New Pass Mine, Austin, Central Nevada (Triassic of the United States)
Where: Nevada (39.6° N, 117.5° W: paleocoordinates 8.1° N, 43.0° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Augusta Formation, Ladinian (242.0 - 237.0 Ma)
• group of beds-level stratigraphic resolution
Environment/lithology: reef, buildup or bioherm
• The regional setting of the New Pass Mine area during the Late Triassic was a broad shallow embayment in an arid region.
• The buildup was assigned to a mollusk-echinoderm grainstone facies and a coral-bivalve bindstone-packstone facies. An oolite-algal grainstone is found in direct contact with both the biofacies.
