Available in PDF, EPUB and Kindle. Book excerpt: Hawaiian Volcanoes, From Source to Surface is the outcome of an AGU Chapman Conference held on the Island of Hawai‘i in August 2012. As such, this monograph contains a diversity of research results that highlight the current understanding of how Hawaiian volcanoes work and point out fundamental questions requiring additional exploration. Volume highlights include: Studies that span a range of depths within Earth, from the deep mantle to the atmosphere Methods that cross the disciplines of geochemistry, geology, and geophysics to address issues of fundamental importance to Hawai‘i’s volcanoes Data for use in comparisons with other volcanoes, which can benefit from, and contribute to, a better understanding of Hawai‘i Discussions of the current issues that need to be addressed for a better understanding of Hawaiian volcanism Hawaiian Volcanoes, From Source to Surface will be a valuable resource not only for researchers studying basaltic volcanism and scientists generally interested in volcanoes, but also students beginning their careers in geosciences. This volume will also be of great interest to igneous petrologists, geochemists, and geophysicists.

Available in PDF, EPUB and Kindle. Book excerpt: Lavas from Kilauea Volcano display rapid geochemical and isotopic variations (e.g., 206Pb/204Pb or Nb/Y ratios) on a time scale of decades to centuries. The wall of Kilauea Caldera at Uwekahuna Bluff exposes a sequence of recent prehistoric, caldera-filling lavas (erupted mostly between AD 900-1400). Here, we present a detailed geochemical study (major element abundances, and Pb, Sr, and Nd isotope ratios) for lavas from the lower portion of the Uwekahuna Bluff section as well as trace element abundances for the entire section. The 206Pb/204Pb ratios of the lavas from the lower Uwekahuna Bluff display small variations that merge with an isotopic excursion towards low 206Pb/204Pb ratios in the lavas from the upper portion of the section. At least four distinct source components within the Hawaiian mantle plume are required to explain the variations in Pb, Sr, and Nd isotope ratios. Two of these components were previously thought to be restricted to the neighboring active volcanoes, Mauna Loa and Loihi Seamount. The occurrence of Mauna Loa- and Loihi-like mantle sources in Kilauea's melting region (in addition to Kilauea's typical mantle source) suggests that (1) the Hawaiian plume contains three large-scale compositional heterogeneities and (2) all three heterogeneities extend into Kilauea's melting region. However, the source region of Kilauea lavas must also be heterogeneous on a small scale to explain the rapid variations in the Pb, Sr, and Nd isotope ratios of the lavas. The fourth component appears to be common to all three of the active Hawaiian volcanoes, and thus, might represent the plume matrix. The Uwekahuna Bluff lavas also reveal a systematic temporal excursion in ratios of highly over moderately incompatible trace elements (e.g., Nb/Y) towards the lowest values yet observed at Kilauea. These low Nb/Y ratios (which correlate with the low 206Pb/204Pb ratios) are thought to result from relatively high degrees of partial melting of the plume matrix. Based on a correlation between high inferred degrees of partial melting and high eruption rates historically at Kilauea, the low Nb/Y ratios of the Uwekahuna Bluff lavas suggest that the eruption rate at Kilauea's summit may have been unusually high in recent prehistoric times.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 92. Mauna Loa is a volcano of superlatives: it is the largest active volcano on Earth and among the most productive. This volume serves to place on record the current state of our knowledge concerning Mauna Loa at the beginning of the Decade Volcano Project. The scope is broad, encompassing the geologic and exploratory history of the volcano, an overview of its submarine geology, its structure, petrologic and geochemical characteristics, and what Mauna Loa has to tell us about the Hawaiian mantle plume; it covers also remote sensing methods and the use of gravity, seismic and deformational studies for eruption monitoring and forecasting, hazards associated with the volcano, and even the importance of a changing volcanic landscape with a wide spectrum of climate zones as an ecological laboratory. We have made a deliberate effort to present a comprehensive spectrum of current Mauna Loa research by building on a December 1993 symposium at the AGU Fall Meeting that considered (1) what is currently known about Mauna Loa, (2) critical problems that need to be addressed, and (3) the technical means to solve these problems, and by soliciting contributions that were not part of the symposium. We encouraged authors to consider how their papers relate to others in the volume through crossreferencing. The intent was that this monograph should be a book about Mauna Loa rather than a collection of disparate papers.
