no samples that represent lower porosities (less than 0.45) of the siliceous oozes and

therefore the predicted relationship should be used with caution at lower porosities.

 The lack of correlation exhibited between permeability and porosity in calcareous

oozes suggest that one should consider other variables such as depth, consolidation rates

and relative age of the sediment to obtain meaningful relationships for pelagic sediments.

According to Bryant et al. (1981), unlike grain size, the influence of calcium carbonate is

more pronounced with increasing depth because as burial increases less reduction of

porosity is observed for calcareous sediments compared to non-calcareous sediments.

Mechanical compression tests conducted by Terzaghi (1940) and Robertson (1967)

demonstrated that calcareous muds compact less than non-calcareous muds. A similar

study by Bryant et al. (1981) demonstrated that under a similar load, carbonate sediments

do not consolidate to as low a void ratio as non-carbonates. Based on this finding they

speculated that the resistance towards consolidation in carbonates could be a result of the

relative age of the sediment or the differences in particle shape or the structural strength

of the individual particles.

 Even though comparison of underthrust/incoming and prism/decollement structural

domains from Group 2 suggested the possibility of different varying permeability-

porosity relationships, it is recommended to further investigate these relationships using

more samples; the results presented here are based on a limited number of samples

especially those represented by the prism/decollement group. It would be worthwhile to

further test the effects of structural domain on permeability-porosity relationship, as this

information will allow future studies based on permeability-porosity relationships to

more realistically represent fluid flow.
