Photos of gold ores, quartz, telluride gold ore and gold specimensSometimes the gold is in a finely divided state, sometimes in particles of considerable size, as nuggets, grains, scales, plates, threads and wires in quartz rock. It occurs also in a finely divided state disseminated through schistose rocks, slates and some sedimentary rocks like line. In these cases the rock has been.picture of line with quartz gold ores,California Gold vein formation, Rich gold quartz oreVeins of gold bearing quartz are well known in California - their formation and the gold they contain are of interest.John Frank

These can be small particles of quartz, feldspar, clay minerals, pyrite, siderite, and other minerals. It can also contain large nodules of chert, pyrite, or siderite. The calcium carbonate content of line gives it a property that is often used in rock identification - it effervesces in contact with a cold solution of 5% hydrochloric.

With increasing new data, studies on the geochemistry of gold deposits can be used to trace the origin of ore-forming fluids, the source of gold, and the . Gold deposits related to magmatic fluids at 150–250 °C are generally accompanied by wall-rock alteration, with a mineral assemblage of quartz + K-feldspar + pyrite.
The color of pure Gold is bright golden yellow, but the greater the silver content, the whiter its color is. Much of the gold mined is actually from gold ore rather then actual Gold specimens.

The mineralization, which in the upper parts of the mines has undergone heavy supergene alteration, consists of veins, bedding-plane 'flats' and irregular void infills in dedolomitized Carboniferous Line. Irregular, highly vuggy deposits are characteristic. The Great Orme 'ore' typically shows, when not oxidized,.
As a very common mineral, calcite can be seen in many different rocks including line, dolomite, and marble. Although calcite is commonly white, it can appear in various colors due to chemical impurities. Calcite can be distinguished from other similar looking minerals (such as quartz and feldspar) by its effervescent.
Although hydrothermal mineral deposits may form in any host rock, deposition is preferentially influenced or localized by certain kinds of rock. For example, lead-zinc-silver ores in some parts of Mexico occur in dolomitic rather than pure line; the reverse is true at Santa Eulalia, where massive sulfide deposits end.
Colors and finishes for Silestone quartz surfaces and kitchen and bathroom countertops.
For example, the minerals pyrite and gold are always metallic yellow in color (although they differ in other characteristics such as hardness). Some minerals, for example quartz (see examples pictured below), come in every color of the rainbow and thus, color is not useful for identification of those minerals. Sometimes it is.
