Why vesicular texture is not associated with peridotites?
Peridotites are invasive rocks formed underneath the earth's surface and the high pressure conditions dodge gases from forming and getting away
Is olivine an important mineral in peridotites and other ultramafic rocks?
Yes, olivine is a key mineral in peridotites and other ultramafic rocks, typically making up a substantial portion of their composition. It is a primary mineral in these rocks, alongside other minerals like pyroxenes and chromite. Olivine's presence helps characterize these rocks and plays a role in their formation and geologic processes.
What are the deepest fossils ever found and where were they discovered?
The deepest fossils ever found are microbial fossils discovered in rocks from the ocean floor, known as serpentinized peridotites, in the Samail Ophiolite in Oman.
Is streak the color of powder?
Streak refers to the color of a mineral in powder form.
What is the flame color of the element Mercury?
the color of mercury is gray it has no color
Why vesicular texture is associated with peridotites?

Where is peridotite found?
Peridotite is a dense, coarse-grained plutonic rock that contains a large amount of olivine. Spinel-bearing peridotites and plagioclase-bearing peridotites are foliated.

Why vesicular texture is not associated with peridoties?
Vesicular texture is characterized by the presence of numerous gas bubbles, which typically form during rapid cooling and solidification of lava that is rich in volatiles. Peridotites, however, are ultramafic igneous rocks primarily composed of olivine and pyroxene, and they form at greater depths in the Earth's mantle under high pressure and temperature conditions where gas escape is minimal. This depth prevents the formation of vesicles, making vesicular texture incompatible with peridotites. Instead, peridotites generally exhibit a coarse-grained, granular texture typical of slow crystallization in a high-pressure environment.
What rocks are the most common?
Probably granites and basalts, although there is a tremendous variety of igneous rocks in the earth's crust including peridotites, granulites and gabros.

Why vesicular texture not associated with periodites?
Vesicular texture is characterized by the presence of gas bubbles trapped in solidified lava, typically forming in volcanic environments where rapid cooling occurs. Peridotites, on the other hand, are coarse-grained igneous rocks primarily composed of olivine and pyroxene that form in the Earth's mantle under high pressure and temperature, where gas escape is limited. As a result, the formation processes of peridotites do not allow for the development of vesicles, making vesicular texture incompatible with their formation conditions.

What kind of lava forms a peridotite rock?
None. Ultramafic peridotite is not a volcanic rock (is intrusive). Basalt rock (yes, volcanic) is the efusive equivalent of peridotites. Do you know that beneath peridotite, a rock named kimberlite is found and this is the main source of diamonds, being widely beneficiated in south africa? Good luck with your ultramafic and may be you can find some diamonds too !!
What is the job market for acting?
yes acting is hard, if we are talking about the good acting (well yes its hard), but if we are talking about the sloopy acting of course its easy. for acting you have to have a lot of concentration and you have to know a lot of basic things that most of the people that take classes of acting and that they are professional actors do bnot know. some of you people wont know what blocking a scene is, or maybe you guys dont know that you have to mantaing a balance on scene, also you have to know about diction and other stuff to, acting is not all about you learn your lines you do your part good and evreybody gives you a round of applusse. no an actor is much more thatn that. i know cause i am an actor and most of the people that i know that call themselves actor do not know some of thoose basic stuff.
What is the color of absence of color?
The color of absence of color is white.
