7 Sedimentary Minerals and Sedimentary Rocks

The term siliciclastic refers to sediments composed mostly of silicate minerals. The most common sedimentary rocks including shale, sandstone, and conglomerate form from siliciclastic sediments. Other, less common, kinds of sedimentary rocks consist of carbonates (in limestones), iron oxides and hydroxides (such as hematite or goethite), or other minerals.

GENERAL CHARACTERISTICS OF SEDIMENTARY ROCK

2001-3-16 mainly hosted in sedimentary rocks. The ores typically have low gold concentrations but are present as large tonnage masses, so that large, low-cost open-pit mining methods are used to exploit them. These deposits commonly have 0.5 to 30 million ounces Au per deposit (Cox and Singer, 1992). Carlin-type deposits get their

Sedimentary Rocks, Kentucky Geological Survey, University

Sedimentary Rocks Sedimentary rocks are the most abundant rock type exposed at the surface of the earth and cover about 99 percent of Kentucky. They were formed by the accumulation of rock fragments, shell fragments, plant material, muds, and sands, which were transported to their present locations by water, air, wind, or ice to form clays

Uranium Occurrences in Sedimentary Rocks of

2010-8-7 Uranium occurs in sedimentary rocks at many localities in Pennsyl vania. The rocks range in age from Late Devonian to Triassic. Many of the known occurrences were examined by the author during of test mining at the Mount Pisgah uranium occurrence (Klemic and Baker, 1954) near Jim Thorpe. Several other occurrences have been
