Belted Range, Carrara Fm, Red Pass Limestone Mbr. (Cambrian of the United States)

Where: Nevada (37.3° N, 116.1° W: paleocoordinates 2.0° S, 94.0° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Albertella trilobite zone, Red Pass Limestone Member (Carrara Formation), Delamaran (511.2 - 506.5 Ma)

• The upper few meters of the member are locally rich in trilobites of the Zacanthoidid Zonule of the Albertella Zone (p. 59) in the Groom Range and the Nevada Test Site.

Environment/lithology: lagoonal or restricted shallow subtidal; lime mudstone

• The Red Pass Limestone Member generally forms a

•prominent cliff and consists of burrowed, oncolitic, and

•skeletal-fragment lime mudstones, oolite, and a variety of

•laminated lime mudstones and fenestral limestones.
