Salada Fm, Refugio, Mexico - Beal (1948) (Pliocene of Mexico)

Also known as Refugio, San Jose del Cabo

Where: Baja California Sur, Mexico (24.8° N, 111.7° W: paleocoordinates 24.6° N, 110.4° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Salada Formation, Pliocene (5.3 - 2.6 Ma)

• Rocks are mapped as Pliocene, but may in fact be Pleistocene. They lie directly upon the crystalline focks or on the underlying formation believed to be Ysidro in age. The strata appear to consist of several hundred feet of strata, the lower part of which is brown sandstone and the upper part white sandstone. Posssibly outcrops described as Salada Fm are not all the same age, yet most appear to be Pliocene.

• bed-level stratigraphic resolution

Environment/lithology: marine; unlithified, brown, white sandstone

• Siliciclastic facies. No paleoenvironmental data reported.
• Consists of brown and white sandstone.

Size class: macrofossils

Collection methods: quarrying,

• Stated that fossils were collected. No repositories reported.
