Meteorite Identification: Have you found a space rock?
Iron is heavy and most meteorites feel much heavier in the hand than an ordinary earth rock should A softballsized iron meteorite will likely weigh five or six pounds, making it seem unnaturally dense Imagine holding a steel ball bearing as big as a grapefruit Quartz and calcite are the two most common crystals seen while out hunting rocks Meteorites do not have shiny crystal surfaces like terrestrial rocks Some meteorites do have crystals but the presence of a lot of iron will make them obvious meteorites Meteorites do not have layers of minerals in themMeteorite Identification The Meteorite Exchange, IncUses: Basalt is crushed and used as crushed stone, concrete aggregate and railroad ballast Basalt fibres are used in the production of high quality textile fibres, floor tiles, basalt plastic reinforcement bars, basalt fibre roofing felt and glass wool (fibre glass)Rock Identification Guide Mining Matters Crystals of this titaniumoxide mineral are sprinkled in many igneous and metamorphic rocks, but they're sizeable only in pegmatites Ilmenite is weakly magnetic and produces a black or brownish streak Its color can range from dark brown to red Characteristics: Submetallic luster; hardness of How to Identify Black Minerals ThoughtCo Meteorites are solid pieces of rock that are usually densely packed with metal If the rock you’ve found looks like a meteorite, compare it to other rocks to ensure it’s relatively heavy, then calculate its density to determine if How to Tell if the Rock You Found Might Be a Meteorite: 11

Answer Save 6 Answers Relevance tuff luv Lv 4 1 decade ago Favorite Answer It could be magnetite or hematite, but it's hard to say which without actually seeing it hematite is usually blueish with a red tinge, but I've seen some that's blue and very "glittery" Magnetite is usually all black, and I Found a rock Really heavy, magnetic and has silver from steel mills and smelters, the remnant waste product from metal extraction from ores is a heavy and dense product called slag A product that the railroad commonly uses as ballast to anchor rails and ties is such a way as to minimize side movement of such, also allowing for a consistent roadbed and grade throughout the rail system 1 0 AndrewG Lv 7 1 decade ago Almost impossible to What is this silver metallic rock i found?

Identifying NonPrecious Metals : a quick look Looking
Non magnetic metals include aluminium, copper, lead, tin, titanium and zinc, and alloys such as brass and bronze Precious metals such as gold and silver are not magnetic Platinum is not magnetic, but, depending on what other metals is aligned with, can be magnetic in jewelry Mohs scale of hardness The mohs scale of hardness is helpful in identifying metals, and this is a simple test to do It is 3 inches by 3 inches, nonmagnetic and relatively heavy (17 lbs) Are those regmaglypts on the surface? What type of rock is this? Thoughts???Ok I'm hooked! I'd like to know what kind it is, too! :confused: :) Kevinito 2013Jun26, 05:11 PM Ok I'm hooked!

[Archive Nearly all of Earth's major iron ore deposits are in rocks that formed over 18 billion years ago At that time Earth's oceans contained abundant dissolved iron and almost no dissolved oxygen The iron ore deposits began forming when the first organisms capable of photosynthesis began releasing oxygen into the waters This oxygen immediately combined with the abundant dissolved iron to produce Iron Ore: Sedimentary Rock Pictures, Definition MoreGold is a very rare and precious metal that is soft, malleable and heavy, and it is often found with other minerals, such as quartz Learn about the differenIdentifying Rocks : Identifying Gold Rocks YouTubeGrains: Grains that are not crystals in rock do not have flat shiny faces They are rounded, like grain of sand, or jagged, like a piece of broken rock Grain Size: Grain size in rocks can mean the size of crystal grains or of fragments: Coarse Grained: most of the rock is made of grains as large as rice, or larger Medium Grained: the individual grains can be seen without a magnifier, but Rock Key Mineralogical Society of America
What Kinds of Metals Do Not Stick to Magnets? Sciencing
These metals are made up of billions of individual atoms that have magnetic properties, meaning magnets stick to them firmly Some examples are iron, cobalt, nickel, steel (because it is mostly iron), manganese, gadolinium and lodestone Some metals, such as iron, are referred to as magnetically soft because they become strong temporary magnets when you hold a magnet near them but lose some or Is the black shiny? Can you scratch it Is it magnetic? Three questions to ponder It could be a meteorite if the black is from burning on the ride through the atmosphere But they are rare If it is heavy it might be a metallic ore answered Aug 1, 2014 by Weasel (58,980 points) No it is not shining It can not be scratched by quartz I did not test for magnetic commented Aug 5, 2014 by a very hard and heavy stone Question heavy black rock non magnetic, heavy black rocks, heavy brown non metalic stone, i found a black rock very heavy looks like it has gold fleaks on it what kind rock could it be, silver rock non magnetic, super heavy hard silver rock not magnetic, very heavy black rock, very heavy magnetic rocks , what black rock is super heavy Click on a term to search for related topics Very Heavy Rock (reposted) TreasureNet HEAVY: Most meteorites contain a significant amount of FeNi metal, and are thus heavier (highdensity) than rocks typically found at the surface of the Earth There are exceptions to this rule Some meteorites contain no metal at all, and are about as heavy as the dark volcanic rocks found in Hawaii and the Columbia Gorgemeteorite identificationMagnetic: yes Conductive: no Cleavage: none Relative Density: 51 Distinguishing Characteristic: Magnetic Origin of your Samples: Madoc, Ontario Other Occurrence: South Africa, Germany, Russia and USA Uses: Magnetite is the primary ore of iron Iron is used to make steel used in buildings, bridges, vehicles and ships – just to name a few Mineral Identification Guide Mining Matters
