Abstract
Origin of the Cabo Rojo Beach-Ridge Plain, Veracruz, Mexico
Frank W. Stapor, Jr. (1)
ABSTRACT
The Cabo Rojo beach-ridge plain was formed in a low-energy shadow behind the Blanquilla-Lobos coral-reef tract. The source of the sand comprising Cabo Rojo was offshore material of Wisconsin (?) age, most probably deposited by the Rio Panuco during a lower sea-level stand. Islands within the Laguna de Tamiahua define a sand body similar in shape and orientation to that of Cabo Rojo, strongly suggesting either a 2-stage Holocene constructional history, or the remains of a pre-Wisconsin barrier.
The beach-ridge plain consists of low, hummocky ridges (relief less than 1 meter, spacing of 100 meters) oriented parallel to the present-day coast. This coast now is undergoing erosion and beach ridges are not forming. Cliffed back-beach dune ridges are found on the northern and southern portions of Cabo Rojo, the northern ridges being best developed. Long-shore drift compartmentalization has been effected along this coast by the Blanquilla-Lobos offshore reef tract.
