Originally from Brazil, Bruna is a research fellow at the University of Padua in Italy. Her research involves the study of anatexis and fluid regime of the deep portions of the continental crust using melt and fluid inclusions. Find out more about her work here.
Geologists working very hard as we do. One of the many reasons I love the Alps is because one can transect the entire crust from fiamme-bearing ignimbrites at Crevacuore to … … the mantle as seen here near Balmuccia where fresh peridotite is intruded by peroxenite dikes. The Balmuccia Peridotite is located up the Val […]
This eclogitic blueschist was collected from Chamois, Italy in the Zermatt-Saas ophiolite. At this locality, smooshed pillow basalts are clearly seen at the top of the ophiolite section although in most areas the primary magmatic textures have been obliterated by high pressure metamorphism. This sample contains glaucophane, jadite/omphacite, lawsonite (pseudomorphs), and other secondary minerals. The […]
This month I was lucky enough to again participate in the “Anatomy of an Orogeny” field course in the Alps with the University of St Andrews. Last year I had four posts outlining our transect from Milan, Italy to Berne, Switerzland (clockwise from upper left: Sesia-Lanzo, Ivrea Verbano, Flysch and Molasse, Helvetic Nappes). This year we had great […]
Flysch and Molasse are terms that describe different sets of sedimentary facies associated with orogenic belts. Molasse is defined as terrestrial and shallow marine deposits formed nearest the rising mountain front. It consists of various interbedded rock types including conglomerates, sandstones, and shales. The flysch on the other hand is made up of deep marine […]
