Is arsenic found in marble?

The chemical formula is CaCO3 (calcium carbonate). \n\nThey probably wouldn't make toothpaste out of it if it had dangerous amounts of arsenic in it. However, the content does vary, since limestone forms in the ocean it will have concentrations of many elements that are found in seawater.  For example in some Florida limestone the concentration of arsenic is 3mg/kg (3 ppm).\n\nMarble is a metamophosed limestone (not a conglomerate). Often in construction trades, polished limestone is called marble, although to a geologist it is still not marble. \n\nIn some water treatment plants  limestone (thus marble) is used to REMOVE arsenic from water. \nhttp://water.usgs.gov/wrri/02grants/2002SD1B.html\n\nI would say if you don't have to put it in your aquarium don't do it. The far bigger problem than the arsenic might be that if your aquarium is slightly acidic it will begin to dissolve the marble, and make the water rather hard. I can't imagine this would be good for most freshwater fish.

You can extract it from Phosphate rock.\n\nLarge deposits are located in China, Russia, Morocco, Florida, Idaho, Tennessee, Utah, and elsewhere.

"Soda ash" is a common name for sodium carbonate, Na2CO3.  This chemical is very soluble in water.  Limestone is calcium carbonate, CaCO3, which is insoluble.  If you tried to use soda ash as an abrasive in a cleanser, it would simply dissolve as soon as it got wet.

It's not that they only occur in concentrations such as veins, but that they can only be mined when they happen to be concentrated.  Metallic elements can also be found widely distributed through the rocks of the earth.  However, elements like gold make up such a small part of the earth's composition that when they are not concentrated, you would need to process so much rock to get a tiny amount of the metal that the cost of mining and processing would exceed the value of the ore.  In that case, there's no reason to try to mine it, since miners are in business to make money.  For gold, the concentration needs to be a few ounces gold per ton of ore to be economical - that's still not much gold, but it's a lot more than is present on average.  For every metal, the break-even point is different.\n\nNow, about how they end up in veins.  The uncommon elements in the earth can only make their own minerals when they get concentrated.  In the bulk of the earth, these uncommon elements get taken up into common minerals by substituting a few of their atoms for a few atoms of the more \ncommon elements in that mineral's structure.  For example, rubidium or strontium may substitute for calcium in plagioclase feldspars and in calcite and uranium may substitute for zirconium in zircon.  Many economically valuable elements like gold and silver are examples of "incompatible" elements, that is, they do not easily fit into common types of minerals.  They go in because they have to, but they wait until the last possible opportunity and they also take the first possible opportunity to \nleave.  \n\nTo use gold as an example, a granite intrusion that is cooling a \ncrystallizing may contain a tiny amount of gold.  All through the cooling melt, elements are coming together to make crystals, but none of the gold is, yet.  As the amount of liquid decreases, the relative amount of the gold in it goes up, so this is the first step in concentration.  The final bits of the granite to crystallize will be enriched in gold.  When the granite is finally solid, but still hot, ground water and water that used to be dissolved in the magma  will be circulating through cracks in the granite.  When that hot water encounters minerals containing the gold, the \nincompatibility of the gold will lead those minerals to break down more easily than their neighbors and release the gold into solution.  As the water moves away from the granite, it is now carrying the gold, which is even more concentrated than it was before.  The water begins to cool off and as it does minerals begin to precipitate. Again, gold will remain in the solution as long as possible, so it is often one of the last things to crystallize.  By then, it may be concentrated enough that it will grow its own crystals of pure gold (small cubes, octahedrons, and wire-like shapes) rather than trying to fit into other crystal structures.  These minerals are left behind in the cracks that the water was moving through, forming veins.  It is those veins that the miners then follow as they mine their ore (rocks containing the concentrated gold, silver, or other metals).

For the first case A marble on a (perfectly) flat surface, will remain in that state until energy of some kind is added.\n\nFor the second case to be as close to perfect conditions you would need to have a moving object out in deep space away from other bodies, because gravity will always be an effect, and in space to avoid the friction of the air.\n\nBut in simple terms the same marble on the flat surface give a push will move until external forces stop it, friction from the air and from contact with the surface.

Here's what I found about marbles in West Virginia.  There are 4 large marble plants still active in West Virginia.  They are:\n\n* JABO-Vitro of Reno, OH (plant in Parkersburg, WV)\n* Marble King of Paden City, WV\n* Champion Agate of Pennsboro, WV\n* MidAtlantic Glass of Ellenboro, WV\n\nThe only numbers I could find are from Marble King's website: "Marble King, Incorporated, located in Paden City, West Virginia, currently manufacturers over a million marbles each day. They operate seven days a week, three hundred sixty-five days a year."  So that means that WV produces at least 365 million marbles per year.\n\nBut apparently, "The largest maker of machine made marbles in the world is Vacor de Mexico, which has an office in Kansas City MO. It is said to produce over 90% of the world's marbles."  And there are only five companies in America that still make marbles.\n\nI am from Fairmont, WV, and my grandfather worked for a glass company in Clarksburg, WV, until he retired.\n\nAbout your other question: I know of at least one town in WV that touches two other states.  The town is called Kenova, WV, and it's called that because it is on the border between KENtucky (Ken-), Ohio (-o-), and West VirginiA (-va).

next to arsenic in what way?\nThey have completely different chemical make-up.

Not sure... sometimes lost items are right in front of our noses....\n\nBut if you happen to find your marbles, please let me know so i can go there and look for some money that i just cant figure out where it went!!    :P

Arsenic (III) oxide and water are the correct reactants.  They will form Arsenious acid (H3AsO3):\n\nAs2O3 + 3 H2O --> 2 H3AsO3\n\nThe proof of acidity is:\n\nH3AsO3  -->  H+  +  (H2AsO3)-\n\nThis shows the possibility of donating a proton.

well its all part of the process of making glass. When blowing glass it is heated to the point of flexibility........almost into a liquid form. The colors and swirls are formed during this state. Marbles are rolled to be solid, thus why the different "demensions" can be seen inside the marble. At times you can see an air bubble. Whites and colors come from the different colors added during the heating process. Just as they make glass beads. Go to Venice, Italy! Its amazing to watch. :)

1. yes they occur in the cracks of rocks but not just metals .. for example quartz is not a metal but it can form veins .. Veins are mineral deposits which form when a fracture or fissure within a larger body of rock is filled with new crystalline material. Veins are believed to form when aqueous solutions migrate through fissures in rock and deposit minerals onto the fissure walls. \n\n2. Ilmenite is a crystalline iron titanium oxide (FeTiO3).\nwhile rutile is a mineral composed dominantly of titanium dioxide, TiO2 so its not an iron ore !!

onyx is a type of quartz ( main constituent silicon)\nalabaster is a form of gypsum (main constituent sulphate)\nmarble is a  form of chalk or limestone ( main constituent  calcium carbonate)\n\nto determine which is which if you have 3 samples, identify alabaster first, alabaster is the softest, either of the others will scratch it.  Between marble and onyx, marble can be identified by dropping a few drops of weak hydrochloric acid on to it, the acid will 'fizz' on the marble as the calcium carbonate reacts with the acid to produce hydrogen gas ( if you dont happen to have any weak hydrochloric acid lying about, use a drop or 2 of kitchen descaler, it is weak hydrochloric acid, and works on exactly the same principle)

Granite hornblende is a source of silicon.\nAs a start, have a look here:

"It is found in a number of minerals including allanite (also known as orthite), monazite, bastnasite, certie, and samarskite. Monazite and bastnasite are presently the two more important sources of cerium. Large deposits of monazite found on the beaches of Travancore, India, in river sands in Brazil, and deposits of allanite in the western United States, and bastnasite in Southern California will supply cerium, thorium, and the other rare-earth metals for many years to come.

The red color is found in many soils around the world.\nThe cause of that is the presence of oxides and hydroxides of Fe and Al.\nThose soils are known as ''weatherized'', usually done by many, many years of exposure to heat and humidity.

Maybe because you put arsenic in the cookies!
