This book was released on 2021-06-09 with total page 802 pages. Available in PDF, EPUB and Kindle. Book excerpt: This memoir is the first to review all of Antarctica’s volcanism between 200 million years ago and the Present. The region is still volcanically active. The volume is an amalgamation of in-depth syntheses, which are presented within distinctly different tectonic settings. Each is described in terms of (1) the volcanology and eruptive palaeoenvironments; (2) petrology and origin of magma; and (3) active volcanism, including tephrochronology. Important volcanic episodes include: astonishingly voluminous mafic and felsic volcanic deposits associated with the Jurassic break-up of Gondwana; the construction and progressive demise of a major Jurassic to Present continental arc, including back-arc alkaline basalts and volcanism in a young ensialic marginal basin; Miocene to Pleistocene mafic volcanism associated with post-subduction slab-window formation; numerous Neogene alkaline volcanoes, including the massive Erebus volcano and its persistent phonolitic lava lake, that are widely distributed within and adjacent to one of the world’s major zones of lithospheric extension (the West Antarctic Rift System); and very young ultrapotassic volcanism erupted subglacially and forming a world-wide type example (Gaussberg).

Book excerpt: Understanding crustal modification of magmas in volcanic arcs is a fundamental problem of igneous petrology and geochemistry. This dissertation examines the role of crustal processes including crustal assimilation, magma mixing, magma differentiation, and volatile transport in generating erupted magmas from four volcanic systems in the Kamchatka Volcanic arc: Bezymianny, Klyuchevskoy, Shiveluch, and Karymsky. High-precision Pb isotope data from the Central Kamchatka Depression (CKD) record lower crustal assimilation and magma mixing of less radiogenic crust and melt into the magmas of Bezymianny volcano. Unradiogenic Pb isotope compositions in CKD magmas suggest that lower crustal assimilation occurs to a larger extent beneath the CKD than in other segments of the Kamchatka arc. Klyuchevskoy compositional variations support this argument and also show that the degree of assimilation beneath an individual volcanic center may vary on a decadal timescale. Documented lower crustal assimilation by magmas beneath the CKD modifies uranium-series isotope disequilibrium compositions of CKD magmas. U-series isotopes are the only radioactive isotope system with half-lives useful for understanding the timing of volcanic processes. Constraining the affect of crustal processes that alter U-series compositions is essential to interpret isotope signatures. Chapter 2 of this dissertation shows that lower crustal assimilation and fractional crystallization of high-pressure clinopyroxene modifies U-excess to form Th-xcess compositions. Global documentation of Th-excess reveals a correlation of Th-excess disequilibria with hot lower crustal geologic settings. Th-excess may therefore be an important chemical tracer of lower crustal assimilation. Shallow magma storage and degassing is investigated using (210Pb)/(226Ra) compositions at periodically erupting volcanoes with well-constrained degassing and eruptive histories. Current models that predict (210Pb)/(226Ra) as a function of gas loss do not accurately predict the observed compositions of erupted products in Kamchatka. This paradox has important implications for the timescales of magma storage and degassing in the crust. Chapter 4 of this work is a detailed isotopic study of environmental uranium contamination from an abandoned open-pit mine. Uranium isotope data fingerprint alteration of the mine source and transport of uranium from the mine to sediment in Red Rock Creek on National Forest Service recreational land.

This book was released on 2013 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mixing, crystallization and degassing commonly affect magmas during storage, ascent and eruption from volcanoes. As these interactions cannot be observed directly, they must be characterized using chemical signatures of volcanic eruptive products. In this dissertation, geochemical tracers of magma mixing, crystallization and degassing were employed to investigate the magmatic systems of Kasatochi Island volcano, central Aleutian Islands, and Bezymianny Volcano, Kamchatka, Russia, in three studies. The purpose of the first study was to characterize eruptive products from the 2008 eruption of Kasatochi Island volcano. This eruption produced pumiceous, medium-K andesite, as well as denser, medium-K basaltic andesite, with variable bulk compositions (~52-56 wt. %SiO2 for the basaltic andesite, ~58-62 wt. % SiO2 for the andesite). The basaltic andesite and andesite must have resided in separate storage areas until just prior to eruption, with mixing between these magmas limited to just prior to eruption. The second study focused on basaltic andesite from the 2008 Kasatochi eruption, which contains two plagioclase phenocryst populations and anomalously calcic plagioclase microlites. Compositional heterogeneity in the basaltic andesite resulted from pre-eruptive mixing between mafic and silicic compositional end members. As the calcic plagioclase phenocrysts and microlites are out of equilibrium with groundmass glass, these phenocrysts and microlites likely crystallized mostly in the hotter (900-1000 °C) mafic mixing end member, while more sodic phenocrysts crystallized in the cooler (800-950 °C) felsic end member. Mixing between the silicic and mafic end members imposed an undercooling on the mafic magma, triggering plagioclase microlite nucleation in these more calcic liquids. The purpose of the final study was to investigate magmatic evolution of Bezymianny Volcano in Kamchatka, Russia through analyses of major, trace and volatile element compositions of melt inclusions. Inclusions dominantly record pressures of inclusion entrapment
