Coupled Fracture Mechanics‐Geochemical Model of Reaction‐Driven Cracking
Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.Abstract Reaction‐driven cracking has been discussed for decades. One mechanism is the extension of a microcrack resulting from precipitation. This mechanism can create porosity, permeability and reactive surface area in low‐permeability rock. We model this problem as a fracture loaded over a fraction of its length by a vein.

Polygenetic ophiolite belt of the California Sierra Nevada: Geochronological and tectonostratigraphic development [PDF]
, 1982 The assumption that ophiolite sequences are generated at essentially one point in geologic time by the process of sea-floor spreading is critical for modern concepts in the tectonics of ophiolites and for topics dealing with their structure and petrology.

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.Abstract As part of a project to assess the risk posed by geomagnetically induced currents to the New Zealand electrical transmission network, long period magnetotelluric (MT) measurements have been made at 62 sites in southern South Island of New Zealand, a region where there was previously a complete absence of MT data.

Mineral chemistry of the ophiolitic peridotites and gabbros from the Serow area: Implications for tectonic setting and locating the Neotethys suture in NW Iran [PDF]
, 2014 The Serow ophiolite in NW Iran, located at the Iran-Turkey border, is composed of mantle sequence peridotites, predominantly lherzolitic-harzburgite with subordinate amounts of lherzolite and dunite, and a crustal sequence made from gabbros, diabases ...

The Role of Co‐Seismic Devolatilization in Driving Aftershock Sequences in Greece
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.Abstract We investigate the role of co‐seismic devolatilization in driving aftershock sequences, focusing on three recent sequences in Greece: Thiva, Damasi, and Florina. We use a numerical model incorporating non‐linear diffusion with a source term that accounts for fluid generation via thermal decomposition of carbonates.

Formation and emplacement of the Josephine ophiolite and the Nevadan orogeny in the Klamath Mountains, California-Oregon: U/Pb zircon and ^(40)Ar/^(39)Ar geochronology [PDF]
, 1994 Cordilleran ophiolites typically occur as basement for accreted terranes. In the Klamath Mountains, ophiolitic terranes were progressively accreted by underthrusting beneath North America. The Josephine ophiolite is the youngest of the Klamath ophiolites

American Journal of Science, 2013 The eastern Mediterranean region within the Tethyan realm shows a high concentration of ophiolites with contrasting times of formation and emplacement along the belt: In the Balkans, the ophiolites formed during the early to medial Jurassic, and were obducted during the late Jurassic, whereas in Turkey and farther east, structurally intact Jurassic ...

Tectonics, Volume 44, Issue 8, August 2025.Abstract The tectonic evolution of the Taiwan orogenic belt from the Mesozoic to the Cenozoic remains unclear because of a lack of deterministic geochronological data for unraveling stratal sequences. The precise timing of the Nanao event is crucial for uncovering this evolution and is the focus of this study.

Origin of plagiogranites in the mawat ophiolite complex,kurdistan region, NE Iraq [PDF]
Kirkuk Journal of Science, 2007 The igneous mass in Mawat Ophiolite Complex (MOC) is built up by various basic and ultrabasic intrusions that are associated with minor acidic, intermediate and basic intrusion.

A Vestige of Earth's Oldest Ophiolite
Science, 2007 A sheeted-dike complex within the ∼3.8-billion-year-old Isua supracrustal belt (ISB) in southwest Greenland provides the oldest evidence of oceanic crustal accretion by spreading. The geochemistry of the dikes and associated pillow lavas demonstrates an intraoceanic island arc and mid-ocean ridge–like setting, and their oxygen isotopes suggest a ...
