WebGranitic dykes and pegmatites are well-known examples of granitic rocks that formed when cooling was more rapid than the cooling of a pluton. Also, large fine-grained rhyolite bodies show that coarse-grained texture does not necessarily form when cooling is slow within them. Crystal size depends on many factors, including nucleation rate ... WebDue to slow cooling the crystals grow to large size and have approximately same size. The colours and shape depend on the composition of magma and the minerals that form while cooling. The average granite which has grains 3 to 5 millimetres in diameter is a good example. ii. Aphanitic Texture: This is the texture of an extrusive rock.

WebA pluton is an igneous intrusive rock body that has cooled in the crust. When magma cools within the Earth, the cooling proceeds slowly. Slow cooling allows time for large crystals to form, so intrusive igneous rocks have visible crystals. Granite is the most common intrusive igneous rock (see figure 2 for an example). WebMar 13, 2016 · One is intrusive and the other is extrusive. So I'm going to make a general comment and say that a granite is genetically the same (has the same composition) as a rhyolite.
