Local section: | Army Camp Beach | ||||
Regional section: | San Nicholas Island | ||||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: Dune sand and fossiliferous marine terrace deposits of Quaternary age. These overlie Eocene strata. Fossils come from seven well-developed wave-cut platforms at altitudes of 25 to 990 feet. Several submerged terraces are present on the shelf adjacent to the island., the lowest being 400 ft below sea-level. Presumably all the terrace platforms on San Nicholas Island were cut later than the middle Pleistocene diastrophism recognized elsewhere in southern California. Terrace platforms are covered with a variety of sediments of marine and non-marine origin and range in thickness from a few inches to many feet. |
Lithology and environment
Primary lithology: | pebbly,shelly/skeletal conglomeratic,calcareous sandstone |
Includes fossils? | Y |
Lithology description: Generally comprise poorly sorted calcareous sand and gravel composed primarily of mollusc shell fragments, echinoid plates and spines, calcareous algae, and bryozoans. | |
Environment: | coastal indet. |
Glacial or sequence phase: | transgressive systems tract |
Geology comments: Higher emergent terraces may represent wave-abraded platforms that were eroded during eustatic changes in sea level combined with tectonic uplift. The lowest emergent terrace may have been cut during eustatic sea-level changes followed by very slight regional seaward warping. Presumably all the terrace platforms on San Nicholas Island were cut later than the middle Pleistocene diastrophism recognized elsewhere in southern California |
