Abstract
During the course of a reflexion survey of an area in Southwest Texas,
a group of seismograms was obtained on which were recorded a number
of events having abnormal apparent velocities. The dips computed
from these events on the assumption that they were conventional reflexions
in the plane of the profile were much larger than the anticipated
stratigraphic dip. This paper presents a discussion of the possible
origins of these events and an analysis which affords considerable
evidence that they originated on fault planes.
