Understanding Eruption Processes and Post-Eruption Geomorphic Evolution of Basaltic Volcanoes

This article summarizes the formation and evolution of basaltic cinder cones such as Red Cone, Black Cone, and Little Cones in S. Nevada, influenced by an arid to semiarid climate. It explores post-eruption geomorphic evolution, including growth, erosion, and the complex histories of these cones, which are developed through explosive processes and lateral expansion. The study emphasizes the significance of pyroclastic mound formation, cone failure, deconstruction, and healing in understanding the landscapes shaped by these volcanic features.
