Answer:
he larger the crystals and the more mafic the composition
Explanation:
Temperature at which minerals crystallize can determine the nature of composition of the rock and the crystal sizes.
- When a magma crystallizes at high temperature, the mineral grains have enough time to aggregate around a nuclei.
- This makes the sizes big.
- Mafic minerals are know to crystallize at high temperatures.
- Felsic minerals differentiate at low temperatures.
