Laser-derived, particle size data from CRP-2/2A: implications for sequence and seismic stratigraphy

first_imgGravel-free, high-resolution (1-metre spacing, 32 channel) particle size data from theCRP-2/2A drill core indicate that many of the diamictites were likely deposited from floatingice. Textural dislocations occur at most sequence boundaries and provide independentcorroboration of the sequence stratigraphic interpretation. Likewise the data largely support thecorrelation drawn (Fielding et al., this volume) between the sequence stratigraphic cycles andthe regional seismic stratigraphy (an alternative correlation to Reflector ‘f’ is also suggested).The gravel-free data appear to be reflecting predominantly regional (global?) forcing with somepossible local effects, and long-term trends persisting through gravelly textural dislocations.last_img read more
