Information leading to the delineation of this focus area

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 Unknown.
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.
