Análisis morfotectónico de las depresiones de Ixtlahuaca y Toluca, México

Abstract

An analysis of the recent tectonic activity usin gegcomorphologic evidence and resulting morphotetonic maps are presented. Blocks and faults characterized by different in ten sities of tectonic activity are shown in the maps, as well as other eomplementary relief elemcnts. The exjstence of a probably unknown regional lineament is inferred and a portion of upheaved lacustrine dcposits is detected. Finally, an attempt of a relative fault chronology is established.
