Crystals that form in slowly cooled magma
WebMagma rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The mold originates deep within the Earth near active plate boundaries or current spots, then increased toward the surface. Igneous rocks are divided into second groups, intrusion or extrusive, dependant upon where the molten rock solidifies.Intrusive Rocks … WebNov 2, 2007 · As magma cools it undergoes reactions that form minerals. The rate of cooling is very important. If the magma cools slowly then the reactions proceed for a longer period of time and the resulting mineral crystals (grains) become large. If the magma cools rapidly then the reactions are much quicker and the mineral crystals (grains) are …
