Ignimbrites to batholiths

, 2016
Ignimbrites sample large magma reservoirs in the Earth’s upper crust, sometimes digging deep enough to link the volcanic realm with the plutonic world.

The Arequita formation (Lower Cretaceous): petrographic features of the volcanic facies in the Laguna Merín Basin, East Uruguay

Latin American Journal of Sedimentology and Basin Analysis, 2009
The southeastern border of the Laguna Merín Basin (Rocha Department, East Uruguay) consists of Mesozoic volcanic deposits of the Puerto Gómez and Arequita formations, overlain by a sedimentary cover of Cenozoic and recent deposits.

Geochemical correlation of three large-volume ignimbrites from the Yellowstone hotspot track, Idaho, USA

, 2011
Three voluminous rhyolitic ignimbrites have been identified along the southern margin of the central Snake River Plain. As a result of wide-scale correlations, new volume estimates can be made for these deposits: ~350 km³ for the ...

Phonolitic origin of Roque-Nublo ignimbrites of Gran-Canaria (Canary-Islands, Spain) from clinopyroxene melt inclusion studies

, 1993
The Roque Nublo non-welded ignimbrites - which are Pliocene in age (5-3.5 Ma.) - are characteristic deposits of the second magmatic cycle on Gran Canaria.

Ignimbrites of the Pliocene Bagaces Formation near Cañas (Guanacaste, Costa Rica)

, 2007
By this study, four units within the so far mostly undivided Bagaces Formation - a major ignimbrite unit of the Plio- to Pleistocene magmatic succession in northern Costa Rica - were identified and their ignimbrite sequences stratigraphically ...

U-Pb dating of magmatic and xenocryst zircons from Mangakino ignimbrites and their correlation with detrital zircons from the Torlesse metasediments, Taupo Volcanic Zone, New Zealand

, 2009
Mangakino ignimbrites are a sequence of voluminous eruptive units in the rhyolitic Mangakino Volcanic Centre (MVC) caldera complex, Taupo Volcanic Zone, New Zealand. U-Pb dating of 113 zircons extracted from four Mangakino ignimbrites revealsmagmatic and

Calibrating the pTRM and charcoal reflectance (Ro%) methods to determine the emplacement temperature of ignimbrites: Fogo A sequence, São Miguel, Azores, Portugal, as a case study

, 2015
The emplacement temperatures of three ignimbrites belonging to the 4.6-ka Fogo A plinian eruption sequence in São Miguel Island (Azores, Portugal) were determined using partial thermal remanent magnetization (pTRM) of lithic clasts and reflectance (Ro%)
