Petrology of the Luingo caldera (SE margin of the Puna plateau): A middle Miocene window of the arc-back arc configuration
(Elsevier Science, 2011-03)
We describe the petrographic characteristics, whole-rock geochemistry and mineral chemistry of rocks from the Pucarilla-Cerro Tipillas Volcanic Complex with emphasis on the rocks belonging to the middle Miocene Luingo ...
Diversity of volcanism and evidence of discrete eruption centres in the Miocene Andes of Central Chile
(2023)
The geology of the Farellones region in the Andean Cordillera of central Chile, comprise a thick sequence of volcanic and volcaniclastic Miocene rocks. The occurrence of discrete eruption centres within this sequence, ...
The Granada ignimbrite: A compound pyroclastic unit and its relationship with Upper Miocene caldera volcanism in the northern Puna
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The Granada ignimbrite, an Upper Miocene volcanic unit from the northern Puna, previously has been interpreted as an extensive ignimbrite (>2300 km(2)) associated with eruptions from the Vilama caldera (trap-door event). ...
Abanico East Formation: petrology and geochemistry of volcanic rocks behind the Cenozoic arc front in the Andean Cordillera, central Chile (33°50'S)
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2006)
Geochemical constraints on the relationship between the Miocene–Pliocene volcanism and tectonics in the Palaoco and Fortunoso volcanic fields, Mendoza Region, Argentina: New insights from 40Ar/39Ar dating, Sr–Nd–Pb isotopes and trace elements
(Elsevier Science, 2013-10-01)
New 40Ar/39Ar analyses constrain the formation of the volcanic succession of Sierra de Palaoco in the presentback-arc of the Andean Southern Volcanic Zone (SVZ), near 36°S, to the Late Miocene and assigns them to theHuincán ...
Fossilised geothermal surface features of the Whitianga Volcanic Centre (Miocene), Coromandel Volcanic Zone, New Zealand: Controls and characteristics
(Elsevier Science, 2019-09)
The Late Miocene Whitianga Volcanic Centre of the Coromandel Volcanic Zone, North Island, New Zealand, is host to 18 known, siliceous and intensely silicified deposits including: silicified volcanics; sediments of inferred ...
Petrogenesis of Miocene volcanic arc rocks over the Chilean-Pampean flat-slab segment of the Central Andes constrained by mineral chemistry
(Universidad de Barcelona, 2014-06)
Miocene arc volcanism is manifested widely in the Valle del Cura-El Indio belt region (29°30´–30° South latitude), in the southern Central Andes of Argentina and Chile. The magmas that fed this volcanism are well represented ...
