It is a cubic mineral with the spinel type of structure. Magnetite is an iron oxide, which is so named for its strong magnetic property. Gold-bearing quartz id often of the milky variety. Gold occurs in many types of rocks but is common in small amounts in hydrothermal veins associated with quartz. Gold is cubic and has been found in well-formed octahedral and dodecahedral crystals, although it usually occurs as dendritic growth and occasionally as rounded masses (nuggets). Its malleability, relatively low melting point and chemical inertness have since time began made it ideal for works of art like the mask that covers the upper body of the mummified 14th Century Egyptian King Tutankhamen. Gold is steeped in history and has long been viewed as the most highly prized of metals. The colour is usually dark red inclining to violet-red. It is named after Alabanda, a town in Turkey, where mining, cutting and polishing of the stones was practiced in ancient times. There are 6 members of the garnet group of which Almandine, an iron silicate, is most common to the Territory. Garnet is really the name for a group of minerals, with a common crystal habit and chemical composition. Industrially, garnet is used as an abrasive. Garnet is a typical mineral of metamorphic rock, usually forming isolated crystals disseminated through the rock.
