Slow cooling rock
WebbIf magma is trapped underground in an igneous intrusion, it cools slowly because it is insulated by the surrounding rock. Crystals have more time to grow to larger size. In smaller intrusions, such as sills and dykes, … Webb24 sep. 2024 · The rapid cooling doesn’t allow large crystals to form. How cooling rate affects the formation of igneous rocks? The texture of an igneous rock (fine-grained vs coarse-grained) is dependent on the rate of cooling of the melt: slow cooling allows large crystals to form, fast cooling yields small crystals. They cool too quickly to form crystals.

Much of the Earth's oceanic crust is made of gabbro, formed at mid-ocean ridges . Gabbro is also found as plutons associated with continental volcanism . Visa mer Gabbro is a phaneritic (coarse-grained), mafic intrusive igneous rock formed from the slow cooling of magnesium-rich and iron-rich magma into a holocrystalline mass deep beneath the Earth's surface.
