Publication_Date: 2009 Title: Carbonatites of the world, explored deposits of Nb and REE Series_Information: Series_Name: Open-File Report Issue_Identification: 2009-1139 Publication_Information: Publication_Place: Menlo Park, California Publisher: Geological Survey (U.S.) Online_Linkage: https://doi.org/10.3133/ofr20091139 Online_Linkage: https://mrdata.usgs.gov/carbonatite/ Description: Abstract: Data on 60 of the 527 known carbonatites in the world, providing reliable quantitative data on ore tonnages and grades of niobium and REE. Purpose: Assist in the creation of descriptive and grade-tonnage models for mineral deposits to support a new national mineral resource assessment. The models used for such an assessment must be based on information that is available for undiscovered deposits, including lithology, age, structural features, and geophysical and geochemical anomalies that are visible on regional geologic maps rather than the detailed studies commonly carried out on deposits that are well known.

Grade and tonnage data are available to varying degrees for districts, deposits, and mines. For the deposits in this model, the following rule was used to determine which ore bodies were combined. All mineralized rock or altered rock within two (2) kilometers was combined into one deposit. Some examples illustrate the effects of the application of this rule: (1) Salitre I and II deposits in Brazil and (2) Upper Fir and Fir in Canada. Carbonatite deposits are remote from one another Completeness_Report: 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 and REE.
