What are the parent rocks of gabbro?
Gabbro is an igneous rock, and therefore does not have a parent rock as would a metamorphic rock. Gabbro is an intrusive igneous rock formed from the slow cooling and solidification of mafic magmas deep underground.
Is gabbro a felsic rock?
No, gabbro is not a felsic rock. Gabbro is classified as a mafic rock due to its dark color and high content of iron and magnesium minerals, while felsic rocks are light-colored and have a higher silica content.
What are some examples of intrusive igneous rock?
Granite and gabbro are the two biggies, granite being formed underground by felsic magma, and gabbro being formed underground by mafic magma. Diorite and peridotite are two others.
What igneous rock has no visible crystals?
Granite is a coarse grained igneous rock without Pyroxene.
What is the Mohs hardness of obsidian?
Strictly speaking obsidian is not a rock as it is not composed of crystals so can't be mineralic! It is technically a volcanic glass. It's Moh's hardness is approximately 5-6 according to the Wikipedia entry for Obsidian although an exact value would depend on the exact composition of the Obsidian in question.
Would gabbro or obsidian make a better arrowhead?
Obsidian
What is example of igneous rock?
Basalt and pumice.
What rock form from molten?
Rocks formed from solidified molten rock are classified as igneous rock. Examples would be basalt, granite, gabbro, pumice, obsidian, and rhyolite.
What clasts would you obtain if you crushed gabbro?
If you crushed gabbro, you would obtain clasts primarily composed of minerals such as pyroxene, plagioclase feldspar, and olivine. These minerals are common in gabbro, which is a coarse-grained igneous rock primarily made up of these mineral components.
What are the parent rocks of gabbro?
Gabbro is an igneous rock, and therefore does not have a parent rock as would a metamorphic rock. Gabbro is an intrusive igneous rock formed from the slow cooling and solidification of mafic magmas deep underground.
Is gabbro a felsic rock?

Will obsidian flake in your hand?
Obsidian is a natural glass that can form sharp edges when broken, known as obsidian flakes. However, whether it flakes in your hand would depend on the force applied and the specific condition of the obsidian. Generally, obsidian will flake if enough pressure is applied to break it.
What is 1 example of an igneous rock?
Any rock that erupted on (lava) or within the Earth or crystallized from molten rock (magma). Such rock would fall into two categories: Intrusive (crystallized within the Earth), granite, gabbro, diorite, pegmatite, peridotite and extrusive (erupted and crystallized on the surface) rhyolite, andesite, obsidian, basalt, tuff and pumice.
Could carbon-14 be used to date a stone arrowhead found at an ancient burial site?
A:Carbon-14 dating could not be used directly from the arrowhead itself. However, the bones associated with the arrowhead could be dated by this method, if they are sufficiently recent for this method. If the arrowhead is properly associated with the bones, you would then know its age.
Which is older a gabbro dike or a gray shale?
A gabbro dike is typically older than a gray shale. Gabbro is an igneous rock that forms from the cooling of magma intruding into existing rock formations. Gray shale, on the other hand, is a sedimentary rock that forms from the accumulation of sediment over time. Therefore, the gabbro dike would have formed before the gray shale was deposited.
Will someone start a server on Terraria and give me an Obsidian Skull?
Anyone can give anything on a server and you would get to keep it, just begging people for it is hard, but the obsidian skull is not hard to make. Only 30 obsidian.
If you were a rock which rock would you be using your personality?
