    Anelastic strain recovery reveals extension across SW Japan subduction zone (2009)

    Description / Table of Contents: Sediment dominated convergent margins typically record substantial horizontal shortening often associated with great earthquakes. The convergent margin south of Japan is arguably one of the most extensively investigated margins and previous studies have documented extensive evidence for accretion and horizontal shortening. Here, we show results from anelastic strains recovered from three partially lithified sediment samples (~40% porosities) across the southwest Japan accretionary prism and propose that the margin is dominated by horizontal extension rather than compression. The anelastic strain results are also consistent with stress directions interpreted from two independent techniques - bore hole breakout orientations and core-scale fault data. We interpret this unexpected result to reflect geologically recent underthrusting of a thick sediment package and concomitant weakening of the decollément.

    Broad analysis reveals a consistent pattern of var gene transcription in Plasmodium falciparum repeatedly selected for a defined adhesion phenotype (2005)

    Notes: Transcription of the majority of the members of the Plasmodium falciparum var multigene family were analysed in two isolates by a quantitative approach. Both of these isolates had been repeatedly selected for adhesion to chondroitin sulphate A (CSA) and one had also been selected for adhesion to hyaluronic acid (HA). These adhesion phenotypes are expressed by many parasites isolated from placentae and are associated with malaria disease in pregnancy. Increased transcription of the var gene var2csa, or its homologue IT4 var4, was associated with the CSA and HA adhesion phenotypes in all parasites suggesting that it was the dominant, if not the only, var gene that encoded adhesion to CSA in these allogeneic isolates. Some var genes were consistently transcribed at higher levels than others regardless of expressed adhesion phenotypes suggesting a transcriptional hierarchy. Unspliced or partial transcripts were detected for most var genes tested. These atypical var gene transcripts may have implications for the regulation of var gene transcription.

    Description: X-ray computed tomography (CT) is a promising tool that yields data useful for understanding the fine-scale density structure of partly lithified and tectonically deformed sediments. We conducted 21 CT scans of ODP Leg 131 sediments, including whole-round cores and thin-section chips, obtained from the toe of the Nankai accretionary prism. The samples range from highly deformed pieces from the frontal thrust and décollement to homogeneous and essentially undeformed sediments above the frontal thrust and beneath the décollement. In the CT images, kink-like deformation bands and faults are recognized as obvious bright seams, bands, or stripes with relatively high linear attenuation coefficients. The differences in linear attenuation coefficients relative to the matrix range from 0.021 cm**2/g (kink-like deformation band) to 0.038 cm**2/g (fault). These data suggest a 0.10 g/cm**3 to 0.18 g/cm**3 increase in bulk density within the deformation structures, and they appear to be 13% and 33% more compacted than the nondeformed matrix, respectively. In contrast to the samples from the frontal thrust zone, CT images of the décollement sample exhibit relatively homogeneous textures. The attenuation coefficient of the sample of the décollement indicates bulk density and porosity values of 2.45 g/cm**3 and 18%, respectively. The sample, hence, is approximately 50% more compacted than the sediment outside the décollement zone.

    Description: This paper presents results of an interdisciplinary investigation of the relation between fluids, fluid flow, and deformation in the toe region of the Nankai accretionary prism. The techniques include thin-section petrography, SEM, TEM and microprobe analyses, and X-ray computed tomography as well as laboratory experiments. Together, the data suggest three structural/hydrologic regimes within the prism. These are: (1) the accreting sediments above the décollement zone, (2) the décollement zone, and (3) the underthrust sediments. The regime above the décollement is characterized by sediments that are progressively dewatered through both a penetrative fabric and a pervasive, but apparently poorly interconnected, set of core-scale deformation structures. The décollement is characterized by a relatively high density of structures/meter and is considered to be a regime of low stress but frequent failure. Hydrologically the décollement retards the vertical flow of fluids and enhances the potential for overpressuring in the footwall. Finally, the footwall regime contains very few tectonic structures and is structurally isolated from the stresses related to plate convergence. This regime provides an important component to the tectonics of the Nankai prism, however, because it supplies the overpressured fluids that cause the d?collement to fail at relatively low shear stresses.

    (Table 3) Main results of the stress tensor inversion of selected populations of slickenlined faults at OPD Hole 131-808C (1993)

    Description: Drilling at Site 808 (ODP Leg 131) provided an extensive record of the discrete brittle structures (small faults and shear bands) at the toe of the Nankai accretionary complex. Brittle failure is occurring throughout the hole, although most of the deformation has been observed between the frontal thrust and the décollement (from 365 to 963 mbsf). Brittle failure occurs in the turbiditic trench fill (0 to 600 mbsf) but also in the ash-bearing hemipelagites from the upper Shikoku Basin (600 to 800 mbsf) and the ash-free hemipelagites of the lower Shikoku Basin sequences, down to the décollement (963 mbsf). The geometry of the tectonic features has been recorded in a local frame related to the core liner and then corrected to an absolute frame by the use of paleomagnetic measurements. We used the resulting geometry of homogeneous populations of slickenlined faults to estimate the reduced stress tensor. The main result is to show three consistent stress patterns. Most of the fault clusters from the frontal thrust down to the décollement are in good agreement with a compressional regime with a northwest-trending sigma 1 (azimuth N305° to N315°). The compression direction is thus roughly parallel to the local direction of the relative convergence. It is also perpendicular to the trend of the anticlinal ridges. Discrete faults, locally appearing as clusters (e.g., 30 m above the décollement) agree with a quite different compression direction (west-southwest-east-northeast) and are restricted to the hemipelagic sequences above the décollement. They could be related to the heterogeneous internal deformation of this layer. Although isolated normal faults exist, their occurrence as clusters is restricted to the Shikoku Basin hemipelagic sequences and indicate a east-west to northwest-southeast extension axis (?3). Finally, the analysis of Mohr diagrams related to the best-fitting tensors shows some similarities and differences between the fault populations of the turbidite and those of the hemipelagite sequences. The angle of friction corresponding to 95% of the data is 30° +/- 5°, whereas including the remaining 5% in turbidites and hemipelagites would result in a lower friction angle (18° +/- 8°). The major difference concerns the angle between conjugate sets which are about 60° in the turbidites and lower (35°- 40°) in a 200 m thick zone above the décollement and can be explained by higher fluid pressure in the hemipelagites or by odd mechanical properties of this hemipelagic material.
