Description:
Abstract:
This dataset contains location, geologic and mineral economic data for world rare earth mines, deposits, and occurrences. The data in this compilation were derived from published and non-published sources. Geographic coordinates are provided for 577 of the 799 deposits described here.
Purpose:
This dataset was compiled for the University of Arizona's Center for Mineral Resources Rare Earth monograph, a summary document intended to reflect our current knowledge of the geology and mineral economics of the rare earths, including yttrium.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The accuracy of file data attributes is highly variable, especially for some parts of Africa and Asia. Most locations are believed to be within 2-5 minutes of the exact location; some locations are for the nearest town, and other locations are of undetermined accuracy. Location errors are a result of inadequate or incorrect original data, error caused by multiple locations with the same name, and error introduced by data entry or location format conversion. The data tables were spot-checked against the original data.
Logical_Consistency_Report: Point data are given in degrees and minutes.
Completeness_Report:
This report is the most complete compilation of rare earth mines, deposits, and occurrences known. However, it is highly likely that there are additional occurrences of rare earths that are not included. In addition, data for many of the sites are incomplete. Determination of latitudes and longitudes for some sites were impossible given the available data.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The latitudes and longitudes were largely taken from Published data or determined from descriptions of the location using the maps available to us or internet-based gazeteers such as the GEOnet Names server on the National Imagery and Mapping Agency's database. The accuracy of these locations varies with the detail of the original information.
