Given below are types of “plutonic, or intrusive, igneous rocks” found in Himalayas. Select the one that is not a type of the “plutonic, or intrusive, igneous rocks”. Correct Answer Alunite

  • Alunite is not a type of the “plutonic, or intrusive, igneous rocks”.
  • It is a type of extrusive igneous rocks found in the Himalayas.
  • The rocks that are formed as a result of cooling or solidifying of lava or magma, are termed as Igneous Rocks.
  • These are of two types:
  • Volcanic/extrusive rocks (Formed by cooling of molten magma on the surface of the earth. E.g. Basalt)
  • Plutonic/intrusive rocks (Formed by the magma that cools and solidifies inside the crust of the earth. E.g. Granite)
