Kimberlite pipes are underground rock columns formed by volcanic eruptions, and they are a leading source of diamonds and other gemstones. Fipke and Blusson's find launched a major diamond rush – one of North America's most intense mineral rushes – and diamond production in Canada exploded.
Rock samples found in Greenland - which were formed at the Earth's formation - contained a marginally higher ratio of the tungsten isotope 182W compared to more modern rock.
Platinum is found in layers of sulphides, which are located in some igneous rocks. South Africa and Russia have the largest reserve of this rare metal.
Platinum is a chemical element with symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal.Its name is derived from the Spanish term platino, meaning "little silver".. Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements.It has six naturally occurring isotopes.
If these rocks form at very shallow depths they may be called hypabyssal or subvolcanic rocks, and we may also see porphyritic textures (e.g. dykes and sills). If they form at considerable depth they are called plutonic rocks and the respective rock bodies may be called stocks, or batholiths, or plutons.
Native platinum is an exotic mineral specimen and an expensive metal. Unfortunately, well formed crystals of platinum are very rare and the common habit of platinum is nuggets and grains. Pure platinum is unknown of in nature as it usually is alloyed with other metals such as iron, copper, gold, nickel, iridium, palladium, rhodium, ruthenium and osmium.
Platinum is available for investment in many different forms including paper platinum and platinum bullion. Physical platinum bullion is most commonly found in coin, round and bar form with several size options for each.
What does platinum look like in raw rock form?? how do. I find out if the rock I have is platinum or what it is?? .It's metallic and I took a file to it it left file marks, under a loop it looks like the metal is weaved it also looks gold it has sparkles
Ore is a solid material from which a metal or mineral can beextracted, while diamond is classified as a mineral formed in … rocks. No process except cutting away excess diamond can change amined diamond, in this case into a gemstone.

Placer deposits of platinum are therefore to be looked for in the vicinity of masses of such peridotite rocks. Historically, before the hard rock supplies came on line, nearly the entire world's supply of platinum came from the Ural Mountains in Russia.
Pegmatite: Pegmatite is an igneous rock composed almost entirely of crystals that are over one centimeter in diameter. The specimen shown here is about two inches (five centimeters) across. The specimen shown here is about two inches (five centimeters) across.
The source of platinum and palladium deposits is ultramafic rocks which have enough sulfur to form a sulfide mineral while the magma is still liquid. This sulfide mineral (usually pentlandite, pyrite, chalcopyrite, or pyrrhotite ) gains platinum by mixing with the bulk of the magma because platinum is chalcophile and is concentrated in sulfides.
Platinum is the rarest and most expensive of the precious metals. High-end rings, bracelets, necklaces, and earrings are fashioned from Platinum. Platinum jewelry is rare and exotic, and is the fastest growing jewelry material in the world.
The Merensky Reef is the rock in Transvaal in South Africa which contains the most of Platinum Group Metals. The rock is situated in Bushveld Igneous Complex. . It was discovered by Mr. Hans Merensky in the year 1924 and hence named after him.
Mar 02, 2010· The following rock sample was discovered recentley in a creek in Southern BC with a metal detector. I am putting it online to try and determine if it is Platinum of some or ore like Silver or ...
Platinum is the rarest and most expensive of the popular precious metals. It is much rarer then Gold. Due to its rarity and value, it is not readily available to mineral collectors and is seldom represented in in all but the highest-end mineral collections.
Platinum is present in the ultrabasic rocks associated with plate boundaries--serpentine, olivine and so forth. Like diamonds, platinum comes from the earth's mantle. When these rocks are weathered out, the durable, heavy platinum comes to rest at the same locations as the gold.
Platinum is rarely found on the Earth's surface and is in fact 30 times rarer than gold. Sources for ore rocks often exist in areas of stream flow in the form of placer deposits.
The gold is formed in a mossy crystalline pattern on the surface of the rock. This very large nugget gold specimen is from Alaska, and shows the signs of wear and tumbling in a river environment.
Crystal faces form only where there is enough open space in the rock mass to allow the natural geometric forms of the crystals to develop as free faces. Granite is composed entirely of intergrown crystals of quartz, feldspar, mica and other minerals.
Iridium (one of the platinum group metals) is one of few metals that have a higher specific gravity than gold, being 22.6. ... with quartz in the form of veins which protrude through the general mountainous rock–referred to as "country rock ...

Platinum is a rare precious metal, sometimes found in this nugget form in nature. It is used in the chemical industry as a catalyst, and in jewellery. This platinum nugget is on display at the Russian State Depository for Precious Metals, in Moscow, Russia.
Dec 24, 2011· Known occurrences of platinum in its native metallic form are restricted to a handful of locations, including the Urals mountains and the Kamchatka Peninsula in Russia, and …
Platinum occurs in dark silicate rocks with minerals that contain iron and magnesium. It is usually found as fine grains or flakes scattered throughout the rock or as thin layers of metal ores called sulfides.
Platinum wasn't formed in or on the Earth. It was produced by nuclear fusion in a supernova explosion. This metal, gold, silicon, osmium and a bunch of other rare metals, were then incorporated into the gas cloud from which the Solar System was formed.
