Seismic interpreters must have a reliable methodology that allows them to (1) correlate seismic reflection events with well-log-defined sequence boundaries and (2) specify which seismic facies windows correspond to the rock facies intervals defined by well control.

This report details the occurrence, geometries, scarp morphology, and paleorupture histories of Quaternary faults of northwest Trans-Pecos Texas and northern Chihuahua, Mexico. This study area encompasses a part of the east margin of the Southern Basin and Range-Rio Grande rift tectonic province.
