Can anyone give me information on a mineral called Feldspar.  My daughter has to do a report on this and she is in 3rd. grade.  I need to know where it is found. what type of rock and what is it used for.  We are suppose to be creative.  I am ready to pull my hair out.  Thanks.

Feldspar is one of the most abundant minerals on the planet being found in many types of rocks. Feldspar is easily broken down by weathering processes.\n\nThe following are a list of reputable sites. Although wikipedia has a lot of informtion it is not listed as a credible site. Anyone can list information there as they can here.

Si is the most abundant mineral element, but feldspar would be the most abundant mineral as far as rocks & minerals. Quartz comes in second.

The mineral graphite is made up entirely of carbon atoms. Graphite is found in your pencil "lead". Many students tend to believe that pencils actually contain real lead. This is not true. They used to use real lead until everyone realized that it makes you sick.\n\nDiamonds are also made up completely of carbon. It was just luckier than graphite. It went under lots of heat & pressure for a very long time. Why is this lucky? Because it turned into a diamond. Diamonds are used for jewelry of course but crushed diamonds are also used on the ends of drill bits. This is because diamonds are the hardest of all minerals. Diamond drill tips can drill through any type of rock.\n\nGood luck with the report!

Porphyry & Basalt are both igneous.\n\nPorphyry is an intrusive igneous rock w/ different crystal sizes.\n\nPorphrytic is a texture term that is often used to describe certain types of igneous rocks having two distinct crystal sizes. The large crystals inside the rock are called phenocrysts. Porphyrtic granite is an example. I tell students that it reminds me of a chocolate chip cookie w/ the large crystals representing the chocolate chips. That usually helps them to get it.\n\nBasalt is an extrusive igneous rock composed mainly of darker minerals such as magnesium.\n\nLimestone is a sedimentary rock as is shale.

1.what is the most heat resisstant materian on earth?\n(clue:used by NASA for ther Stardust Sattelite)\nYet NASA plans to do just that, using a lightweight insulating material called aerogel. Composed of over 95 percent air, aerogel is the lightest man-made material on earth. And although aerogel will be used in the depths of space to conduct research in astrophysics, it has hundreds of down-to-earth applications, as well.\n\n2.Where is Yahoo!'s headquarter?(clue: CA)\nnorth Sunnyvale, CA\nhttp://www.svcn.com/archives/sunnyvalesun/02.16.00/yahoo-0007.html\n\n3.tell me 2 diffrences between Plutonium and Uranium(clue: BOOM!!, Krrrttzzz rrrtzz..)\n\nPlutonium\n\nPlutonium was discovered, secretly, in 1940 by Glenn Seaborg with Wahl and Kennedy at Berkeley and publicly reported in 1946. Plutonium was extracted from uranium ore in 1947. Until recently the major use of plutonium has been for nuclear weaponry, it now finds its best use in deep space probe electricity sources . \nAtomic number-94Densityg/mL19.8\nAtomic weightu244Melting pointK913\nBonding radiusA-Boiling pointK3503\nAtomic radiusA-Heat of vaporizationkJ/mol344\nIonization PotentialV6.06Heat of fusionkJ/mol2.84\nElectronegativity-1.28Specific heatJ/gK0.13\nThe oxide is amphoteric.\nCrystal are monoclinic.\n\nUranium\nUranium oxide has been used since Roman times for yellow pigments in glass.

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!

lithophysae - Commonly known as thundereggs, lithophysae (Latin for "rock bubbles") originate as spheroids drawn from the rhyolite into the immiscible components of co-eruptive rhyolite-perlite lava flows and domes.  Portions of rhyolite are pulled by turbulence or buoyancy from the parent rhyolite into the perlite, forming spheres which, as temperatures drop to a critical point, crystallize, driving dissolved gases out of solution. \n\nex. gas bubbles trying to escape the obsidian lava flow and subsequently supplying the chemical constituents for the minerals lining the bubbles\n\nspherulites - A small, usually spheroidal body consisting of radiating crystals, found in obsidian and other glassy lava rocks\n\nex. feldspar fibers within obsidian with interstitial crystalline silica are common and represent very rapid crystallization prior to the chilling of the surrounding glass

Gaspeite is considered a rare mineral, being found in only a few localities, but it is becoming a popular mineral in the semi-precious stone markets. It is being used as a cabochon in sterling silver jewelry with such notable minerals and material as turquoise, malachite, azurite, onyx and coral. Gaspeite's light green, almost apple green color is quite unique and not hard to mistake. It real accents the banded greens of malachite and the blue green of turquoise. Carved material is generally homogenous, but it may contain portions of its brownish host rock which may give it a distinctive character. \nGaspeite is found as a secondary mineral around nickel sulfide deposits. It was thought of as just a gangue mineral by miners when it was encountered and usually placed in the mines dumps or tailings. A gangue mineral is a mineral that probably contains the ore metal, but its chemistry is such that processing it is either impossible or unprofitable. Such was the case with gaspeite despite being rich in nickel. Of course lapidary craftsmen have a different view of gaspeite's profitability! Gaspeite is named for its type locality of Gaspe' Peninsula, Lemieux Township, Gaspe'-ouest County, Quebec, Canada, but the best material of late is coming from North of Perth, Australia. \n\ncharacteristics-\nColor is a pale green to apple green. \nLuster is vitreous to dull. \nTransparency- Crystals are usually translucent, massive material is opaque. \nCrystal System is trigonal; bar 3 2/m. \nCrystal Habits include rhombohedrons and scalenohedrons, but crystals are very rare. More commonly found massive. \nCleavage is perfect in 3 directions forming rhombohedrons. \nFracture is uneven. \nHardness is 4.5 - 5. \nSpecific Gravity is 3.7 (somewhat heavy for a translucent mineral). \nStreak is yellowish green. \nOther Characteristics: Effervesces slightly in hydrochloric acid.\n\nCARE-\nTo maintain the original condition of your jewelry, polish your pieces regularly using a non-abrasive cleaning cloth.\n  \nSoap and water will also help keep your jewelry looking good. Remember do not dry jewelry off with paper towels or tissues, always use a soft cloth.\n  \nWhen you are not wearing your jewelry, store it in a cool, dry, soft place. \n  \nNever immerse jewelry in chlorine, salt water, mineral springs, and avoid contact with suntan lotion. Remember, some household cleaners contain chlorine bleach. These will cause discoloration and also loosen the gemstones.\n  \nAvoid abrasive cleaners, detergents and commercial jewelry cleaner "dips" especially if the pieces have an oxidized finish.\n  \nNever use an ultrasonic cleaner, ammonia or any chemical solution to clean opaque gemstones, such as turquoise, malachite, onyx, lapis lazuli and opals. They are a porous stone and may absorb chemicals, which build up inside the stone and cause discoloration. Simply wipe them gently with a moist cloth until clean.\n  \nIf your jewelry contains gemstones or pearls, do not immerse in water, as this can loosen some settings. Never use dips or abrasives cleaners on gemstones.

There is a whole battery of scientific tests used in mineral identification today however there are a number of tests that have been in use for a very long time which still work well.\n1) Observation - what does it look like, colour, the streak it leaves on an unglazed tile. the weight in your hand etc.\n2) Hardness. Its resistance to being scratched by a range of other minerals (Moe's scale)\n3) Density - how much it weighs compared to the same volume of water.\n4) The shape and form of its crystals.\n5) Chemical analysis.\nIf you put these together with a lot of experience there are not many minerals you cannot identify.

Wow, the Russians made toy mines? I didn't know that they had a mine special for children. I thought that mines are used to kill everyone- men, women, children etc.

I like "Set In Stone", but it might be too common and not descriptive. What is "set in stone"? The high price? Could have bad connotations of being unbending and not customer friendly.\n\nYou don't give details of the type of stone company. Is it Countertops, building surfaces, memorials, statuary?\n\nConsider an appropriate "A" word to get the phone listing at the top of the page : Always or  Absolute\n\nI agree with the previous post. You want the name to be descriptive and give confidence - not a cutsie name.\n\nDoes your dad offer full services? Computerized wet saws? Polishing of surfaces? If so and he's not a middleman, consider something like "Technologies" for the end of the name.\n\n"Absolute Granite and Marble Technologies"\n\nOr use one of the color names of the granite or marble (but be careful of trademark. (Dakota Mahogany? A trademark?)\n\nSanta Cecelia, Medura Gold, Alabaster, Kashmir, Juperana, . . . \n\nLook at the complete list of names here: http://www.findstone.com/country-stone.htm\n\nOne example of a cool one that is already taken is Blue Pearl Stone Technologies of LaGrange, IL\n\nHope this helps.

A few years ago (1980s) a company was marketing a nuclear device for determining metal content of rocks.  This was a hand held device, and it worked very well.  I don't remember the manufacturer, but I know that it existed, and I saw it work.  The only problem was the nuclear source material.  In order to penetrate to any depth in the rock, it's nuclear source needed to be very powerful.  I think this was considered too much of a liability, and the company quit manufacturing the device.  I'm sure that you can still find one around.  I saw this demonstrated at a geologist's convention in Reno.  I think it was 1983 or 1984.

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 !!

Cool. I hope you found some good ammonites. You may have been in the Cretaceous Western Interior Seaway, which once connected what we now call the Gulf of Mexico to what is now the Arctic Ocean. The Pierre Shale is full of clams, ammonites, and baculites. \n\nThe Western Interior Paleontological Society has some good publications:\nhttp://www.wipsppc.com/#\nHere is link to a Pierre Shale field trip of the WIPS in Colorado:\nhttp://www.paleocurrents.com/baculite_mesa/index.html\n\nHere is an awesome website put together by Dr. Ron Blakey at NAU. For your interests, the first place to start would be paleogeography of the Southwestern US, which has paleogeographic maps of each major period (that include southern Colorado):\nhttp://jan.ucc.nau.edu/rcb7/paleogeogwus.html\nThe top page of his site is at:\nhttp://jan.ucc.nau.edu/rcb7/\n\nYou might also want to buy a copy of "Roadside Geology of Colorado". This series of books is written by geologists who are familiar with the state they write about and describe the geologic features that can be found along the major highways. Here's the cite:\nChronic, H. 1980. Roadside geology of Colorado. Mountain Press Publ. Co., Missoula, Montana, 334 p.\n\nThe Colorado Geological Survey sells a map for $7 that is titled "Colorado Geologic Highway Map" that shows lots of geology information, as well as a lot of other high quality geology related publications:\nhttp://dnr.state.co.us/geostore/ProductInfo.aspx?productid=MI-38\n\nHere is the USGS page for Colorado:\nhttp://www.usgs.gov/state/state.asp?State=CO\n\n\nEnjoy.
