    Petrophysical measurements on core plug samples of sediment core CRP-1 (Table 1) (1998)
    PANGAEA
    In:  Supplement to: Brink, Jason; Jarrard, Richard D (1998): Petrophysics of core plugs from CRP-1 drillhole, Victoria Land Basin, Antarctica. Terra Antartica, 5(3), 291-297, hdl:10013/epic.28342.d001

    Description: This paper reports measurements of velocity vs pressure and of bulk density, porosity, matrix density, and magnetic susceptibility in 18 core plugs from CRP-1. Comparison of our bulk densities with continuous whole-core density records shows very good agreement. Core-plug measurements of matrix density permit conversion of the whole-core density record to porosity. Agreement between our magnetic susceptibility measurements and the continuous, whole-core data is excellent. In contrast, our atmospheric pressure measurements of P-wave velocity are ~10% faster than whole-core data obtained at the same pressure. Our measurements of velocity versus pressure indicate that in situ P-wave velocities are probably only 1-3% higher than those measured at atmospheric pressure. Although the Miocene section has undergone significant exhumation, we do not observe typical exhumation signatures of anomalously low initial velocities followed by microcrack closing as pressure is increased. Instead, velocity response to pressure appears to be dominated by a small amount of post-exhumation cementation.

    (Table 1) Bulk and grain density, porosity, and p- and s-wave velocity characteristics of ODP Hole 163-990A sediments (1999)
    PANGAEA
    In:  Supplement to: Cerney, Brian; Carlson, Richard L (1999): The effect of cracks on the seismic velocities of basalt from Site 990, Southeast Greenland margin. In: Larsen, HC; Duncan, RA; Allan, JF; Brooks, K (eds.) Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 163, 1-7, https://doi.org/10.2973/odp.proc.sr.163.106.1999

    Description: Seismic velocities in rocks are influenced by the properties of the solid, the pore fluid, and the pore space. Cracks dramatically affect seismic velocities in rocks; their influence on the effective elastic moduli of rocks depends on their shape and concentration. Thin cracks (or fractures) substantially lower the moduli of a rock relative to the effect of spherical voids (or vesicles), and lower moduli are reflected by lower P- and S-wave velocities. The objective of this research is to determine the types and concentrations of cracks and their influence on the seismic properties of subaerially erupted basalts drilled from Hole 990A on the Southeast Greenland margin during Ocean Drilling Program Leg 163. Ellipsoidal cracks are used to model the voids in the rocks. The elastic moduli of the solid (grains) are also free parameters in the inverse modeling procedure. The apparent grain moduli reflect a weighted average of the moduli of the constituent minerals (e.g., plagioclase, augite, and clay minerals). The results indicate that (1) there is a strong relationship between P-wave velocity and porosity, suggesting a similarity of pore shape distributions, (2) the distribution of crack types within the massive, central region of aa flows from Hole 990A is independent of total porosity, (3) thin cracks are the first to be effectively sealed by alteration products, and (4) grain densities (an alteration index) and apparent grain moduli of the basalt samples are directly related.
