Locations of Deposits

Deposits are typically found in shales, cherts, limestone, dolomites and sandstone as well as hydrothermal veins or as chemically dissolved phosphate minerals in igneous and metamorphic rocks. One of the world's largest phosphate deposit is the Phosphoria Formation, located in southeast Idaho.

Nov 07, 2007 The geomorphology of China can be divided into several parts. The historical centre of Chinese culture is on the loess plateau, the world's largest Quaternary loess deposit, and on the alluvial lands at the east of it. The alluvial East China plain extends from just south of Beijing in the north, to the Yangtze river delta in the south, punctuated only by the igneous Shandong highlands and

Continental slope limestones of Lower and Middle Triassic

Jun 01, 1998 During the Early and Middle Triassic in South China, tectonism was strong and the patterns of sea-level fluctuation were complicated (Wang et al., 1995; Bao and Feng, 1996), which produced varied sedimentary environments in each age and complex amalgamated beds of the slope limestones.A major influx of siliciclastic deposits marks the termination of carbonate deposition and

Limestone Wikipedia

Limestone is a common type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more

Limestone: The Calcium Carbonate Chemical Sedimentary Rock

Some deposits have chemical grades as high as 95% CaCO 3. However, some areas are completely without any suitable limestone deposits. Most of the cost of limestone to the customer is determined by how far away it comes from and how it is shipped. Shipping by barge on water is cheaper than by train which, in turn, is cheaper than shipping by truck.
