Abstract

Probable lithified beachrock has been examined in sediments of Permian, Paleocene, Eocene and Miocene age. Brief, general descriptions of several of these exposures are given. The name, Lagunita, is applied to a Permian beachrock in New Mexico. Lithified beachrock may be mistaken for travertine, limestone conglomerate, intraformational conglomerate, and tectonic breccias. The presence of beachrock does not necessarily indicate the position of a continental shoreline.
