Volcanic Processes in the Sedimentary Record: When Volcanoes Meet the Environment
CONTAINS OPEN ACCESS

This book brings together research, review and methodological papers that provide an updated view on the sedimentary record of volcanism, spanning diverse processes and environments. It aims to bridge the gap between volcanological and sedimentological approaches to the investigation of processes governing the generation, dispersion and accumulation of volcaniclastic deposits.

Abstract
Sand and sandstone composition of volcanic origin may be clues to the provenance of the sediments and sedimentary rocks. Volcaniclastic provenance studies contribute significantly to unravelling the generation and provenance of sediment under investigation, which in the Aeolian archipelago comprises preserved units of outcrops dominated by lava flows intercalated with airfall tephras as source rocks. The focus of this paper is the study of the petrographical composition and textures of beach sands, which can then be used as a guide in the interpretation of provenance and origin of beach sand(stone)s rich in volcanic debris transported into deeper water. The composition of Aeolian beach deposits defines a single immature petrofacies with a large amount of unweathered glass and mafic minerals. Panarea island is dominated by dacites and new grain categories have been proposed to differentiate this provenance. Surface processes such as mechanical erosion (mass wasting and surface runoff) produce an overestimation of mafic components compared to the felsic components in the beach sand fraction.
