Troodos: A Giant Serpentinite Diapir
International Journal of Geosciences, 2011 Troodos is a classical ophiolite complex. It is proposed that the serpentinized harzburgites that now form the top of the mountain and represent the originally lowest part of the ophiolite sequence rose as a diapir. This diapiric rise is caused by the pervasive serpentinization of a suboceanic harzburgite, due to rock-sea water interaction.

Accessory Minerals in New Idria serpentinite
, 2019 Serpentinite is a rock composed almost wholly of serpentine-group minerals and contain accessory minerals that are sensitive to formation chemical condition. In 2017 Patton did a study on accessory minerals of an ophiolite.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract Same‐dip double subduction (SDDS), in which two parallel slabs dip in the same direction, has been linked to accelerated plate motion in both modern and ancient convergent systems, such as the Late Cretaceous Africa–Eurasia system. Yet a systematic framework for quantifying how SDDS alters plate kinematics in a large‐scale spherical geometry ...

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.Abstract Magnesite (MgCO3) is a magnesium (Mg) carbonate mineral that records the aqueous environmental conditions of its formation. On Earth, magnesite forms in metamorphic, diagenetic or pedogenic environments, and distinguishing between these environments is critical for understanding the fluid chemistry during magnesite precipitation. Mg carbonates

Tectonics, Volume 45, Issue 9, September 2026.Abstract We present evidence of a previously unrecognized east‐west‐trending normal fault, named the Parguera Fault, in southwest Puerto Rico. The fault is located at the northwestern edge of seismicity from the southwest Puerto Rico seismic sequence that began in 2019, near the coastal town of La Parguera.

Boron isotopes identify deep-slab serpentinite in the source of Aleutian arc magma
Seafloor lavas of the Western Aleutian arc have isotopically heavy boron (delta B-11 to +13.4%(0)) that is negatively correlated with B content (ppm). Endmember samples are primitive dacites and rhyodacites (delta B-11 > +10%(0), SiO2 = 63%-70%, Mg# > 0 ...

Petrological review of the Ófalu serpentinite, Mecsek Mountains, Hungary [PDF]
, 1979 The Ófalu serpentinite as a 10 m thick sill-like body lies in the metamorphites of the Ófalu Group. It consists of two varieties petrographically: ]. massive serpentinite, 2.

Recycling of heavy noble gases by subduction of serpentinite
, 2019 Isotopic analyses of natural samples suggest that the heavy noble gases (HNG; Ar, Kr, and Xe) in the mantle are dominated by components recycled by subduction (Holland and Ballentine, 2006, Kendrick et al., 2011, Parai and Mukhopadhyay, 2018, Smye et al.,

Austral Ecology, Volume 51, Issue 9, September 2026.ABSTRACT The breeding systems of Lutruwita/Tasmania's threatened Epacris taxa are poorly known. Our main objective was to determine the pollinators of several endemic species and explore for relationships between pollinators, floral morphology, flowering time and habitat. The Epacris have limited variation in floral traits and exhibit generalist floral
