Cerro los Pinos (Miocene of Chile)

Also known as Laguna del Laja

Where: Bío Bío, Chile (37.5° S, 71.2° W: paleocoordinates 38.0° S, 67.3° W)

• coordinate estimated from map

• local area-level geographic resolution

When: Cura-Mallín Formation, Middle Miocene (16.0 - 11.6 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; volcaniclastic, sandy mudstone and volcaniclastic, conglomeratic sandstone

• Our analyses indicate that the exposed thickness of the Cura-Mallin Fm southeast of Laguna del Laja exceeds 1800 m, consisting of interbedded predominantly-fluviatile volcaniclastics with minor facies

•possibly indicative of short-lived lacustrine phases

• Volcaniclastic mudstone and sandstone

•Pebble conglomerate and trough cross-bedded volcaniclastic sandstone

Size class: macrofossils
