As part of the 2007 Marnaut cruise in Sea Marmara, an investigation pore fluid chemistry sites along Main Marmara Fault zone was conducted. The goal to define spatial relationship between active faults and outlets determine sources evolution fluids. Sites included basin bounding transtensional strike‐slip cutting through topographic highs. fluids are dominated by simple mixing bottom water with a brackish, low‐density Pleistocene Lake end‐member that is advecting buoyantly and/or diffusing...
Slow slip events (SSEs) accommodate a significant proportion of tectonic plate motion at subduction zones, yet little is known about the faults that actually host them. The shallow depth (<2 km) well-documented SSEs Hikurangi zone offshore New Zealand offers unique opportunity to link geophysical imaging with direct access incoming material represents megathrust fault rocks hosting slow slip. Two recent International Ocean Discovery Program Expeditions sampled this before it entrained...
Abstract The Corinth rift (Greece) is one of the world's most active rifts. early Plio‐Pleistocene preserved in northern Peloponnese peninsula, south rift. Although chronostratigraphic resolution limited, new structural, stratigraphic and sedimentological data for an area >400 km 2 record evolution three phases separated by distinct episodes extension rate acceleration northward fault migration associated with major erosion. Minimum total N–S estimated at 6.4–7.7 km. earliest...
Plate-boundary fault rupture during the 2004 Sumatra-Andaman subduction earthquake extended closer to trench than expected, increasing and tsunami size. International Ocean Discovery Program Expedition 362 sampled incoming sediments offshore northern Sumatra, revealing recent release of fresh water within deep sediments. Thermal modeling links this freshening amorphous silica dehydration driven by rapid burial-induced temperature increases in past 9 million years. Complete silicates is...
A holistic view of the Bengal–Nicobar Fan system requires sampling full sedimentary section Nicobar Fan, which was achieved for first time by International Ocean Discovery Program (IODP) Expedition 362 west North Sumatra. We identified a distinct rise in sediment accumulation rate (SAR) beginning ∼9.5 Ma and reaching 250–350 m/Myr 9.5–2 interval, equal or far exceed rates on Bengal at similar latitudes. This marked SAR constant Himalayan-derived provenance necessitates major restructuring...
In this study, we used porosity to assess the compaction state of Nankai accretionary wedge sediments and any implications for stress pore pressure. However, hydrous minerals affect measurements, accounting them is essential toward defining interstitial truly representative state. The water content was measured in core samples estimated from logging data using a resistivity model shale. We cation exchange capacity correct amount bound clay estimates surface conductivity minerals. results...
Fluids venting from the submarine portion of Marmara Main Fault (part North Anatolian system, Turkey) were sampled in Ti bottles deployed by submersible. The fluids consist mixtures fault derived gases, related cold seep fluids, and ambient seawater; these components can readily be distinguished using isotopes He He/Ne ratios. 3He/4He ratios range between 0.03±0.1 4.9±0.4 Ra, indicating that both crustal mantle sources helium are fault. dominant gas all samples analyzed is methane with...
Abstract Hosting both tsunami earthquakes and slow slip events at shallow depth, the northern Hikurangi margin has motivated strong research efforts over last two decades to better understand relation between fluid pressure fault mechanical behavior. Recently, IODP Expeditions 372 375 drilled, cored, logged basin entering this subduction zone providing a unique opportunity characterize initial hydrogeological petrophysical properties that drive seismic hazards along margin. We inventory...
Abstract Fluid pressure variations in time are thought to influence fault slip. Solitary (self‐similar) waves one process by which a step increase may be transmitted along zone. Hypothetically, solitary wave propagation could coupled with silent Here we present two‐dimensional model of low‐angle fault, scaled case example from Nankai accretionary wedge, and examine sensitivity décollement permeability. This takes into account the effect leakage out zone pore diffusion surrounding medium. We...
