Gold is a dense, soft, unreactive metal with a distinctive yellow color. Gold is a noncorrosive, durable, unreactive metal. However, it will dissolve in aqua regia (a mixture of nitric and hydrochloric acids). Because of this, gold is naturally pure and seldom makes compounds in nature. Nevertheless, gold is commonly alloyed with silver, with minor...
Gold is believed to have formed in the collisions of supernovas and neutron stars. This occurred before the solar system was formed. Gold went to the Earth's core during the planet's formation. It is accessed today thanks to asteroidbombardment. Molten lava and volcanic eruptionshave also brought gold to the surface. Earthquakes play a major role, ...
Gold may occur as deposits called lodes, or veins, in fractured rock. It may also be dispersed within Earth's crust. Most lode deposits form when heated fluids circulate through gold-bearing rocks, picking up gold and concentrating it in new locations in the crust. AMNH. Two significant episodes of geologic activity worldwide resulted in the format...

There are many types of gold deposits, including epithermal vein deposits, intrusion-related breccia pipes, mesothermal turbidite, greenstone-hosted deposits, contact deposits (skarns), replacement deposits, disseminated ores, placers, and Archean banded-ironformation deposits. There are about 11 well-characterized gold deposit types. Arguably more...
The distribution of gold in the US is uneven. Most gold deposits are in Alaska, California, Nevada, Colorado, and Arizona. Most of the main gold-producing districts are in the mountainous areas of the United States, where folding, faulting, and igneous intrusions have deformed the rocks.
The shapefiles with gold deposit types in North America are from U.S. Geological Survey, 2001, National Mineral Resource Assessment 1998: Circular 1178, U.S. Geological Survey, Reston, Virginia.
