A Late Cretaceous and Cenozoic reconstruction of the Southwest Pacific region: Tectonics controlled by subduction and slab rollback processes
TL;DR: In this article, a Cenozoic tectonic reconstruction is presented for the Southwest Pacific region located east of Australia, constrained by large geological and geophysical datasets and recalculated rotation parameters for Pacific-Australia and Lord Howe Rise-Pacific relative plate motion.
Journal ArticleDOI
Quartz fabrics in the Alpine Fault mylonites: Influence of pre-existing preferred orientations on fabric development during progressive uplift
TL;DR: In this article, strong quartz crystallographic preferred orientations (CPOs) were developed during dislocation creep in the mylonite zone exposed in the hanging wall of the dextral reverse Alpine Fault Zone, New Zealand.
Journal ArticleDOI
Structure and composition of the plate-boundary slip zone for the 2011 Tohoku-Oki earthquake.
Frederick M. Chester,Christie D. Rowe,Kohtaro Ujiie,James D. Kirkpatrick,Christine Regalla,Francesca Remitti,J. Casey Moore,Virginia Toy,M. Wolfson-Schwehr,Santanu Bose,Jun Kameda,Jim Mori,Emily E. Brodsky,Nobuhisa Eguchi,Sean Toczko,Expedition,T Scientists +16 more
TL;DR: Observations from boreholes drilled by the Integrated Ocean Drilling Program Expedition 343 and 343T show a single major plate-boundary fault accommodated the large slip of the Tohoku-Oki earthquake rupture, as well as nearly all the cumulative interplate motion at the drill site.
Book ChapterDOI
The habitat of fault-generated pseudotachylyte : Presence vs. absence of friction-melt
Richard H. Sibson,Virginia Toy +1 more
TL;DR: Fault-hosted pseudotachylyte is rare and largely restricted to crystalline host rocks as mentioned in this paper, and their apparent scarcity raises the question as to whether pseudotsycholyte is rarely generated (perhaps because of dynamic lowering of shear resistance).
Drilling reveals fluid control on architecture and rupture of the Alpine Fault, New Zealand

Menzies,Timothy A. Little,M. A. Hasting,G. P. De Pascale,Robert Langridge,Hannah Scott,Z. Reid Lindroos,B. Fleming,Achim J Kopf +19 more
TL;DR: In this paper, the first two boreholes (Deep Fault Drilling Project DFDP-1) of the Alpine fault were used to reveal a >50m-thick alteration zone formed by fluid-rock interaction and mineralization above background regional levels.
