The structure and emplacement of cinder cone fields. An overview by Richard Fletcher
Study objectives • Identifying differences in emplacement and structures between flank cinder cones and flat lying volcanic field cones. • Flank cones studied around: Mauna Kea. Hawaii; Mt. Etna, Italy; Kilimanjaro, Tanzania. • Platform cones studied around: San Francisco Mtn., Arizona; Paricutin region, Mexico; Nunivak Island, Alaska.
Implications • Lunar cones have smaller rim heights and larger basal diameters due to less gravity and atmospheric drag. • Morphometeric analysis suggests the shape and size is a function of age and erosive processes. • Younger cones indicate active volcanism methods (conduits and dikes).
