Description:
Abstract:
This spatial database of evaporite-related potash deposits and occurrences provides location and descriptive information for 981 deposits and occurrences that are considered useful and (or) significant in assessing potash resources around the world. The database contains location, geologic, and some limited economic data, as well as one or more references for each site.The spatial database was created for use in a geographic information system (GIS) to support a global potash resource assessment by the U.S. Geological Survey. The purpose of this world-wide inventory is to document the geologic occurrence of (1) rocks enriched in water-soluble potassium minerals and (2) naturally-occurring brines enriched in potassium. Potash, as used in this report, refers to potassium-bearing minerals, ores, and processed products. Databases that summarize the distribution of known occurrences and their geologic setting are an integral part of a geologically-based evaluation of undiscovered mineral resources. The distribution of known occurrences allows us to understand the factors which control their distributions and to forecast areas with potential. These deposits and occurrences also serve as analogs for the types of resources that may be present; the size and composition of undiscovered deposits is likely to be similar to those that have been found.
Purpose:
Spatial and descriptive data for 981 evaporite-related potash deposits and occurrences around the world are stored in the shapefile "PotashDeps" for use in a geographic information system (GIS).

Use_Constraints:
There are no use limitations for this item. The U.S. Geological Survey (USGS) provides these geographic data "as is." The USGS makes no guarantee or warranty concerning the accuracy of information contained in the geographic data. The USGS further makes no warranties, either expressed or implied as to any other matter whatsoever, including, without limitation, the condition of the product, or its fitness for any particular purpose. The burden for determining fitness for use lies entirely with the user. Although these data have been processed successfully on computers of the USGS, no warranty, expressed or implied, is made by the USGS regarding the use of these data on any other system, nor does the fact of distribution constitute or imply such warranty. Locations for deposits and occurrences were derived from a variety of source maps, the smallest scale of which was about 1:1,000,000; thus, these data should not be used or portrayed at scales larger than 1:1,000,000 (for example, 1:500,000).

Data_Set_Credit:
Greta J. Orris, Mark D. Cocker, and Jeffrey C. Wynn compiled the raw data into a spreadsheet format; Greta J. Orris designed the data model, standardized the data content, and proofed location information; Pamela Dunlap converted the data from a spreadsheet format to a spatial database, further standardized the data, wrote metadata, and prepared the digital data for publication.

Process_Step:
Process_Description:
Spatial and descriptive data were imported from a Microsoft Excel spreadsheet format into an Esri File Geodatabase feature class of points (vector GIS). Locations were proofed with respect to the item COUNTRY using a shapefile of political boundaries (U.S. Department of State, 2009). Attributes were further standardized and corrected in the feature class attribute table. Attributes were also proofed to make sure that data were not truncated in the conversion process.
