Genetic types and provenance indication of clastic amphibole in the South Yellow Sea [PDF]
Frontiers in Marine ScienceThe main focus of studying sediment sources in marine areas is to determine the properties of clastic minerals originating from different rivers. Variations in the characteristics of clastic minerals occur due to differences in the types of source rocks ...

Polarons in Rock-Forming Minerals: Physical Implications
Condensed Matter, 2022 The existence of thermally-activated quasiparticles in amphiboles is an important issue, as amphiboles are among the main hydrous complex silicate minerals in the Earth’s lithosphere.

Confronting Solid‐State Shear Bias: Magmatic Fabric Contribution to Crustal Seismic Anisotropy
Geophysical Research Letters, 2023 Seismic anisotropy is controlled by aligned rock‐forming minerals, which most studies attribute to solid‐state shear with less consideration for magmatic fabric in plutonic rocks (rigid‐body rotation of crystals in the presence of melt).

Large Igneous Provinces (LIPs) and Anoxia Events in “The Boring Billion”
Geophysical Monograph Series, Page 449-486., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Experimental investigation of trace element partitioning between amphibole and alkali basaltic melt: towards a more general partitioning model with implications for amphibole fractionation at deep crustal levels [PDF]
, 2023 Time-series experiments were carried out in a piston-cylinder apparatus at 0.8 GPa and 1030–1080 °C using a hydrous K-basalt melt as the starting material to determine the element partition coefficients between amphibole and silicate glass. Major, minor,

Dislocation Creep of Olivine and Amphibole in Amphibole Peridotites from Åheim, Norway
, 2021 Amphibole peridotite samples from Åheim, Norway, were analyzed to understand the deformation mechanism and microstructural evolution of olivine and amphibole through the Scandian Orogeny and subsequent exhumation process. Three Åheim amphibole peridotite

Experimentally determined stability of alkali amphibole in metasomatised dunite at sub-arc pressures [PDF]
, 2015 The phase and melting relationships of olivine mixed with 25 % of hydrous felsic slab melt have been determined in piston-cylinder experiments between 2.5 and 4.5 GPa and 800 to 1,050 °C to constrain metasomatic processes in the mantle wedge above ...
