Al-in-amphibole barometry of calcalkaline magma: assessment of active subvolcanic systems.
, 2007 Ca-amphiboles (hornblende-hastingsite-pargasite solution) have been historically tested by many authors in order to discern their physic-chemical stability and the evolution of calcalkaline magmas at subduction-related systems.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract The cratonic lithospheric mantle records complex metasomatic processes and is frequently tapped by alkaline magmatism, offering a unique opportunity to trace the progressive evolution of the mantle. In the present contribution, we investigate a newly identified calc‐alkaline lamprophyre field from the Neoarchean Jonnagiri Schist Belt, Eastern ...

Exposure to amphibole asbestos has been associated with production of autoantibodies in mice and humans, and increases the risk of systemic autoimmune disease. However, epidemiological studies of chrysotile exposure have not indicated a similar induction

Magnetic anisotropy in natural amphibole crystals
, 2015 Anisotropy of magnetic susceptibility (AMS) is often used as a proxy for mineral fabric in deformed rocks. To do so quantitatively, it is necessary to quantify the intrinsic magnetic anisotropy of single crystals of rock-forming minerals.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract We present a comprehensive multidisciplinary investigation of the Healy submarine volcano in the southern Kermadec arc, northeast of New Zealand. We show the first results of sidescan‐sonar data collected at a submarine arc volcano by an Autonomous Underwater Vehicle (AUV).

Kôzulite, an Mn-rich alkali amphibole
Acta Crystallographica Section E, 2010 The crystal structure of kôzulite, an Mn-rich alkali amphibole with the ideal formula NaNa2[Mn42+(Fe3+,Al)]Si8O22(OH)2, trisodium tetramanganese iron/aluminium octasilicate dihydroxide, was refined from a natural specimen with composition (K0 ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract The India–Asia collision continuously loads the Tibetan Plateau (TP), driving its Cenozoic eastward growth. This process has caused extensive crustal deformation and a diverse magmatic response. Here, we report on newly identified 35−6.5 Ma granitoids from Kangding area in southeastern (SE) TP.

Near-solidus evolution of oceanic gabbros: insights from amphibole geochemistry
, 2001 The near-solidus evolution of plutonic rocks formed at slow-spreading ridges is investigated using the major and trace element compositions of amphiboles in a suite of gabbros from the Mid-Atlantic Ridge.
