Postglacial Icelandic shield volcanoes were formed in monogenetic eruptions mainly in the early Holocene epoch. Shield volcanoes vary in their cone morphology and in the areal extent of the associated lava flows. This paper presents the results of a study of 24 olivine tholeiite and 7 picrite basaltic shield volcanoes. For the olivine tholeiitic shields the median slope is 2.7°, the median height 60 m, the median diameter 3.6 km, the median aspect ratio (height against diameter) 0.019, and the… 
The violent Strombolian eruption of 10 ka Pelado shield volcano, Sierra Chichinautzin, Central Mexico
Pelado volcano is a typical example of an andesitic Mexican shield with a summital scoria cone. It erupted ca. 10 ka in the central part of an elevated plateau in what is today the southern part of
Distribution, structure, and formation of Holocene lava shields in Iceland
Abstract Lava shields in Iceland are monogenic shield volcanoes mostly composed of primitive basalts, picrite and olivine tholeiite. The Holocene shields are restricted in space and time: in space
Change of eruptive style during Pliocene deglaciation: from scoria cones to lava shields in southern extra-Andean Patagonia, Argentina
Slab window basalt cycles in extra-Andean Patagonia formed in a main-plateau and a post-plateau stage, during glacial and interglacial events. Here, we provide field, geochemical and geochronological
Volcanism in Iceland in historical time: Volcano types, eruption styles and eruptive history
Abstract The large-scale volcanic lineaments in Iceland are an axial zone, which is delineated by the Reykjanes, West and North Volcanic Zones (RVZ, WVZ, NVZ) and the East Volcanic Zone (EVZ), which
Morphometry of terrestrial shield volcanoes
Abstract Shield volcanoes are described as low-angle edifices built primarily by the accumulation of successive lava flows. This generic view of shield volcano morphology is based on a limited number
Morphology of the 1984 open-channel lava flow at Krafla volcano, northern Iceland
Abstract An open-channel lava flow of olivine tholeiite basalt, 9 km long and 1–2 km wide, formed in a volcanic eruption that took place in the Krafla volcano, Iceland, on the 4–18 September 1984.
The interaction of fissure swarms and monogenetic lava shields in the rift zones of Iceland
Abstract The divergent plate boundaries of Iceland are marked by rift zones that consist of fissure swarms, i.e. areas with a high density of fractures, faults and eruptive fissures, generally
Volcanotectonic Evolution and Characteristic Volcanism of the Neovolcanic Zone of Iceland
The thesis focuses on three aspects of the volcanotectonic activity in the Neovolcanic Zone of Iceland: (1) effects of deglaciation, (2) mechanical interaction between central volcanoes, and (3)
The AD 1250 El Metate shield volcano (Michoacán): Mexico’s most voluminous Holocene eruption and its significance for archaeology and hazards
The Michoacán–Guanajuato Volcanic Field is the largest subduction-related monogenetic volcanic field in the world and includes more than 1000 scoria cones and a few hundred medium-sized volcanoes.
The ∼AD 1250 effusive eruption of El Metate shield volcano (Michoacán, Mexico): magma source, crustal storage, eruptive dynamics, and lava rheology
Medium-sized volcanoes, also known as Mexican shields due to their andesitic composition and slightly higher slope angles in comparison to Icelandic shields, occur across the Trans-Mexican Volcanic


Mechanical aspects of postglacial volcanism and tectonics of the Reykjanes Peninsula, southwest Iceland
Four major NE trending postglacial volcanic and tectonic fissure swarms (volcanic systems) occur on the Reykjanes Peninsula, and the westernmost three are the main subject of this paper. Two main
Size, distribution, and magma output rate for shield volcanoes of the Michoacán-Guanajuato volcanic field, Central Mexico
The Michoacan-Guanajuato Volcanic Field (MGVF), in the west-central Mexican Volcanic Belt (MVB), contains nearly 400 medium-sized volcanoes in addition to 1000 small monogenetic cones. The area is
Development of lava tubes in the light of observations at Mauna Ulu, Kilauea Volcano, Hawaii
During the 1969–1974 Mauna Ulu eruption on Kilauea's upper east rift zone, lava tubes were observed to develop by four principal processes: (1) flat, rooted crusts grew across streams within confined
Small domes on Venus: Probable analogs of Icelandic lava shields
On the basis of observed shapes and volumetric estimates, we interpret small, dome-like features on radar images of Venus to be analogs of Icelandic lava-shield volcanoes. Using morphometric data for
Small volcanic edifices and volcanism in the plains of Venus
The most widespread terrain type on Venus consists of volcanic lowland plains. Several styles of volcanism are represented in the plains. The most extensive volcanic units consist of flood lavas, the
Pahoehoe Flows from the 1969–1971 Mauna Ulu Eruption, Kilauea Volcano, Hawaii
Note: This paper is dedicated to Aaron and Elizabeth Waters on the occasion of Dr. Waters' retirement. Three types of chemically similar pahoehoe flows were observed to form during the 1969–1971
Generation and equilibration of olivine tholeiites in the northern rift zone of Iceland. A petrogenetic study of the Bláfjall table mountain
Abstract The Blafjall table mountain is located in the active northern rift zone of Iceland. It is part of an olivine tholeiite complex, erupted mostly during Weichselian times (75-10 ka). The
Venus volcanism: Classification of volcanic features and structures, associations, and global distribution from Magellan data
A preliminary analysis of a global survey of Magellan data covering over 90% of the surface and designed to document the characteristics, location, and dimensions of all major volcanic features on
Pahoehoe and aa in Hawaii: volumetric flow rate controls the lava structure
The historical records of Kilauea and Mauna Loa volcanoes reveal that the rough-surfaced variety of basalt lava called aa forms when lava flows at a high volumetric rate (>5–10 m3/s), and the
Effect of glacier loading/deloading on volcanism: postglacial volcanic production rate of the Dyngjufjöll area, central Iceland
Tephrochronological dating of postglacial volcanism in the Dyngjufjöll volcanic complex, a major spreading center in the Icelandic Rift Zone, indicates a high production rate in the millennia
