What is the Size of granite grain?
Granite is considered a coarse grained rock.
What grain size is marble.?
2.34971 gigabites. =) iloverin. <3 ? I believe the asker was referring to fine-grained or coarse-grained.
How fast do coarse grained and fine grained rocks cool?
If the rocks are igneous then in general:- Coarse = slowly. Fine = fast. However if the rocks are metamorphic or sedimentary then grain size has nothing to do with cooling and indicates other things.
What is Grain size of metamorphic rock?
It varies some metamorphic rocks are fine grained (eg slate) and others have very large crystals (eg an augen gneiss).
What is basalt's grain size?
Basalt's grain size is considered to be super-fine and very smooth.

What are the grains of a rock-?
Grains: Grains that are not crystals in rock do not have flat shiny faces. They are rounded, like grain of sand, or jagged, like a piece of broken rock. Grain Size: Grain size in rocks can mean the size of crystal grains or of fragments: Coarse Grained: most of the rock is made of grains as largeas rice, or larger.

What is the difference between fine and coarse grained igneous rock?
Coarse grained textured rocks (phaneritic) have very large crystals because the magma, from which they are created, cools very slowly. Fine grained rocks (aphaneritic) have small crystals because the lava, from which they are created, cools down very quickly.
Does obsidian a glassy rock have a large grain size or a small grain size?
Actually, obsidian doesn't have grains at all. Technically obsidian is a glass, which means it has no internal structure. When geologists refer the the grain size of a rock, they mean how big the crystals that make it up are. Since obsidian has no crystals, it therefore has no grain size.
