Sequence stratigraphic analysis of the CRP-1, Cape Roberts Project, McMurdo Sound, Antarctica
Vertical facies associations within the CRP- 1 drillcorc reveal a strong cyclicity
and facilitate the development of a sequence stratigraphic framework. The sedimentary
record appears to be punctuated by a series of erosional sequence boundaries which are here
inferred to be the product of cycles of glacial advance and retreat. This is further supported
by the absence of thick (preglacial) progradational sequences within the drill core. Eight
Miocene and at least two Quaternary sequences are identified on the basis of facies and
textural association. The core is dominated by transgressive (local glacial retreat) and high
stand (local glacial minimum) deposits, with regressive (local glacial advance) and
lowstand (local glacial maximum) events being under represented.
