What material is most abundant in oceanic crust?
Mafic igneous rock, predominately gabbro and its fine-grained equivalent, basalt.
Is quartzite course grained or fine grained?
it is coarse grained
What is meaning the grain of the rock?
fine grained or coarse grained
What is a dark coarse-grained intrusive igneous rock similar to basalt in mineral make up?
Gabbro
What is the difference between fine-grained and coarse-grained atomic actions?
A Fine-grained atomic action is one that can be implemented directly by an indivisible machine instruction. A coarse-grained atomic action is a sequence of fine-grained atomic actions that appear to be indivisible.
Is basalt the fine-grained equivalent of gabbro?
Yes, they both have a mafic composition.
What material is most abundant in oceanic crust?
Mafic igneous rock, predominately gabbro and its fine-grained equivalent, basalt.
In what way is gabbro different from basalt?
Gabbro and basalt are both igneous rocks. However, gabbro is an intrusive rock, and basalt is an extrusive rock.
How is basalt different from gabbro?
Basalt is an Extrusive Igneous Rock, it is a fine grained textured rock, While Gabbro is an Intrusive Igneous Rock and it has a Coarse grain texture.
Is shale fine-grained or coarse-grained?
shale is fine grained
What do granite and gabbro have in common?
They are both coarse grained intrusive igneous rocks
What is a dark fine grained rock called?
They are rocks formed from lava at or near the surface. Basalt is a typical fine-grained extrusive igneous rock, composed of mineral crystals that require magnification to see. The fine-grained texture is due to rapid solidification of the lava which leaves little time for large mineral crystal formation.
Is obsidian course-grained or fine-grain?
fine grained
What is the difference between coarse-grained and fine-grained?
Fine grained has larger crystals and coarse grained has smaller crystals
What is the difference between fine-grained and coarse-grained?
Fine grained has larger crystals and coarse grained has smaller crystals
Why does Granite take much longer to form than Basalt?
hmmm, granite is intrusive, formed and cooled slowly at depth with larger individual crystals. Basalt is extrusive, fine grained (small crystals and cooled quickly. The intrusive equivalent of basalt is gabbro. For granite; rhylolite
Where can you find gabbro?
Gabbro is a group of dark, coarse-grained, intrusive mafic igneous rocks. They are often found beneath the Earth's surface where they form into crystals.
