Orris, G. Paradis 1G. Lefebure of the B. Simandl, D. Recently, the Chengkou and Ziyang witherite deposits have been discovered in China Wang and Chu, Witherite deposits may form due to severe depletion of seawater in SO -2 4 and enrichment in Ba Maynard and Okita, Reimer, T. Alternatively, these deposits could have formed by high temperature replacement of barite by witherite Turner and Goodfellow, These deposits form the world's second most important source of copper, and are found in chemically reduced zones, commonly associated with evaporite and red oxidized sandstones, in continental marginal, lacustrine, or continental settings.

These interfaces are included in the folder GlobalDBSystem The program Documenter allows users to examine each table and field of each category of table Data, Junction, Lookup, and Service depending on their roleswhich complements the more general web page style documentation.

    Geological SurveyOpen-File Reportpages Because most of the original records were compiled before when locations were read from small scale paper maps, it is cautioned that they are geographically imprecise and compilers adopted the convention of rounding them to the nearest minute. Geological Survey are appreciated.

    Weak to moderate sericitization reported in, or near, some deposits in Nevada. Plain Language Summary, not published This data set depicts the spatial distribution and most significant geological attributes of the world's most important sediment-hosted, stratiform copper mineral deposits.

    Witherite is a desirable source of barium chemicals because it is soluble in acid, but it is not suitable for applications where inertness in acid environments is important.

    The Cirque deposit in British Columbia, represents the middle of this spectrum and consists of interlaminated barite, sphalerite, galena and pyrite.

    Alternatively, these deposits could have formed by high temperature replacement of barite by witherite Turner and Goodfellow, Their lateral extent may be over several square kilometres. Lefebure of the B. Syndepositional faults are extremely important for SEDEX deposits that are commonly proximal to the vents, but may not be essential for all sediment-hosted stratabound barite deposits.

    Witherite, a barium carbonate, occurs as an accessory mineral in some barite deposits and rarely forms a deposit on its own.

    The chemical sediments change composition with distance from the vent reflecting changes in temperature and other parameters of the hydrothermal fluid as it mixed with seawater. Two additional service tables: dbversion and unitcvsn, provide the title, version and authors of the current database, and conversion factors to metric for the production and resource figures, respectively.
