Chemically and mieralogically it appears to be a true granite but with its finer grain size (often under 0.25mm) it is nearer to an intermediate rock such as a felsite.The consensus is that this sort of rock being a more acid type,is a later differentiation and intrusion.Why are lava flows typically finer grained than intrusive These rocks are cross-grained due to they have a slow cooldown time.One can easily identify the rocks as they are coarse and have large particles.Extrusive igneous rocks,on the other hand,are made from lava and formed on the surface of the Earth.Because of this phenomenon,these rocks cool more quickly than the intrusive rocks as they are What are coarse-grained igneous rocks? - QuoraJan 14,2017 fine grain definitionlimestoneigneous rockscoarse#0183;Coarse-grained igneous rocks (igneous tocks with large crystals) are usually formed at some depth beneath the surface.At depth,the difference in temperature between the molten rock material and its surroundings is relatively small,so this let's the molten material cool more slowly.The low cooling rate allows large crystals to form.
