Marine palynomorph abundance estimates of sediment core CRP-2A (Fig. 2)
A diverse assemblage of marine palynomorphs was recovered from the Oligocene - Miocene section of CRP-2/2A. Most of the assemblage is composed of previously unrecognised... -
Lithology description, textural and structural observations, and indications ...
From the upper 300 m of CRP-2/2A, twenty-six samples of diamicts and deformation structures have been thin sectioned. These have been analysed for texture, structure, diagenesis... -
Occurence of foraminifera and other microfossils in sediment core CRP-2/2A (T...
Sparse to moderately abundant foraminiferal assemblages from Oligocene and Lower Miocene sediments in the CRP-2/2A drillhole contain C.27 genera and 42 species of calcareous... -
Summary of 40Ar/39Ar results from sediment core CRP-2A (Table 1)
40Ar/39Ar analyses of tephra and clasts of volcanic rock provide age constraints for upper parts of the CRP-2A core. Single-crystal laser-fusion analyses of anorthoclase... -
(Table 1) Detrital modes for sand grains in sediment core CRP-2/2A
Dynamic provenance variations are deduced from sand-grain detrital modes in samples obtained from the CRP-2/2A drillcore. Below an important unconformity at 307 metres below sea... -
Chronostratigraphy of sediment core CRP-2/2A (Table 1)
The 624.15 m glaciomarine sedimentary succession recovered in the CRP-2/2A drillcore comprises lower Oligocene (1000 m/m.y.). Between 306.65 mbsf and the bottom of the drillcore... -
Distribution of foraminifera, pre-Pliocene foraminifera and macrofossil debri...
The stratigraphic distribution, assemblage content, paleoecology and age of foraminifera recovered in fourteen of sixteen samples from the 5.63 m thick CRP-2 (Lithostratigraphic... -
Range chart of calcareous nannofossils in sediment core CRP-2A (Table 1)
Rare calcareous nannofossils from the Cape Roberts Project drillhole CRP-2A indicate that this area was episodically invaded by marginal oceanic surface waters during the late... -
Prominent deformation features and interpretation of sediment core CRP-2/2A (...
Sediment deformation features in CRP-2/2A were described during normal logging procedures and from core-scan images. In this paper the origin of soft-sediment folding, contorted... -
Sample intervals and carbonate content of sediment core CRP-2/2A (Table 1)
Determinations of total carbonate contents on CRP-2/2A cores yield additional information and knowledge, thus enabling or enhancing the interpretation and characterization of... -
Element abundances, loss on ignition, total analyzed abundances, CIA values, ...
The CRP-2/2A core, drilled in western McMurdo Sound in October and November 1998, penetrated 624 m of Quaternary. Pliocene, lower Miocene, and Oligocene glacigenic sediments.... -
Major and trace element concentrations of sediment core CRP-2/2A (Table 1,2)
Bulk chemistry (major and trace elements) of sand-sized samples from the CRP-2/2A drillhole provides evidence for a multicomponent provenance with changes in the component... -
Cenozoic terrestrial palynomorphs from the late Oligocene to early Miocene se...
Sparse terrestrial palynomorphs (spores and pollen) were recovered from glacigene Lower Miocene and Oligocene core samples from the Cape Roberts Project (CRP) drillhole... -
Average dip directions from intervals of dipmeter log in drill hole CRP-2A
Bedding dips in the CRP-2A drillhole were determined in two ways (1) analysis of a dipmeter log, and (2) identification of bed boundaries on digital images of the outer core... -
Carbon and nitrogen of sediment core CRP-2A (Table 1)
Sediments and rocks recovered in CRP-2/2A coring operations contain relatively little organic matter (average TOC=0.28%) and very small amounts of solvent-soluble organic... -
Temperature and resistivity profile of drill hole CRP-2A
In the northern part of McMurdo Sound (Ross Sea, Antarctica), drillhole CRP-2/2A targeted he western margin of the Victoria Land basin to investigate Neogene to Palaeogene... -
Core derived downhole logs for holes CRP-2 and CRP-2A
In the northern McMurdo Sound (Ross Sea, Antarctica), the CRP-2/2A drillhole targeted the western margin of the Victoria Land Basin to investigate Neogene to Palaeogene climatic... -
Clay and smectite analysis of sediment core CRP-2A
Sediments of the CRP-2/2A drill core from the continental shelf of McMurdo Sound in Ross Sea, Pacific sector of the Southern Ocean, have been investigated for their clay mineral... -
Distribution of the main heavy minerals identified in sediment core CRP-2/2A
Heavy minerals from the lower Oligocene to Quaternary sediments of the CRP-2/2A drill core have been analysed in order to characterize the mineralogical composition of the... -
Physical properties of sediment core CRP-2A
In this paper the relationship between whole-core compressional wave velocities and gamma-ray attenuation porosities of sediments cored at CRP-2/2A is examined, and compared...
