The Olivine normally crystalizes first from the magma of the mafic minerals, It crystalizes at between 1200°C and 1300°C. when the temperature of magma drops and there is a silica still remains in the magma so the olivine reacts with this silica to form pyroxene.and by more cooling of the temperature of magma and there is a silica still remains in magma pyroxene change to amphibole, and amphibole to biotite.when the pyroxene strat to form the plagioclase feldspar also forms.

Answer:
Metallic bonding is found in metals and their alloys. When the atoms give up their valence electrons, they form ions. These ions are held together by the electron cloud surrounding them. Metals are shiny because they have a lot of free (i.e. delocalized) electrons that form a cloud of highly mobile negatively charged electrons on and beneath the smooth metal surface in the ideal case. ... In the absence of any external EM field, the charges in the plasma are uniformly distributed within the metal.
Explanation:
In metallic bonding, the electrons are “surrendered” to a common pool and become shared by all the atoms in the solid metal.
