This volume presents a unique compendium of papers assessing the
effects of volcanism on lakes, as recorded by the volcaniclastic
sediments deposited within them. The unifying theme is that the
effects of volcanism on lacustrine sedimentation are diverse and
distinctive, and that volcaniclastic lacustrine sediments hold the
key to understanding a range of processes and events that cannot be
readily addressed by the study of any non-volcanic lakes. Thirteen papers, with authors from nine countries, examine both
modern and ancient eruption-affected lacustrine deposits. Volcanic
eruptions affect lakes and their deposits in many ways, and these
papers evaluate processes and products of volcanic eruptions within
lakes, of tectonically impounded lakes strongly influenced by
volcanism, of eruption-impounded lakes and of general factors
controlling sedimentation of vitric ash and pumice.
Tephrastratigraphic studies also take advantage of the exceptional
preservation of thin laminae in quiet lakes to precisely date
episodes in the evolution of long-lived lakes and their catchment
areas, and to understand how volcanism affects normal lacustrine
processes. The volume as a whole is an unparalleled source of information
on all aspects of the physical sedimentary results of volcanism in
lacustrine settings, and serves as a complement to other studies
concerned primarily with thermal and geochemical characteristics of
lakes within volcanic craters. If you are a member of the International Association of Sedimentologists, for purchasing details, please see: http: //www.iasnet.org/publications/details.asp?code=SP30
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 140.Subaqueous explosive eruptions are common, and in earth's early history were ubiquitous. Although they are unlike eruptions we find on land, they operate with the same fundamental processes. Deep-sea eruptions modify important seafloor hydrothermal systems and their coupled habitats for extremophile organisms, and large eruptions on the continental shelf presumably have as yet unknown effects on a wide range of marine organisms. Shallow eruptions that can affect shipping lanes and threaten coastal environments, either directly or by generation of tsunami, also appear to produce deposits and conditions closely linked with formation of significant chunks of the world's mineral resources.
