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.
What minerals would you expect to find in a sample of gabbro?
Expect to find plagioclase in most phaneritic igneous rocks and often as phenocryts in aphanitic rocks. ... You will also find quartz grains resist scratching with a nail or pocket knife, ... The answer is that in hand samples it is nearly impossible. ... rhyolites while pyroxene occurs in dark-colored rocks like gabbro and basalt).
What would you do if run out of crushed ice to be used for a blend mixing method?
you'll going to use a muddler to crack and crushed ice
Would you be crushed if you were at the center of the earth?
No, I wouldn't be crushed at the center of the Earth. The pressure at the center of the Earth is so high that all substances exist as a dense, solid core. Any object or being at the center of the Earth would be fully compressed into the dense core and wouldn't feel any crushing force.
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 is cochineal what is it used for and where would you obtain it from?
Cochineal is E120 - Red Food Colouring and is made of crushed Cochineal insects.
Would gabbro or obsidian make a better arrowhead?
Obsidian
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.
Why is it difficult to dtermine the absolute age of a sedimentary rock?
In most cases, all we have to date are the clasts in the sedimentary rock. Dating the clasts, however, would yield the age of the source rock from which they were derived rather than the current sedimentary rock.
Which is older a gabbro dike or a gray shale?

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.
Is she have crushed on you?
Hell no!! Who would like you?
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 happened in the Tudor punishment of being crushed?
because they could of committed treason or petty treason.

Why would basalt and gabbro generally have higher chemical weathering rates than rhyolite and granite?
Basalt and gabbro have higher chemical weathering rates than rhyolite and granite because they contain more ferromagnesian minerals like olivine and pyroxene that are more susceptible to chemical weathering compared to the quartz-rich minerals in rhyolite and granite. This makes basalt and gabbro more prone to breakdown and alteration when exposed to weathering agents like water and acids.
Which rock obsidian or gabbro would make a better arrowhead?
Obsidian. It has very fine grain or is amorphous, and it has a conchoid fracture, so it can be worked to a sharp edge and point. Gabbro, on the other hand, has a very coarse grain and it difficult to get and edge or point on at all.
