Episodic methane concentrations at seep sites on the upper slope Opouawe Bank, southern Hikurangi Margin, New Zealand [PDF]

open access: yes, 2010
Along many active and some passive margins cold seeps are abundant and play an important role in the mechanisms of methane supply from the subsurface into seawater and atmosphere.

Thermal control of the seismogenic zone of southern central Chile [PDF]

open access: yes, 2011
We developed thermal models for the Chile subduction zone along two profiles at 38.2°S and 42°S within the rupture area of the 1960 M = 9.5 Valdivia earthquake and south of the 2010 M = 8.8 Maule earthquake.

Burial and exhumation in a subduction wedge : mutual constraints from thermo-mechanical modelin and natural P-T-t data (Sch. Lustrés, W. Alps) [PDF]

open access: yes, 2007
The dynamic processes leading to synconvergent exhumation of high-pressure low-temperature (HP-LT) rocks at oceanic accretionary margins, as well as the mechanisms maintaining nearly steady state regime in most accretion prisms, remain poorly understood.

Thermal regime of the Costa Rican convergent margin: 1. Along-strike variations in heat flow from probe measurements and estimated from bottom-simulating reflectors [PDF]

open access: yes, 2013
21 pages, 9 figures, 1 tableThe thermal structure of convergent margins provides information related to the tectonics, geodynamics, metamorphism, and fluid flow of active plate boundaries. We report 176 heat flow measurements made with a violin bow style

Offshore geology of Pakistan and non-living resource prospects [PDF]

open access: yes, 1999
Offshore geology of Pakistan is characterized by active and passive continental margins. These continental margins show very unique features such as an active Makran subduction zone in the west and the Indus delta and a submarine fan in the east.

a geophysical and geological study in the southern Gulf of Mexico and at the frontal Makran Accretionary prism, Pakistan [PDF]

open access: yes, 2009
The major objective of the study is to investigate how near-surface sediment structures and other geological aspects control the nature and occurrence of cold fluid seepage. Mainly high resolution multichannel seismic data and swatch bathymetry data were

Analogue Experiments of Subduction vs. Collision Processes: Insights for the Iranian Tectonics

open access: yes, 2005
We investigate, using laboratory experiments, the behavior of subduction-collision transition. These experiments help understanding of the tectonics at the transition between the Zagros collision ranges and the Makran emerged accretionary prism in south ...

Reconstructing the total shortening history of the NW Himalaya. [PDF]

open access: yes, 2003
The onset of India-Asia contact can be dated with both biostratigraphic analysis of syn-collisional sedimentary successions deposited on each side of the Indus Suture zone, and by radiometric dating of Indian crustal rocks which have undergone subduction

Expedition 362 Preliminary Report: Sumatra Subduction Zone [PDF]

open access: yes, 2017
Drilling the input materials of the north Sumatran subduction zone, part of the 5000 km long Sunda subduction zone system and the origin of the Mw ~9.2 earthquake and tsunami that devastated coastal communities around the Indian Ocean in 2004, was ...
