Palmer Deep, on the inner continental shelf southwest of Anvers
Island off the Antarctic Peninsula, is a glacially overdeepened basin
consisting of three subbasins. Two sites, 1098 and 1099, were drilled in
the Palmer Deep area.
A high-resolution porosity curve has been calculated from density
data and subsequently plotted against the shipboard lithologic logs.
These new data correspond accurately to the lithologic logs, magnetic
susceptibility, and gamma ray attenuation (GRA) density data and offer
information on the heterogeneity of the sediments.
Petrophysical groups have been generated to investigate interrelationships
between different physical attributes. To develop these petrophysical
groups, crossplots of the available physical properties data
were performed. The results for the GRA density and magnetic susceptibility
crossplots demonstrate distinct clusters. Plotting the magnetic
susceptibility and GRA density data logs (divided into these new petrophysical
groups) against lithology provided information to subdivide
the lithologic unit(s) into a series of petrophysical units
