at subduction zones
Gold is valuable BECAUSE it is rare and it is useful. it doesn't corrode like iron (via rust), it conducts both heat and electricity well and is ductile (soft and workable.)
if you mean gold colours in water colour paintings ; white , yellow , orange and light brown in varying amounts. but for pure colours of gold in oil paintings; gold paint is simply gold fuild substance.
Fool's gold is iron pyrites, iron sulphide, FeS2. It is a sulphide mineral.
It can be identified in the field by the sulfur smell of the powdered mineral. Its metallic luster and pale-to-normal, brass-yellow hue have earned it the nickname fool's gold due to many miners mistaking it for the real thing, though small quantities of actual gold are sometimes found in pyrite. In fact, such auriferous pyrite is a valuable ore of gold.
Pyrite also known as "fool's gold" is a mineral that has both a different chemical, morphological and physical characteristics than gold. Gold is denser (i.e. the same size of gold is much heavier than the that of pyrite). Gold's average density is 17.64 g/cm3 while Pyrite's density is on average 5.01 g/cm3. The chemical formulas are different. Gold's chemical formula is "Au" while Pyrite's is and iron sulfate mineral with a formula of "FeS2". The color is also different, gold appears the color of gold while pyrite is more bronze in color. The crystallographic form of the minerals also vary. Gold is a very soft mineral while Pyrite is much harder (gold has a hardness of 2.5 while Pyrite is 6.5). To distinguish between a sample of each, you could scratch the surface of gold using your fingernail which you would not be able to do with pyrite. You can try to scratch it because pyrite or fools gold much harder then gold so if it doesn't scratch that much it is most likely pyrite or fools gold. You can tell them apart by looking at their reflection and streak. Also, gold is much more dense than pyrite, so the same volume would 'weigh' about 3.5 times more. Gold has a hardness of about 2.5, while pyrite is about 6 (Gold is softer and more malable). Streak is used to distinguish between Gold and Pyrite.
Valuable mineral deposits, like gold, can form in the Earth's crust in areas where there are geological processes that concentrate the minerals, such as in fault zones, near volcanic activity, or in areas where there has been the movement of fluids carrying the minerals.
Ore deposits are mineral deposits that contain valuable metals and nonmetals. These deposits are economically viable for extraction and processing due to their concentration of valuable minerals. Examples include gold, silver, copper, and iron ore deposits.
Gold is a valuable mineral
In the context of mineral deposits, "rich" means that the area or deposit contains a high concentration or abundance of valuable minerals such as gold, silver, copper, or other economically significant minerals. It indicates that the location has a high potential for mining or extracting valuable resources.
little bit of gold,fertile soil,plentiful waters,mineral deposits.
yes jade is an less valuable mineral than gold
gold
Their is some gold, mineral deposits,and natrule gas
GOLD
Igneous intrusions are often associated with valuable mineral deposits such as gold, copper, and nickel due to the process of fractional crystallization where minerals concentrate as magma cools and solidifies. These valuable minerals may be trapped within the intrusive bodies or found in surrounding rocks affected by the intrusion.
no
because china had no deposits of that mineral
