Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

And dunite Dunitei if bulk is Forsterite rich and fractional crystallization is taking place. Hazburgite if Equilibrium crystallization with (Fo+En) Orthopyroxinite if bulk is sillica rich and Equilibrium crystallization is going on

Harzburgite and Dunite will form as a result of equilibrium and fractional crystallization in Forsterite-Silica system. Fractional crystallization will lead to the formation of rock containing pure Forsterite (olivine) i.e. Dunite rock. In case of equilibrium crystallization harzburgite will form. Harzburgite is an ultramafic rock which contains olivine (Forsterite in this case) and orthopyroxene (Enstatite in this case).
