Volcanic Minerals Oregon State University

Gold in Epithermal Deposits . Epithermal refers to mineral deposits that form in association with hot waters. The deposits form within 1 km of the surface and water temperatures are about 50-200 degrees C. Shallow bodies of magma supply heat. The rising hot water carries dissolved gold and other elements.

2. Gold-laden water heated by magma-molten rock-in Earth's shallow crust forms a variety of lode gold deposits. Hydrothermal-hot water-fluids rich in sulfur form gold ores in rocks of active volcanoes. The deposits of Summitville, Colorado, are an example. 3. Gold minerals form in hot rocks in and around volcanoes.

Ore resources on Mars Wikipedia

Ore minerals, including the incompatible elements, remain dissolved in the hot solution, then crystallize out when the solution cools. Deposits created by means of these hot solutions are called hydrothermal deposits. Some of the world's most significant deposits of gold, silver, lead, mercury, zinc, and tungsten started out this way.

Mineral Deposit Types, Mineralogy, Alteration, Host Rock

Some mineral species melt more easily than others. These are called ore minerals.Ore minerals are formed after some special geological processes. Because they tend to condense in small rock masses, these are called mineral deposits. The mineral deposit is not only related to ore minerals. They always have valuable minerals with them.

Geology of Gold Mineralization & How Gold Deposits are Formed

Gold is relatively scarce in the earth, but it occurs in many different kinds of rocks and in many different geological environments. Though scarce, gold is concentrated by geologic processes to form commercial deposits of two principal types: lode (primary) deposits and placer (secondary) deposits.
