Deposit model for closed-basin potash-bearing brines
Closed-basin potash-bearing brines are one of the types of potash deposits that are a source of potash production within the United States, as well as other countries. Though these deposits are of highly variable size, they are important sources of potash on a regional basis. In addition, these deposits have a high potential of co- and by-product production of one or more commodities such as lithiAuthorsGreta J. OrrisCarbonatites of the world, explored deposits of Nb and REE— Database and grade and tonnage models
This report is based on published tonnage and grade data on 58 Nb- and rare-earth-element (REE)-bearing carbonatite deposits that are mostly well explored and are partially mined or contain resources of these elements. The deposits represent only a part of the known 527 carbonatites around the world, but they are characterized by reliable quantitative data on ore tonnages and grades of niobium andAuthorsVladimir I. Berger, Donald A. Singer, Greta J. OrrisGeology and Nonfuel Mineral Deposits of Africa and the Middle East
A nation's endowment of nonfuel mineral resources, relative to the world's endowment, is a fundamental consideration in decisions related to a nation's economic and environmental well being and security. Knowledge of the worldwide abundance, distribution, and general geologic setting of mineral commodities provides a framework within which a nation can make decisions about economic development ofAuthorsCliff D. Taylor, Klaus J. Schulz, Jeff L. Doebrich, Greta Orris, Paul Denning, Michael J. KirschbaumLimestone - A Crucial and Versatile Industrial Mineral Commodity
Limestone, as used by the minerals industry, is any rock composed mostly of calcium carbonate (CaCO3). Although limestone is common in many parts of the United States, it is critically absent from some. Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an enormous array of other products, making it a truly versatile commodity. Portland cement is essential tAuthorsJames D. Bliss, Timothy S. Hayes, Greta J. OrrisPreliminary non-fuel mineral resource assessment of Afghanistan 2007

A substantial reservoir (up to 1 kg ha-1) of natural perchlorate is present in diverse unsaturated zones of the arid and semi-arid southwestern United States. The perchlorate co-occurs with meteoric chloride that has accumulated in these soils throughout the Holocene [0 to 10−15 ka (thousand years ago)] and possibly longer periods. Previously, natural perchlorate widely believed to be limited to tAuthorsBalaji Rao, Todd A. Anderson, Greta J. Orris, Ken A. Rainwater, Srinath Rajagopalan, Renee M. Sandvig, Bridget R.

Introduction As part of the assessment of lacustrine diatomite resources in the Western United States (fig. 1), U.S. Geological Survey (USGS) project members conducted a review of literature relating to the formation, location, and nature of deposits in the study area. This preliminary bibliography consists of selected publications to identify, locate, and describe the deposits to be studied, tAuthorsKaren S. Bolm, Alan R. Wallace, Phillip R. Moyle, James D.
