Insight into volcanic garnet: origin and significance of garnet as exemplified by a detailed petro-mineralogical study of the Breziny andesite (Central Slovakia Volcanic Field, Western Carpathians, Central Europe)

Autor: Jacky Bouloton

Publikováno v: Volcanica, Vol 4, Iss 2, Pp 149-187 (2021)

Almandine-rich garnets from a Neogene andesite of Slovakia can be divided into two main types. Garnet megacrysts are magmatic and form a chemically homogeneous group that contains, on average, about 5 wt% CaO and 4.5 wt% MgO as petrogenetically signi

International audience; A dyke swarm composed of hypabyssal rocks of intermediate composition cross-cuts Variscan granites and Palaeozoic metasedimentary country-rocks of the Jebilet range. Based on K-Ar isotope dating on kaersutite phenocrysts, thes

Origine du grenat dans le microgranite du Montasset (massif du Velay, France)

Autor: Jean-Marc Montel, Cyrille Pellier, Jacky Bouloton

Publikováno v: Comptes Rendus de l'Académie des Sciences - Series IIA - Earth and Planetary Science. 330:241-244

Garnets from the Montasset microgranite (Velay, France) are the most magnesian garnets (up to 38.5 mol % pyrope) ever described in acidic rocks. Textural relations and chemical zoning profiles indicate that they grew with rising temperature in equili

Mise en évidence de cordiérite héritée des terrains traversés dans le pluton granitique des Oulad Ouaslam (Jebilet, Maroc)

Autor: Jacky Bouloton

Publikováno v: Canadian Journal of Earth Sciences. 29:658-668

Cordierite, a quite common mineral in granitic rocks, originates from various processes; many types of crystals can be found in a given massif. The high-level Oulad Ouaslam pluton, in Morocco, displays cordierites of three different origins. Primary

A garnet-spinel metaperidotite body has been found in the leptyno-amphibolitic complex of the central pan of the Maures Massif (Hercynian Belt, south eastern France). Based on bulk rock and mineral chemistry, a mantle tectonite origin can be ruled ou
