El Campo Volcánico del Cerro Chivo (CVCC), de edad terciario temprana, expone en la superficie manifestaciones de volcanes basálticos monogenéticos, la mayoría del tipo maar-diatrema. Los rasgos reconocidos incluyen diques; ...
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, ...
Root Zones and Diatremes in the Cerro Chivo Volcanic Field (CCVF), Chubut Province, Argentina
(IUGG, 2019)
The underground portion of a maar volcano is called a diatreme, and the transition from diatreme to underlying feeder dike is the root zone. Very few root zones have been documented on outcrop worldwide. Yet this is where ...
Modern analogues for Miocene to Pleistocene alkali basaltic phreatomagmatic fields in the Pannonian Basin: "Soft-substrate" to "combined" aquifer controlled phreatomagmatism in intraplate volcanic fields
(De Gruyter, 2010-09)
The Pannonian Basin (Central Europe) hosts numerous alkali basaltic volcanic fields in an area similar to 200 000 km2. These volcanic fields were formed in an approximate time span of 8 million years producing smallvolume ...
