ABSTRACT
stratigraphic
response
to differential tectonic subsidence. Because the water volume of a lake
is finite, tilting of the valley floor redistributes the lake water. If
the lake water level is below a hinge point (fulcrum) that experiences
no net subsidence, the lake shoreline is translated toward the site of
subsidence, and a deeper lake forms. This tectonostratigraphic
model
for
rift-lake sedimentation is tested in a
seismic
and sequence
stratigraphic
study of deltaic and lacustrine deposits that accumulated in a Cenozoic
extensional basin beneath Goshute Valley, Nevada.
Seismic
sequences exhibit
an internal, cyclic stacking hierarchy of
seismic
reflections interpreted
as the
stratigraphic
response of a lowstand paleolake to tectonism (forced
regression) and subsequent lake level restoration (transgressive and highstand
systems tracts).
