Morphometric evolution of compositevolcanoes

basalts (Fuji, Fuego, Izalco); thus petrology may be less important in determining the morphology of compositecones than eruption style, as is true for shieldvolcanoes (Wood, 1977... cones were synthesized with newly determined meas...

The hypothesis that shields represent cindercones that have continued on long eruptive lives is not dissimilar from interpretations developed by McBirney and White (1982) regarding the formation of large silicic centers such as compo...

Distribution, Morphology, and Size Frequency of CinderCones on Mauna Kea Volcano, Hawaii

Abstract More than 300 cindercones on the upper slopes of Mauna Kea volcano reach concentrations of 8/km2 along three principal rift zones where porous low-density tephra may constitute as much as 50 percent by volume of late alkalic...

Contrasting volcanism in the Michoacan-Guanajuato Volcanic Field, central Mexico: Shieldvolcanoes vs. cindercones

Abstract The Michoacan-Guanajuato Volcanic field (40 000 km2) of the western Mexican Volcanic Belt contains both small- and medium-sized volcanoes, but lacks large compositevolcanoes. The small-sized volcanoes include 900 cinder cone...

Old cindercone or young compositevolcano?: The nature of Cerro Negro, Nicaragua

Determining whether a volcano is a cindercone or a compositevolcano is important because its classification categorizes the magmatic system and associated volcanic hazards. The criteria of age and size of the volcano that are usual...

Relationships of cindercones to stratovolcanoes in the Cascadia subduction zone

Despite this fundamental tenet of igneous petrology, very few studies have quantified in detail the spatial distribution of mafic centers, like cindercones, and larger silicic centers, like stratovolcanoes. Here, I explore these rela...
