Ore Deposit an overview ScienceDirect Topics

Magmatic ore deposits may be defined as rocks of igneous origin (see IGNEOUS PROCESSES), which can profitably be mined for their constituent chemical elements.For example, the worth of annual global production from magmatic ore deposits exceeded $10 billion in 2001, and dominates or contributes significantly to world supplies of elements representing more than a third of the periodic table.

TSHA Iron Ore Deposits

The World War II demand for iron and steel stimulated production; small amounts of ore were mined until 1943, when more modern plants were constructed and production revived. According to the United States Bureau of Mines, in 1947 Texas processed 289,273 long tons of ore, and by 1950 Texas ores were being utilized in larger quantities.

Botanical prospecting for uranium Wikipedia

During the early efforts to locate uranium deposits in the United States, the U.S. Geological Survey conducted studies of prospecting through botanical surveys. These studies examined three methods. Each method begins with the identification of an area of interest. This area is then gridded off, which allows the prospector to map samples to specific locations on the ground. The first method, not widely used in the Colorado Plateau, looks for physiologic and morphologic chang

Mineral Resources

Hydrothermal Ore Deposits Concentration by hot aqueous (water-rich) fluids flowing through fractures and pore spaces in rocks. Hydrothermal deposits are produced when groundwater circulates to depth and heats up either by coming near a hot igneous body at depth or by circulating to great depth along the geothermal gradient.

Hydrothermal circulation Wikipedia

Hydrothermal circulation, in particular in the deep crust, is a primary cause of mineral deposit formation and a cornerstone of most theories on ore genesis. Hydrothermal ore deposits. During the early 1900s, various geologists worked to classify hydrothermal ore deposits that they assumed formed from upward-flowing aqueous solutions.

Rock and Mineral Resources Geology

Ore deposits rarely fit snugly into the boxes in which geologists wish to place them. Many may be formed by one or more of the basic genesis processes above, creating ambiguous classifications and much argument and conjecture. Often ore deposits are classified after examples of their type, for instance Broken Hill type lead-zinc-silver deposits
