Transformation of Refractory Oceanic Lithospheric Mantle by Reactive Melt Infiltration: An Experimental Study on the Roles of Temperature, Melt Volume and Ascent Velocity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Reactive melt infiltration critically modifies the physical and chemical properties of the oceanic lithospheric mantle (OLM). This process, involving melt‐rock reactions and in situ crystallization, exhibits substantial spatial and temporal variability driven by melt volume and ascent velocity.

A crystal chemical re-evaluation of amphibole/melt and amphibole/clinopyroxene D-Ti values in petrogenetic studies

, 2000
Constraints on the calculation and use of mineral/melt and two-mineral partition coefficients for Ti (D-Ti) have been derived from current knowledge of the distinct crystal-chemical mechanisms for the incorporation of Ti4+ in the amphibole structure as ...

Greek Commodities in Phoenicia: An Interdisciplinary Study of Imported Amphorae From Tell el‐Burak (Lebanon)

Archaeometry, Volume 68, Issue 3, Page 395-408, June 2026.
ABSTRACT This paper examines transport amphorae of Greek/Aegean types from the 7th–4th c. BCE imported to the Phoenician coastal settlement of Tell el‐Burak, Lebanon. We present a selection of 58 pieces analyzed by typological, chemical (NAA), and petrographic approaches.

Tracking Dehydration Reactions and Fossil Fluid Flux in Shear Zones Using Garnet Microstructures

Journal of Metamorphic Geology, Volume 44, Issue 5, Page 394-414, June 2026.
ABSTRACT Shear zones act as preferential fluid pathways during prograde and retrograde stages of metamorphism. Nonetheless, we still have limited knowledge of the drainage and permeability of natural settings. The preserved signature of fluid in exhumed rocks provides insights into fluid flow during burial and exhumation.

Clinopyroxene precursors to amphibole sponge in arc crust

, 2014
The formation of amphibole cumulates beneath arc volcanoes is a key control on magma geochemistry, and generates a hydrous lower crust. Despite being widely inferred from trace element geochemistry as a major lower crustal phase, amphibole is neither ...

Compositional Zoning in Amphibole from Amphibole Bearing Parageneses of West Psunj (Croatia): Evidence for Progressive Metamorphism?

, 1997
Amphibole bearing parageneses from the western part of Mt. Psunj (Croatia) record evidence of prograding metamorphism. Optical and microprobe analyses, together with thermobarometric evaluations on amphibole bearing parageneses, show a zonation with Si ...
