What is the most unique rock, either igneous, sedimentary, or metamorphic, that you guys can think of?

Question

I have this Earth/Space Science question:
"...and which type of rock would you like to be and why?"
It is a rather simple project, just pick a rock and say why you like it. But, I am weird, and I have to be different. I want to find one that is so weird and unique that people are like, "What the hell??" But thats only part of the thing, I need a good reason why I chose this rock, and that seems to be the hardest part. I went to Wikipedia's "List of rocks", which had about ten really awesome unique rocks, but no reason to say why I would want to be that rock. The rocks that I found interesting by name were: Coquina, Greywacke, Harzburgite, Ijolite, Lherzolite, Oolite, Rhomb porphyry, Trondhjemite, Wackestone, and Wehrlite. All are great candidates for the most unique and cool rock, but have little reason to be chosen because they have little to no importance, or general coolness that I can find. Can you find a good reason to choose any of these rocks, or any other rock worth choosing?

Answer 1

Well let me see.

There is a rock in Cape Breton that is possibly the oldest unaltered rock on the planet. It would be cool to have been around in the same unchanged form for billions of years watching the ecosystem of this planet unfold. If I were a patient person.

Or it might be fun to be muscovite and pop like popcorn when heated. If I was a Jungian Yellow.

Or to be a meteorite. If I was a person that loved to travel ;-)

It would be interesting and creative to be a metamorphic rock and mold, create and form something new over and over. If I were an artist person.

Pick a rock that matches your own personality and you will find more things to say about it. Or pick many rocks that you feel describe many of the individual attributes of your own personality and just say it's hard to pick one.

Answer 2

this is purely like one identifies cats, canines and bears etc. or like a project confronted by employing a guy or woman vacationing yet another u . s . a . and seing culmination that he has under no circumstances viewed in his very own u . s . a .. To be short, those 3 forms of rocks have a set of characteristic seen properties and mode of incidence which helped in figuring out them into sedimentary, igneous and metamorphic communities. in specific cases this is not that straightforward to realize this extremely in cases of transitional or blended rocks. The tests are required basically as quickly as we'd want to categorise the rock extra interior the group or want to learn extra for its genesis info and financial significance etc. thnks

Answer 3

I am sure you could make a case for any one of the three types you listed, but I will give you an igneous one. At the northern part of Big Bend National Park there is an "Olivine (fayellite) Granite". Granites normally have quartz, two feldspars and some mafic minerals, such as biotite or amphibole. To have olivine in a granite is very unusual since olivine normally forms at the high end of Bowen's Reaction Series and granite forms at the low end of the series.

Answer 4

Be ooooolitic limestone, if for the name alone! If you are oolitic limestone, you are cool because you are sedimentary, you formed in I believe Wilson facies 5 or 6 by rolling back and forth on a shallow shelf in a warm tropical sea, and every geologist just loves to say your name. You are the highlight of stratigraphy classes, and the best thing to find in the field.

oooo-litic, I say!

Answer 5

Well, I have read that painite is the rarest mineral rock on earth, found only in a very small area.

Answer 6

petrified dinasaur dung

Answer 7

big fan of obsidian myself.
