Abstract:
Turbidite channel-levée complexes have been the focus of extensive research
from a number of modern and ancient deep-water turbidite systems over
more than fifty years. Although high-resolution 3D seismic studies have
recently yielded unprecedented imaging of these deposits, the internal
facies complexity of a channel-levée complex remains elusive. To fill this gap,
extensive well-exposed outcrops are particularly important, as they provide
information on fine-scale facies heterogeneity.
This contribution reports on the ongoing ‘Tachrift’ Project, which aims to
explore 9 superimposed channel-levée complexes belonging to the Tachrift
turbidite system (late Tortonian- early Messinian) of the Taza–Guercif Basin
(NE Morocco). Arid climate and deep incision by ephemeral streams make
for world-class, extensive, unexplored outcrops spread over an area of ~ 16
km2
. Preliminary results provide valuable insights into facies and geometry
of channel-fills and correlative levées over a ~150 m-thick and ~4 km wide
transect largely oblique to palaeoflow, which may contribute to improving
existing models of turbidite channel belt sedimentary heterogeneity and
stratigraphic evolution, applied to understand the composition of subsurface
analogues.
