Du nouveau chez Minetosh online (https://www.minetoshsoft.com):

La quatrième partie d'« AmphiCalc-1 » pour le calcul et la classification des amphiboles est désormais en ligne : « Amp15KC » pour le calcul des compositions d'amphiboles sur la base de 15 cations sans potassium et calcium aussi en position C. Ce calcul est particulièrement adapté aux amphiboles sodiques.

AmphiCalc-1 calcule automatiquement à partir d'analyses par microsonde les oxydes, les cations, la composition chimique, la répartition Fe²⁺ et Fe³⁺, ainsi que d'autres paramètres des amphiboles. Les résultats peuvent être téléchargés sous forme de fichier csv. Les diagrammes suivants pour la classification des amphiboles sont créés automatiquement et peuvent être téléchargés sous forme de fichiers svg : diagramme de Leake, diagramme ACF, diagramme AFM.

News from Minetosh online (https://www.minetoshsoft.com):

The fourth part of “AmphiCalc-1” for calculating and classifying amphiboles is now online: “Amp15KC” for calculating amphibole compositions based on 15 cations without potassium; calcium also on position C. This calculation is particularly suitable for sodium amphiboles.

AmphiCalc-1 automatically calculates the oxides, cations, formula occupancy, Fe²⁺ and Fe³⁺ distribution, and other parameters of amphiboles from microprobe analyses. The results can be downloaded as a csv file. The following diagrams for classifying amphiboles are generated automatically and can be downloaded as svg files: Leake diagram, ACF diagram, AFM diagram.

Neues von Minetosh online (https://www.minetoshsoft.com):

Der vierte Teil von "AmphiCalc-1" zur Berechnung und Klassifizierung von Amphibolen ist nun online: "Amp15KC" zur Berechnung von Amphibol-Zusammensetzungen auf der Grundlage von 15 Kationen ohne Kalium; mit Calcium auch auf Position C. Diese Berechnung ist besonders für Na-Amphibole geeignet.

AmphiCalc-1 berechnet aus Mikrosondenanalysen automatisch die Oxide, die Kationen, die Formelbesetzung, die Fe²⁺- und Fe³⁺-Verteilung, sowie weitere Parameter von Amphibolen. Die Ergebnisse lassen sich als csv-Datei herunterladen. Folgende Diagramme zur Klassifizierung der Amphibole werden automatisch erstellt und können als svg-Dateien heruntergeladen werden: Leake-Diagramm, ACF-Diagramm, AFM-Diagramm.

Pierre Lanari (Univ. Lausanne), a Mineralogical Society of America @mineralsocamerica.bsky.social Distinguished Lecturer, presented advancements in constraining the rates of metamorphic reactions, enabled by clever application of element mapping, diffusion modelling and development of freely available software.

A beautifully illustrated, clearly explained talk!

Biotite replacing garnet, from the Willoughby area of the Vermont Appalachians.

#ThinSectionThursday Fabulous 🪶 feathery🪶 symplectite textures in this Lewisian gneiss from the south slopes of Roneval, South Harris. Pink garnet & green clinopyroxene formed during early, hot, high pressure granulite facies metamorphism have reacted during later decompression/hydration to produce zones of finely intergrown amphibole, plagioclase, and opaque magnetite. View ca 2mm across. Tasty! 😋 🥰

#DogWalkingGeology a superb example of a retrogressive reaction front from this morning's walk with Spud at Uisken. To the top+right is garnet amphibolite preserving clean high temperature (about 650-700 oC) metamorphic minerals. The paler green grey rock at bottom+left has formed by later hydration of the amphibolilte at 350-400 oC. The boundary between fresh high grade rock + completely altered low-grade rock is sharp over a distance of a few cm. #Geology #Metamorphism #Retrogression #Mull

Here's some more kyanite from this morning's wee walk near Uisken in Mull. Nice blue kyanite blades up to 3cm+, with some red stonecrop and lichen keeping them company.

Vote #kyanite! The glorious blue harbinger of metamorphism done right: high pressure, and aluminous chemisty = beauty + lots of geo-information 🤩 🥰 🤓

Here's some Mull kyanite, together with it's pink cousin andalusite, in an outcrop at Ardalanish in Mull - what a rock! 😊 😍
