The Argyle Diamond Mine was a diamond mine located in the East Kimberley region in the remote north of Western Australia.Argyle was at times the largest diamond producer in the world by volume (14 million carats in 2018), although the proportion of gem-quality diamonds was low.It was the only known significant source of pink and red diamonds (producing over 90% of …
Shale is a rock composed mainly of clay-size mineral grains. These tiny grains are usually clay minerals such as illite, kaolinite, and smectite. Shale usually contains other clay-size mineral particles such as quartz, chert, and feldspar. Other constituents might include organic particles, carbonate minerals, iron oxide minerals, sulfide ...

The following outline is provided as an overview of and topical guide to mining: . Mining – extraction of valuable minerals or other geological materials from the earth, usually (but not always) from an ore body, vein or (coal) seam. Any material that cannot be grown from agricultural processes, or created artificially in a laboratory or factory, is usually mined.

Metasomatism (from the Greek μετά metá "change" and σῶμα sôma "body") is the chemical alteration of a rock by hydrothermal and other fluids. It is the replacement of one rock by another of different mineralogical and chemical composition. The minerals which compose the rocks are dissolved and new mineral formations are deposited in their place.
Abstract. Volcanogenic massive sulfide deposits, also known as volcanic-hosted massive sulfide, volcanic-associated massive sulfide, or seafloor massive sulfide deposits, are important sources of copper, zinc, lead, gold, and silver (Cu, Zn, Pb, Au, and Ag).
Fish Hoek (Afrikaans: Vishoek, meaning either Fish Corner or Fish Glen) is a coastal town at the eastern end of the Fish Hoek Valley on the False Bay side of the Cape Peninsula in the Western Cape, South Africa.Previously a separate municipality, Fish Hoek is now part of the City of Cape Town.As a coastal suburb of Cape Town, Fish Hoek is popular as a residence for …
Howlite is also known by the names White Buffalo, Sacred Buffalo, Lapis Howlite, White Turquoise, Silico Boro Calcite, and Kaolinite. Howlite is most notably found in Canada, specifically in Nova Scotia, Newfoundland, and New Brunswick. But it can also be found in the USA, Russia, Germany, Mexico, Namibia, Pakistan, and Turkey.
Volcanic Geodes. The most widely known and sought-after geodes are those that formed in areas of volcanic activity. Voids in basaltic lava flows often are infilled with agate, quartz, opal and other material delivered by hydrothermal water or groundwater. Some voids are spaces occupied by gases that failed to escape the lava flow before its surface crusted over.
Orthoclase as a Feldspar Mineral. Orthoclase is a member of the alkali feldspar series. The alkali feldspars include albite (NaAlSi 3 O 8), anorthoclase ((Na,K)AlSi 3 O 8), sanidine ((K,Na)AlSi 3 O 8), orthoclase (KAlSi 3 O 8), and microcline (KAlSi 3 O 8).. These feldspar minerals form a solid solution series between NaAlSi 3 O 8 and KAlSi 3 O 8.The minerals in that series crystallize …

A gold nugget is usually 70 to 95 percent gold, with the rest being mainly silver. Pure gold is a bright golden yellow, but the higher the silver content, the whiter the hue. Most of the gold extracted comes from gold ore rather than gold specimens. The ore is usually brown, iron-stained rock or massive white Quartz, with only minute traces of ...

Kakiemon (Japanese:, Hepburn: Kakiemon yōshiki) is a style of Japanese porcelain, with overglaze decoration called "enameled" ceramics. It was originally produced at the factories around Arita, in Japan's Hizen province (today, Saga Prefecture) from the Edo period's mid-17th century onwards. The style shares much in common with the …
Hard-paste porcelain contains kaolinite, feldspar and quartz and it's fired at temperatures of up to 2,552 °F. Soft-paste porcelain features a blend of kaolin, quartz, feldspars, and nepheline syenite or different types of feldspathic rock, but since it's fired at lower temperatures it's not as durable or as hard as other types of porcelain.
