Which Igneous Rocks Have Large Crystals at Jared Stoddard blog

Which Igneous Rocks Have Large Crystals. They often have a crystalline texture due to the interlocking of crystals that form as the. Igneous rocks are formed from the solidification of magma, which is a hot (600 to 1,300 °c, or 1,100 to 2,400 °f) molten or partially molten rock material. Rocks can have this texture, and. Igneous rocks are characterized by several distinct properties: The larger crystals are called phenocrysts , and the smaller ones are referred to as the groundmass. However, the larger crystals must be easily noticed and distinguishable. Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the earth or while the melted rock is still inside the crust. An igneous rock with crystals of distinctly different size (figure 7.14) is said to have a porphyritic texture, or might be referred to as a porphyry. Earth is composed predominantly of a large mass of igneous rock with a very thin veneer of weathered material—namely, sedimentary rock.
