Amphibole–melt disequilibrium in silicic melt of the Aso-4 caldera-forming eruption at Aso Volcano, SW Japan

open access: yesEarth, Planets and Space, 2018
The most recent and largest caldera-forming eruption occurred at ~ 90 ka at Aso Volcano, SW Japan, and is known as the “Aso-4 eruption.” We performed chemical analyses of amphibole phenocrysts from Aso-4 pyroclasts collected from the initial and largest ...

Application of artificial intelligence in the analysis of asbestos fibers [PDF]

open access: yesFrontiers in Public Health
Automated asbestos fiber detection and identification has been the goal of asbestos microscopists for decades. The advent of inexpensive memory, fast digital processing, machine learning, and microscope automation provide the enabling platform for ...

Comparison of various methodological approaches to model asbestos thresholds for mesothelioma [PDF]

open access: yesFrontiers in Public Health
BackgroundThere is evidence to support several modes of action (MoAs), and particularly non-genotoxic MoAs, for mesothelioma induced by asbestiform elongate mineral particles (EMPs).

Experimental constraints on amphibole stability in primitive alkaline and calc-alkaline magmas [PDF]

open access: yes, 2017
Equilibrium crystallization experiments were carried out on two primitive basaltic rocks (APR16: Na2O+K2O=4.40 wt%; CM42: Na2O+K2O=2.59 wt%) with the aim to investigate the amphibole stability in the differentiation processes at deep crustal level, of

Assessment of asbestos exposure in Kyrgyzstan through analysis of raw and processed materials, air samples and human lung tissue [PDF]

open access: yesScientific Reports
Asbestos still represents a major public health problem on a global scale. In Central Asia chrysotile is still mined and used, claiming that it is safer with respect to amphibole asbestos within certain concentrations.

Investigation of the formation processes in the mafic enclaves of Naqadeh plutonic rocks assemblage by zircon U-Pb dating, Sr-Nd isotopic ratios, and amphibole composition [PDF]

open access: yesپترولوژی, 2021
Naqadeh intrusive pluton is composed of two distinct sections of felsic (40 Ma age) and mafic (99 Ma age) rocks. The granitoid rocks of Naqadeh pluton have different types of mafic enclaves, including mafic microgranular enclaves (MME) and quartz ...

Amp-TB2: An Updated Model for Calcic Amphibole Thermobarometry

open access: yesMinerals, 2021
Amphibole (Amp) plays a crucial role in the study of several earth and planetary processes. One of its most common applications is in thermobarometry, especially for volcanic-magmatic systems.

Compositional Variation of Amphiboles During Magma Mixing: A Case Study of Huangyangshan A-Type Granite in Kalamaili Metallogenic Belt, East Junggar, China

open access: yesFrontiers in Earth Science, 2021
The Huangyangshan A-type granitic pluton, distributed along the thrust fault in the Kalamaili region of East Junggar, Xinjiang, China, consists of alkaline granite containing abundant dioritic enclaves that formed via magma mixing.
