The Tecpan regional fault: evidence for major ne lineaments

Abstract

Several published works about the continental margin structure in southem Mexico were reviewed in order to find a possible connection of on- and offshore morphotectonic features. From a regional view, twelve local geological features are combined to suggest the presence of major structural lineament, the Tecpan Regional Fault. This fault is an element of the Mexican Volcanic Belt fault or rift system which has been suspected by others. This structure runs from the inner slope of the Middle American Trench to the Mexican Volcanic Belt system with a N 17° E strike.
