Basis for focus area |
Carbonatites; mining district outlines from McLemore (2017). |
Identified resources |
Historical production of barite. |
Production |
Barite produced in 1979-1980. |
Status |
Past mining and exploration (NMBGMR has drill core). |
Estimated resources |
Unknown. |
Geologic maps |
McLemore (1980, 1982a), various scales; Chamberlin (1982), scale 1:12,000. |
Geophysical data |
Inadequate aeromagnetic and aeroradiometric coverage. |
Favorable rocks and structures |
Carbonatite intrusions as well as adjacent contact metasomatic fenites. |
Deposits |
Box Canyon prospect (MRDS dep_id: 10012385). |
Evidence from mineral occurrences |
MRDS. |
Geochemical evidence |
See McLemore (1982a, 1983); McLemore and others (2020). |
Geophysical evidence |
None. |
Evidence from other sources |
Unknown. |
Comments |
The carbonatite dikes have been mapped by McLemore (1980, 1982a), but detailed mineralogy and chemistry are still needed. Also geophysical data are required to identify subsurface extent. Drill core at NMBGMR. |
Cover thickness and description |

Authors |
Virginia T. McLemore, Joshua M. Rosera. |
New data needs |
REE chemistry on carbonatites, digitization of geologic maps. |
Geologic mapping and modeling needs |
Part of state map, digitize McLemore (1982a), which shows more detail than Chamberlin (1982). |
Geophysical survey and modeling needs |
High resolution geophysical coverage needed (geophysical survey request completed). |
Digital elevation data needs |
Lidar complete. |
