|Location and accuracy||Location plotted is locality 110 (sample 50ATr160) from original 1950 field notes and maps of Tailleur and cited in Patton and Matzko (1959, p. 12), in T11S, R24W; on north flank of Mt. Bupto about 0.5 mi (0.8 km) north of summit; located to within 1 mi (1.6 km).|
Geologic descriptionPhosphatic mudstone in dark-colored, dominantly calcareous rocks of the Carboniferous Lisburne Group, probably from a stratigraphic level correlative with the black chert and shale member of the Alapah Limestone. Nearby dolostone talus derived from Mt. Bupto has purple and green fluorite and coarsely crystalline calcite fracture coatings.
