Intrusive hyaloclastite and peperitic breccias associated to sill and cryptodome emplacement on an Early Paleocene polymagmatic compound cone-dome volcanic complex from El Guanaco mine, Northern Chile
(Elsevier Science, 2018-04)
This work explores the textural characteristics, morphology and facies architecture of well-preserved Paleocene hyaloclastic and peperitic breccias associated with subvolcanic intrusions at El Guanaco gold mine (Northern ...
Feições de interação vulcano-sedimentares : seu uso como indicadores de contemporaneidade no magmatismo Rodeio Velho (meso-ordoviciano) e no vulcanismo Serra Geral (cretáceo inferior)
(Universidade do Vale do Rio dos Sinos, 2006-01-13)
Volcanic-sedimentary interaction features were studied in association with two volcanic events: Rodeio Velho Magmatism (470 Ma), associated to Santa Bárbara and Guaritas allogroups (Camaquã Basin), at the localities of ...

New insights on the occurrence of peperites and sedimentary deposits within the silicic volcanic sequences of the Parana Magmatic Province, Brazil
(Copernicus Gesellschaft Mbh, 2014-01-01)
The PMP (Parana Magmatic Province) is characterized by lava flows of the Early Cretaceous Serra Geral Formation which covers about 75% of the Parana Basin (southern and southeastern Brazil), composed of a thick (up to 1600 ...
Neoproterozoic subaqueous extrusive-intrusive rocks in the Playa Hermosa Formation in Uruguay: Regional and stratigraphic significance
(Elsevier Science, 2009-08)
Volcanic rocks in southern Uruguay are linked to an extensional tectonic regime related to the post-collisional Brasiliano-Pan African orogenic cycle. The ca 580 Ma magmatic event is recorded in the Playa Hermosa Formation. ...
