Do you know what this rock is called?

My brain? just kidding,\nphenakite?\ncalcite?\nquartz?\nnumber one choice= aragonite!\ndolomite\ngypsum\nor maybe a combination of calcite and dolomite\n\nWhy the curiosity? Precious gem!\n(congrats on the 2000 points)

I watched that in a documentary! On the History channel or something... sorry I can't actually answer you're question I'm just letting you know that I like what you asked.  Maybe thought, maybe because of all the trade going on? Like people were selling the blue rocks (was it the blue ones? don't remember) they were selling them as jewellery. Actually! I have the answer! The blue rocks are in an ancient story that a blue rock would lead you closer to God - blue mountains - so when trades people came from wales to sell this little blue rock as a pendant they thought "ah ha" and went to mine it to bring it back (by boats) to their village to bring them greater luck!\nMan I'm a genius!

it's a coarse grained light colored igneous rock

dairydahm is right!  It's conglomerate.  Sedimentary (so you were right, too) rocks can contain pebbles of similar or varying sizes, depending where it formed.  Below are some sites that have pics of conglomerates for you to check--if you don't believe us.  (I'm a geology teacher, by the way.  (-; )

It is called a large chunk of ice afloat in the ocean:)\n\nP.S or an iceberg

Can you give us any information?  Where did you see the name?

rocks are made up of minerals

you can spend years here....zorathustrn granite,mica schists..various volcanics  in  canyons bottem  are  evidence trhat  an old mountain range...some say  as  high as  todays  rockies...[by base measurments]  was  eroded away  by  ice flows.....oceans came  and  left.....on  ariving  plant and  animal life  contribute  fossil remains and  calcite[the  making of limestone]mud stones and shales....the  various  banding  give us  ideas to the duration  andlife  of the times.....basically  the  areas  above the  river  are  sandstones  shales  and  mudstone....but there is  marble and dolomites....explore....thers  gotta  b   pics  on  net  somewhere

no a diamond is a type of rock.\n\na crystal is a type of glass.\n\nsimilar, but not quite the same.

A rolling stone gathers no moss - should be 'bryophitic', I think.\n\n"Nomadic fragments of igneous and metamorphic strata, having non-zero quantities of angular momentum, accumulate no forms of bryophitic plant life"

The most difficult part of assessing these sorts of things is that if you haven't been there and seen it yourself, you really don't know what is being observed. As long as there are no facts to confuse the issue, the imagination is free to run wild. \n\nI've read about the Bimini Road before, and find it very plausible that it could be a natural deposit of broken up beach rock. In that depostional environment it is common for the seabed to form hardened layers that can be broken up by a storm and might resemble large flagstones.  As a geologist, it seems to me that the most obvious way to prove that Chinese sailors dumped these rocks is to sample the rocks and determine if they are allocthonous- that is from somewhere else (like China??). Since no one seems willing to present this sort of evidence, the claims don't seem to be scientifically supported.\n\nThe Yonaguni Island  is actually more interesting to me, although I see a dangerous assumption being made by anyone saying these are ten thousand years old. The website is very vague about the water depth, but it appears these may be in only 20 feet of water. That would make it possible for these to be man-made and only be a few thousand or even a few hundred years old. The area of this island is quite active tectonically, and subsidence could have only been within the the last millenium. Dr. Schoch also reports that all of the seemingly shaped rocks are part of bedrock, that is there are no large blocks of stone that would help prove these are manmade. He also reports similar styles of weathering of the local rock on some beaches on the island, so the whole thing could still be naturally formed. Again, there are geologic methods that could probably be used to prove how long these rocks have been submerged, and the fact that no one seems to be trying to prove anything here makes me suspicious that there is nothing to prove; that it is much more profitable to keep generating controversy that makes for good tourism and dive attractions. \n\nTo see how the rock could be tested to determine when it was submerged this could be employed:\n(I quote)\n\n "Burial dating:\nIf a quartz-bearing material accumulates 26Al and 10Be while exposed at the surface and is subsequently buried deep enough that it is completely shielded from cosmic rays (e.g. by deposition in a cave, sedimentary deposit, or deep water body), then the 26Al/10Be ratio will diminish over time, recording the time since burial, according to (Granger and Muzikar, 2001) "\nfrom\nhttp://web.ges.gla.ac.uk/~dfabel/CN_explain.html\n\nSo as a geologist, I remain a skeptic because the parties who have made these discoveries are not attempting to prove scientifically that the evidence is real, for whatever reason.

The answer is Olivine.

It is called a meander or an oxbow.  Wikipedia has a good explanation.

whitish/grayish. It's really just made up of rock. Then again its just a humongous rock that's in orbit with us.

YES BUT CANNOT REMEMBER THE NAME. TRY DOING A SEARCH I KNOW IT IS OUT THERE,
