(Table 1) Stable oxygen and carbon isotope composition of bivalve shells of s...
Bivalve shells from the CRP-l drillhole, Cape Roberts (Victoria Land Basin), have been analysed for their stable isotope composition to obtain information on Antarctic coastal... -
Characterisation of breccias in sediment core CRP-1 (Table 1)
CoreScan images were examined to determine the origin of breccias in the CRP-1 core. Breccias occur throughout the core. but are dominant deformation features in the upper 85 m.... -
Micromorphological observations in the Miocene section of sediment core CRP-1...
Five samples of diamicts from different levels of the Miocene part of the CRP-1 core have been thin sectioned. Observations in the thin sections relate to texture, diagenesis,... -
Distribution of Miocene benthic foraminifera of sediment core CRP-1 (Fig. 1)
The analysis of foraminifera from the Miocene section of the CRP-1 drillhole (Ross Sea, Antarctica) revealed the presence of poor to moderate rich and diversified assemblages.... -
Abundance of phytoliths in sediment core CRP-1 (Table 1)
This report documents phytoliths (siliceous plant fossils) in 16 samples from the Cape Roberts Project core (CRP-1), including the first record of two phytolith forms from... -
Modal analyses of thin-sections of sediment core CRP-1 (Table 1)
During the course of the 1997 drilling campaign, lithostratigraphic boundaries were assigned to the CRP-l core on the basis of perceived changes in lithology. The geologically... -
Miocene siliceous microfossil occurence of sediment core CRP-1 (Table 3)
Lower Miocene diatoms and other siliceous microfossils in the Cape Robcrts Project drillcore (CRP-l), Roberts Ridge, western McMurdo Sound, are documented. Diatom... -
Description of lithofacies associations and their interpreted settings from s...
Cape Roberts Project drillcore 1 was obtained from Roberts Ridge, a sea-floor high located at 77°S, 16 km offshore from Cape Roberts in western McMurdo Sound, Antarctica. The... -
Sample information and classification of lower Miocene gravity-flow types of ...
Nineteen samples of the Cape Roberts-1 drillcore were taken from Miocene- age deposits, from 90.25 – 146.50 metres below seafloor (mbsf) for thin section and laser grain-size... -
Occurence of macrofossils in the carbonate-rich unit of sediment core CRP-1 (...
Macrofossils are a significant component of biogenic carbonate sediments in the Quaternary section of the CRP-1 drillhole, Cape Roberts, Victoria Land Basin. The middle... -
Carbonate content of sediment core CRP-1 (Table 1)
Determinations of total carbonate content yield additional information, in the context of integrated investigations, thus enabling or enhancing the interpretation and... -
Occurence of marine palynomorphs of sediment core CRP-1 (Table 1)
The first core of the Cape Roberts Project, CRP-1, penetrated a Quaternary and lower Miocene section rather than the anticipated Palaeogene sediments. Initial palynologic study... -
Petrographical classification and mineral assemblage of basement clasts from ...
Petrographical and mineral chemistry data are described for the mist representative basement lithologies occurring as clasts (pebble grain-size class) from the CRP-1 drillhole.... -
(Table 1) Detrital modes for sand grains in sediment core CRP-1
Detrital modes for the sand-size fraction in 24 samples from the CRP-1 drillcore are described. Most samples are largely composed of quartzo-feldspathic detritus sourced... -
Rare earth element content of the clay fraction from sediment core CRP-1 (Tab...
TEM observations on smectites and REE analyses on the clay minerals of the sediments of CRP-1 core were carried out to investigate their origin and the source rocks from which... -
Abundance of terrestrial palynomorphs of sediment core CRP-1
Sparse pollen and spores from the lower Miocene section of CRP-1 derive from at least three sources. A low-diversity but persitent angiosperm-moss-liverwort assemblage may... -
Summary of 40Ar/39Ar results from core sediment CRP-1 (Table 1)
40Ar/39Ar dating of volcanic clasts and pumice provide constraints for depositional ages of the CRP-1 core. Laser-fusion analyses of anorthoclase phenocrysts from pumice clasts... -
Selected major elements and trace elements of ferrar dolerite clasts from sed...
One of the objectives of the Cape Roberts Project is to study the tectonic history of the western Ross Sea region. Timing of the uplift of the Transantarctic Mountains, which... -
Geochemistry on sediment core CRP-1 (Table 1)
The CRP-1 core penetrated 148 m of Quaternary and lower Miocene glacigenic sediments. This material complements the Eocene trhough Miocene strata that was cored previously at... -
Analytical results of 19 amino acid analyses from Unit 3.1 of sediment core C...
Amino acid-based geochronological analyses were carried out on fossil mollusc shell and foraminifera from Unit 3.1, Cape Roberts Project core CRP-1. Ratios of D-alloIsoleucine...
