Geomorphology of the Sierra of Santa Catarina, D.F., Mexico

Abstract

The Sierra of Santa Catarina, located to the east of Mexico city, consists of an ENE trending group of Quaternary volcanic cones and associated lava flows. It covers an area of approximately 75 km² and is surrounded by the lacustrine plain of the Basin of Mexico. This area is represented in detail on a large scale geomorphological map, which shows a total of 37 relief elements that are divided into the following categories: endogenous (volcanic: explosive, effusive and explosive-effusive), endogenous-eroded (volcanic erosive), and exogenous (erosive, cumulative and anthropic). The geomorphological cartography represents the relief in the year 1990; it has been modified since then by the extraction of material, which is leading to the destruction of all the volcanic cones. Volcanism migrated from west to east and is represented by six morphogenetic scoria cones, an andesitic dome anda maar... In order to continue, download full text in PDF.
