It may be Friday, but it's never too late for #ThinSectionThursday 😁 🤡 Here's a rock (from @geologymull) newly photo'd yesterday: a lovely fresh olivine dolerite from the very-rarely-visited Stac Mhic Mhurchaidh, an uninhabited rock west of Iona. The violet colour of the clinopyroxene crystals "bespeaks titanium" as the early C20th geological survey reports elegantly used to say. 🤓 😊 Field of view about 3.5mm wide. More image info in Alt-txt.

Hellenic Survey of Geology and Mineral Exploration (HSGME): The library of the H.S.G.M.E. is being digitized. “[Researchers] have access to more than 88,000 titles — including 12,000 unpublished scientific and technical reports and studies, around 4,500 maps (dating back to 1891), and 40,000 issues of Greek and international scientific journals. Additionally, 277 books are classified as ‘Rare […]

Du nouveau chez Minetosh online (https://www.minetoshsoft.com):
La troisième partie d'« AmphiCalc-1 » pour le calcul et la classification des amphiboles est désormais en ligne : « Amp15KX » pour le calcul des compositions d'amphiboles sur la base de 15 cations sans potassium et calcium uniquement en position B.

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 third part of “AmphiCalc-1” for calculating and classifying amphiboles is now online: “Amp15KX” for calculating amphibole compositions based on 15 cations without potassium; calcium only on position B.

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.

Der dritte Teil von "AmphiCalc-1" zur Berechnung und Klassifizierung von Amphibolen ist nun online: "Amp15KX" zur Berechnung von Amphibol-Zusammensetzungen auf der Grundlage von 15 Kationen ohne Kalium, mit Calcium nur auf Position B.

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.
