| Resumo |
Samples obtained in Hole 803D for shipboard determination of index properties were analyzed to determine their microfossil constituents. The resulting data are compared to shipboard-measured physical properties data to assess the relationships between small-scale fluctuations in physical properties and microfossil content and preservation. The establishment of relationships involving index properties of these highly calcareous sediments is difficult because of the role of intraparticle porosity. Relationships were observed between calculated interparticle porosity and microfossil content. Impedance, calculated using bulk density based on interparticle porosity, exhibits an increase with increasing grain size. Variations in the coarse fraction constituents appear to exert more control over physical properties than variations in the fine-fraction constituents, although the fine fraction make up greater than 85% of the samples by weight. |
