Within the Deccan Traps at least 95% of the lavas are tholeiitic basalts, however other rock types do occur:
- Alkali basalts
- Nephelinites
- Lamprophyre
- Carbonatites
Mantle xenoliths have been described from Kachchh (northwestern India) and elsewhere in the western Deccan.

Famous quotes containing the words chemical and/or composition:
“If Thought is capable of being classed with Electricity, or Will with chemical affinity, as a mode of motion, it seems necessary to fall at once under the second law of thermodynamics as one of the energies which most easily degrades itself, and, if not carefully guarded, returns bodily to the cheaper form called Heat. Of all possible theories, this is likely to prove the most fatal to Professors of History.”
—Henry Brooks Adams (1838–1918)
“Modern Western thought will pass into history and be incorporated in it, will have its influence and its place, just as our body will pass into the composition of grass, of sheep, of cutlets, and of men. We do not like that kind of immortality, but what is to be done about it?”
—Alexander Herzen (1812–1870)
