneous rocks, generally.
So the term in that sentence would refer to granites, diorites, gabbros or whatever kinds of intrusive igneous rock units occur in the east and southern Deccan plateau.
Such rocks tend to have reasonable amounts of iron - particularly the more mafic varieties like diorite and gabbro - and in any warm environment, the iron in the minerals of those rocks will oxidize forming iron oxides, which are often very red.
Soil develops by chemical and mechanical weathering and erosion of rocks, therefore soils developed on iron-bearing rocks are frequently red or orange.
