Tectonics, Volume 45, Issue 4, April 2026.Abstract Our understanding of subduction initiation remains limited by the difficulty of making direct observations of geologically recent examples. In the geologic record, supra‐subduction zone ophiolites are often interpreted to record syn‐initiation slab rollback and upper plate extension. Unfortunately, many ophiolites are decoupled from records of

Modeling of Physical–Chemical and Thermomechanical Properties of Glasses From Recycled Waste
International Journal of Applied Glass Science, Volume 17, Issue 2, April 2026.ABSTRACT This research focuses on understanding the high‐temperature phase evolution occurring during the vitrification of heterogeneous construction and demolition wastes (CDWs). The aim of this project is to transform this widely distributed and mostly unused waste stream into a homogeneous, engineered, glass‐based material with predictable ...

Coesite Discovery in Eclogites Confirms UHP Metamorphism in the Orlica‐Śnieżnik Dome (SW Poland)
Journal of Metamorphic Geology, Volume 44, Issue 3, Page 200-225, April 2026.ABSTRACT Eclogite lenses are exposed within the orthogneiss‐dominated core of the Orlica‐Śnieżnik Dome in the Sudetes, which forms the northeastern margin of the Bohemian Massif (Variscan Belt of Central Europe). The presence of coesite inclusions in garnet and omphacite confirms that these eclogites underwent ultrahigh‐pressure metamorphism.

Geochemistry and petrology of primitive achondrite meteorites LEW 88280, MAC 88177, ALHA 81187, EET 84302, and LEW 88663 [PDF]
Primitive achondrites are meteorites that have mineral and bulk chemical compositions similar to the most primitive meteorites (chondrites) but have textures similar to more evolved meteorites (achondrites).

Petrography and mineral chemistry of Northeast Africa 053—A remnant of Martian crystal mush
Meteoritics &Planetary Science, Volume 61, Issue 4, Page 621-643, April 2026.Abstract In Earth's igneous systems, crystal mushes, crystal‐rich frameworks permeated by silicate melt, represent a common and fundamental stage in the evolution of magma bodies. However, whether crystal mushes occur within Martian igneous systems and play a comparable role is unknown. Here, we present a comprehensive petrography and mineral chemistry

The 1723 AD violent Strombolian and phreatomagatic eruption at Irazu volcano (Costa Rica) [PDF]
, 2013 The largest of the recorded historic eruptions at Irazú volcano began on February 16, 1723 and lasted until at least December 11. We here critically examine deposits of this eruption exposed on the summit of Irazú. Our reconstruction of the eruption is

An Evaluation of Garnet – Clinopyroxene Geothermometer
The garnet-clinopyroxene pair commonly found in upper amphibolite, granulite, and eclogite facies assemblage, as well as in garnet peridotites serves as a basic tool to estimate the equilibrium temperature for these metamorphic rocks. Several empirical and experimental calibrations for garnet-clinopyroxene thermometers have been proposed in the last ...
