Description
Four stratigraphic sections were measured to document the vertical stacking of
stratigraphic units and the lateral relationships between beds at the Sleeping Giant Ridge
exposure.
Individual beds at this location are predominantly S3 beds with Tc, and rare S1 beds
(Figure 2.18) that have wavy or scoured bases that comprise the coarse and medium
grained sand beds of Facies 2, 3 and 4, (Figure 2.20). In addition Tb, Td and Te make up
the cm scale, interbedded sand, silt and mud beds that comprise Facies 5 (Figure 2.21).
Coarser grained beds of Facies 3 and 4 overlying finer grained beds of Facies 5 load into
the finer grained beds resulting in soft sediment deformation features such as flame
structures (Figure 2.22). The coarsest grained beds of Facies 2, 3 and 4 comprise the
channel axis fill (Schwarz and Arnott, 2007) and the thin bedded turbidites of Facies 5
laterally inter finger with the channel fill facies associations and represent the margins of
the channels or local levees (Deptuck, 2003) (Figures 2.7). Up to 6 channel elements as
defined by Sprague (2002) comprise Facies 1, 2, 3 and 4 channel fill and Facies 5 channel
margin deposits at this location (Figure 2.18). These stacked channel elements form a
portion of a channel complex as defined by Sprague (2002).
