IODP Expedition 375 Site U1520 Unit IV fault and stylolite frequency and texture observations

Leah, Harold

British Geological Survey

(2019)

Descriptions

Data are either (1) depths and spacings between stylolites and faults within Unit IV, (2) images from IODP drill core image logs of the locations of samples observed, (3) photomicrographs and flatbed thin section scans of thin sections cut from samples, (4) SEM BSE or EDS data collected at Cardiff University. These data form the basis of: Leah et al. "Brittle-ductile strain localisation and weakening in pelagic sediments seaward of the Hikurangi margin, New Zealand", Tectonics, Submitted. Images and data from samples collected at IODP Expedition 375 Site U1520 (38°58.1532ʹS, 179°7.9112ʹE, 3522.1 mbsl). This is just seaward (east) of the trench of the Hikurangi Margin, New Zealand.
