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.

Amphibole control on copper systematics in arcs: Insights from the analysis of global datasets
Geochimica et Cosmochimica Acta, 2021 Copper, sourced from porphyry deposits formed in arc settings, is a critical resource, and is primarily sourced from magmas. However, the processes that shape the copper contents of arc magmas are up for debate.

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).

Journal of Geophysical Research: Solid Earth, 2021 Amphibole is a common hydrous mineral in mantle rocks. To better understand processes leading to the formation of amphibole‐bearing peridotites and pyroxenites in the lithospheric mantle, we conducted experiments by juxtaposing a lherzolite against ...

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.

Geothermobarometry of Sarmeshk granitoids in the Northwest of Sarduiyeh [PDF]
پترولوژی, 2018 The Sarmeshk granitoid pluton is located in southeast of the Urumieh-Dokhtar magmatic zone in the Kerman province. Based on petrographic studies, the granitoid consist of three rock type of diorite, granodiorite and monzogranite. They are mainly composed

Amphibole: A major carrier of helium isotopes in crustal rocks [PDF]
, 2016 The first evidence for a specific role of amphiboles in He isotope balance of crustal rocks was presented in early contributions by Gerling et al. (1971, 1976).

Crystal-chemistry and short-range order of fluoro-edenite and fluoro-pargasite: a combined x-ray diffraction and ftir spectroscopic approach [PDF]
, 2013 In this study we address the crystal-chemistry of a set of five samples of F-rich amphiboles from the Franklin marble (USA), using a combination of microchemical (EMPA), SREF, and FTIR spectroscopy methods. The EMPA data show that three samples fall into
