Deccan Traps - Chemical Composition

Chemical Composition

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)

    The naive notion that a mother naturally acquires the complex skills of childrearing simply because she has given birth now seems as absurd to me as enrolling in a nine-month class in composition and imagining that at the end of the course you are now prepared to begin writing War and Peace.
    Mary Kay Blakely (20th century)
