· Minerals are elements which are found on the earth and in foods. They are required by our bodies for proper development and functions. These minerals that are essential for our bodies include Calcium, Phosphorus, Potassium, Sodium, Chloride, Magnesium, Molybdenum, and Selenium.
The minerals formed in these evaporite deposits depend on the composition and temperature of the saline waters at the time of deposition. Significant evaporite resources occur in the Great Basin Desert of the United States, mineral deposits made forever famous by the "20mule teams" that once hauled boraxladen wagons from Death Valley to the railroad.
For example, any mineral that is found in nature in its native statethat is, not combined with any other elementis called a native element. While gold and silver are two wellknown native minerals, the only native mineral commonly found in Kansas is sulfur. All other minerals are combinations of elements.
Minerals are found in the cracks, crevices, faults or joints in igneous and metamorphic rocks when the molten magma comes upward through earth's crust.
