Preferred orientation distribution of shock‐induced planar microstructures in quartz and feldspar

Autor: Ludovic Ferrière, Jean-Guillaume Feignon, Christian Koeberl, Gordon R. Osinski, Lidia Pittarello

Publikováno v: Meteoritics & Planetary Science

Shocked quartz and feldspar grains commonly exhibit planar microstructures, such as planar fractures, planar deformation features, and possibly microtwins, which are considered to have formed by shock metamorphism. Their orientation and frequency are

Petrography, geochemistry, and shock metamorphism of the impactites from the Chicxulub impact structure peak ring (Yucatán peninsula, Mexico) recovered by the IODPICDP Expedition 364 drilling

Autor: Feignon, Jean-Guillaume

Von April bis Mai 2016 wurde in der IODP-ICDP-Expedition 364 der innere Ring der Chicxulub-Einschlagstruktur (Halbinsel Yucatán, Mexiko, Durchmesser ca. 200 km; Alter 66.05 Ma) erbohrt und ein durchgehender, 829-m-langer Bohrkern (M0077A) gewonnen.

High CO2 content in magmas of the explosive andesitic Enco eruption of Mocho-Choshuenco volcano (Chile)

Autor: Feignon, Jean-Guillaume, Cluzel, Nicolas, Schiavi, Federica, Moune, Séverine, Roche, Olivier, Clavero, Jorge, Schiano, Pierre, Auxerre, Marion

Publikováno v: Bulletin of Volcanology
Bulletin of Volcanology, 2022, 84 (4), pp.40. ⟨10.1007/s00445-022-01550-y⟩

Mocho-Choshuenco volcano has produced several highly explosive eruptions during its history, which make it one of the most hazardous volcanoes in the southern volcanic zone of Chile, although it is still relatively little studied to date. We present
