The research area is located in south-eastern Slovenia and belongs to the eastern extensions of Slovenian Basin adjacent Adriatic Carbonate Platform. studied section 25 m thick consists grey, brownish reddish pelagic limestones calciturbidites, two bentonite layers 110 10 cm thick. Both volcanoclastic horizons consist greenish, fine-grained muddy material. To date, no other bentonites similar a...

The Wunugetushan large porphyry Cu–Mo deposit in NE China is hosted by Mesozoic quartz monzonite and has a Mo-rich core Cu-rich rim space. In this paper, melt inclusions intrusions fluid different-stage veins were studied to explore potential parameters leading decoupling. Melt have rhyolitic compositions of 71.7–85.3 wt.% SiO 2 , 1.9–31.3 ppm Cu 1.7–2.6 Mo. Hydrothermal activity occurred over ...

After 11 5 ka of quiescence (24 5–13 ka), the Nevado de Toluca volcano started a 2500 year period of activity. This period was characterized by a dome destruction event at 13 ka, a small Plinian event at 12 1 ka, and a large Plinian eruption at 10 5 ka. About 10 km of magma was erupted that was homogeneous in composition (63 3–65 7 SiO2 wt % whole-rock) and in mineralogy. Pumice consists of pla...

Abstract Breadcrust bombs are pyroclasts displaying fractured, dense surfaces enveloping expanded interiors, and associated with Vulcanian explosions. We document from the 2008–2009 CE eruption of Chaitén (Chile) that internally as well externally breadcrusted. The cut by intersecting micrometer-to millimeter-thick tuffisites glassy walls, which grade into strongly inflated pumiceous material. ...
