All About Garnets. February 2013 by Chris. rock types and survived alluvial transport downstream frequently occurs as rounded grains in stream and ocean beach sands. It concentrates with heavy minerals because most garnet is about 3.5 times as heavy as water. Garnets, when found in crystals, are easily distinguished from other similarGarnets are most commonly found with reddish shades, but can be, orange, yellow, green, purple, brown, blue, black, pink, and colourless. Blue garnets are very rare. Sometimes the crystals have Garnet Geoscience Australia

Garnet Common Minerals
These garnet sands can be concentrated by wave and current action into ‘heavy’ mineral sand deposits. In most metamorphic rocks, garnets are typically associated with the mica minerals and other metamorphic minerals such as staurolite, kyanite, and sillimanite. Calcium-rich garnet varieties usually form in metamorphosed carbonate rocksGarnet sand reveals rock recycling processes in the youngest exhumed high- and ultrahigh-pressure terrane on Earth. Two garnets in the >200-µm fraction were sourced by UHP protoliths as indicated by a 4.0 × 3.0-µm polyphase SiO 2 inclusion, consisting of quartz and coesite (Fig. 4A), and a 6.5 × 5.5-µm monomineralic coesite Garnet sand reveals rock recycling processes in the youngest

The almandine- and pyrope-rich garnets are most likely derived from the extensive Fennoscandian Shield, while the spessartine-rich specimens are thought to originate from the mid-German VariscanThe garnets found around North River, the Barton Mine location in particular, are not prone to extraction of more than millimeter size pieces. The garnets themselves are sometimes softball size, locked in matrix, but are completely shattered. Better to keep it as Juan said.

The black sand magnetite is a raw material to produce iron and steel. High content magnetite in the top meter beach sands of the north-west of El-Burullus Lake of Egypt is separated and mineralogically and geochemically investigated. Magnetite content obtained by laboratory techniques varies between 2.92 and 0.11 wt%, with 1.15 wt% The Middle Jurassic (Upper Bathonian/Lower Callovian) sands and sandstones of the Cracow-Wieluń Upland contain detrital garnets with high contents of the pyrope molecule (30-73 mol %).(PDF) High (ultrahigh) pressure metamorphic terrane
