How are crystals different to grains
WebInitially in the casting process, small crystals form at the mould wall. This is because heat is conducted away through the mould walls and therefore the liquid next to the mould wall solidifies first, and also because nucleation … WebA phenocryst is a large crystal that visually stands out compared to the rest of the minerals. Phenocrysts are found in porphyritic textures where large grains are visible in volcanic extrusive rocks.
