Magma differentiation tends to produce deposits of_______ near the base of intrusions.
A) chromite
B) copper
C) silver
D) gold

Question

Quizplus · Accepted Answer

Chromite is commonly associated with mafic and ultramafic intrusions, which are formed from the crystallization and differentiation of magma. Chromite tends to accumulate near the base of these intrusions due to its high specific gravity and incompatibility with the minerals that crystallize earlier in the differentiation process. Copper, silver, and gold may also be associated with magmatic deposits, but their deposition mechanisms are not solely related to magma differentiation.
