Повний текст джерелаCaldera-forming eruptions are dramatic and destructive natural phenomena, causing severe and sustained consequences to society. This dissertation presents new geochemical and geochronologic data for caldera-forming tuffs and pre- and post-caldera rhyolites of the two youngest caldera complexes in the Snake River Plain (SRP) in the western USA: Heise (6.6-4.5 Ma) and Yellowstone (2.1-0.6 Ma). Caldera complex evolution at Heise and Yellowstone can be described by formation of 3-4 spatially overlapping "nested" calderas, successive collapse of intracaldera fill, and development of a large hydrothermal system. Comparison between Heise and Yellowstone reveals that late-stage rhyolite eruptions have drastic depletions in 18 O that require remelting of large volumes (1,000's of km 3 ) of hydrothermally altered rock. Archean xenoliths and Phanerozoic rocks of the crustal basement beneath the SRP province are not depleted in 18 O and therefore cannot be a source of these rhyolites. Isotopic mixing models indicate that early large-volume rhyolites are produced by melting and hybridization of the crust by mantle-derived basalt, and late-stage rhyolites tap hydrothermally altered portions of intracaldera rocks from previous eruptions. Caldera-forming eruptions at Heise culminated 4.45 Ma with eruption of the 1,800 km 3 Kilgore Tuff, the most voluminous 18 O-depleted rhyolite in the SRP and worldwide. O, Sr, and Nd isotope geochemistry, zircon ages, mineral and whole-rock geochemistry, and liquidus temperatures for Kilgore Tuff samples erupted >100 km apart are similar and/or overlapping within error, indicating derivation from a remarkably homogeneous low-δ 18 O magma reservoir (δ 18 O=3.4[per thousand]). Caldera-wide batch assembly and homogenization of variably 18 O-depleted melt pockets with diverse zircon populations can explain the Kilgore Tuff's genesis. Central Plateau Member (CPM) rhyolites at Yellowstone have the same timing (∼2 million years after the initiation of volcanism), magnitude of δ 18 O depletion (∼3[per thousand] depleted relative to normal rhyolites), and cumulative eruptive volume (∼4,000-4,500 km 3 ) as the Kilgore Tuff of the Heise volcanic field. Isotopic, age, and geochemical data for CPM rhyolites show that they become progressively more homogeneous and evolved from 260 ka to 75 ka. Whereas the Kilgore Tuff erupted climactically as an explosive caldera-forming tuff, CPM rhyolite eruptions record sequential, predominantly effusive, "snapshots" of magma assembly, homogenization, and differentiation. This dissertation includes co-authored materials both previously published and submitted for publication.

Повний текст джерелаLarge-volume calderas are responsible for producing large deposits of rhyolite and high-silica rhyolite, but the mechanisms by which these deposits are produced are still poorly understood. The Kamchatka Peninsula of Russia contains several large calderas and is one of the most volcanically active areas on Earth. Karymshina Caldera, the largest (25 km x 15 km) caldera in Kamchatka, produced an estimated 800 km 3 of high-silica rhyolitic ignimbrites and post-caldera extrusions, which erupted 1.78 and 0.5-0.8 Ma, respectively. SiO2 content ranges from 66.27-71.89 wt% in the ignimbrites and 70.16-77.70 wt% in the post-caldera extrusions studied. Crystal content is primarily quartz and plagioclase, 0.5-2 mm in size, with other minerals. Values of δ18 O, δD, 87 Sr/86 Sr, and 144 Nd/143 Nd indicate little assimilation of crustal material, in contrast to modeling results. XRF analysis indicates a homogeneous magma. The rhyolite-MELTS program was used to model crystallization of a basaltic source with addition of amphibolite partial melt and hydrothermally-altered silicic rock to reproduce the observed compositions. This thesis contains both previously published and co-authored material.

Повний текст джерелаLa dynamique des recharges magmatiques dans les réservoirs de magma silicique est assez mal comprise. Ceci est un problème important, puisque les recharges magmatiques peuvent entraîner l’accumulation rapide de grands volumes de magma pauvre en cristaux, une configuration susceptible d’évoluer vers une éruption cataclysmique et la formation d’une caldeira. Pour comprendre ce processus, j’ai mené une approche combinant expériences et géochimie, afin d’obtenir une vision intégrée et synthétique du processus de recharges magmatiques. Des expériences analogiques dimensionnées montrent que, pour les systèmes siliciques, des injections de magma moins dense montent dans un réservoir magmatique sans se mélanger de façon significative avec le magma du réservoir, et forment un réservoir zoné. Lorsqu’un niveau saturé en cristaux est présent à la base du réservoir, sa présence n’empêche pas l’ascension des injections. En effet, ces injections moins denses arrachent des cristaux à ce niveau et les entraînent vers le toit du réservoir, où se forme une couche constituée d’un mélange du nouveau magma et de cristaux de la base du réservoir. Ce mécanisme a probablement joué un rôle clé dans la génèse des rhyolites post-caldeira précoces à Yellowstone, les rhyolites d’Upper Basin Member. Dans ces laves, j’observe une coexistence de grands cristaux de plagioclase isolés portant des textures en tamis, et de petits cristaux de plagioclase frais, plus calciques, présents en aggrégats avec des pyroxènes et des oxydes. Cette association inhabituelle suggère qu’un magma silicique plus primitif et plus chaud s’est mélangé à des cristaux d’un réservoir magmatique riche en cristaux peu avant son éruption. Dans ce modèle, les aggrégats ont cristallisé depuis le nouveau magma, et les cristaux à textures en tamis ont été arrachés au réservoir cristallin. Par opposition aux rhyolites d’Upper Basin Member, le
