Book Synopsis The 2 ka Eruption of Misti Volcano, Southern Peru—The Most Recent Plinian Eruption of Arequipa’s Iconic Volcano by : Christopher J. Harpel
Download or read book The 2 ka Eruption of Misti Volcano, Southern Peru—The Most Recent Plinian Eruption of Arequipa’s Iconic Volcano written by Christopher J. Harpel and published by Geological Society of America. This book was released on 2011-11-28 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Misti volcano’s last Plinian eruption, which happened ca. 2 ka, emplaced voluminous tephra-fall, pyroclastic-flow, and lahar deposits. Arequipa, located at the foot of the volcano, has a population of over 800,000 people and growing. Misti will erupt explosively again, and it is important to understand the past Plinian eruption. This Special Paper first provides a detailed description and analysis of the lahar deposits from the 2 ka eruption and the flows that emplaced them. Because Misti is located in an arid region, the authors have also included a detailed discussion of the paleoclimate conditions that provided the water for such voluminous lahars. The authors further delineate the complete eruption sequence for the pyroclastic-flow and tephra-fall deposits, providing a narrative of the eruption progression and dynamics. Finally, the book discusses the 2 ka eruption in the context of hazards from a future Plinian eruption and provides hazards maps for the different phenomena.
Book Synopsis Evolution of Plinian Magmas from Popocatépetl Volcano, México by : Giovanni Sosa Ceballos
Download or read book Evolution of Plinian Magmas from Popocatépetl Volcano, México written by Giovanni Sosa Ceballos and published by . This book was released on 2011 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fractional crystallization, magma mixing, assimilation of continental crust, and how those processes modify volatile budgets, control the evolution of magma. As a consequence, the understanding of these processes, their magnitudes, and timescales is critical for interpreting ancient magma systems, their eruptions, and the potential future volcanic activity. In this dissertation I present the results of three projects. The first explores how magmatic processes affect magma reservoirs and eruption dynamics. The second explores where in the storage system and how often these processes occur. The third explores how volatile budgets are modified by processes such as crystallization, mixing, and assimilation. Volcán Popocatépetl (central México) erupted ~14100 14C yr BP producing the Tutti Frutti Plinian Eruption (TFPE). The eruption tapped two different silicic magmas that mixed just prior and during the eruption. The influx of mass and volatiles generated during the mixing of both magmas overpressured the reservoir, which was weakened at the top. The weakened reservoir relaxed while magma was tapped and collapsed to form a caldera at the surface. Although it is known that fractional crystallization, mixing, and assimilation can greatly modify magmas, the frequency and intensity of these events is not known. I investigated the magmatic processes responsible for the evolution of magmas erupted during five Plinian events of Popocatépetl volcano. Results show that during the last 23 ky magma was stored in two different zones, and was variably modified by replenishments of mafic magma. Interestingly, little evidence for large mafic inputs triggering explosive eruptions was found. Each of these processes alters the abundances of volatiles and introduces different types of volatiles to the system. Hence, the volatile budget of magma can have a rich and complex history. To investigate how volatile budgets evolve in active magma systems, I analyzed the abundances of volatiles (H2O, CO2, F, Cl, and S) in numerous glass inclusions trapped in phenocrysts. Results show that the magmas that produced the last five Plinian eruptions at Popocatépetl volcano evolved by crystallization and magma mixing, assimilation of the local carbonate basement is not chemically appreciable. Mixing with mafic magmas added substantial CO2 and S to the system, dewatered the magma, yet produced little change in the F contents of the magmas.

Book Synopsis Constraining the Magmatic Evolution of the Andean Arc at 21°S Using the Volcanic and Petrologic History of Volcá́n Aucanquilcha, Central Volcanic Zone, Northern Chile by : Erik W. Klemetti

Klemetti and published by . This book was released on 2005 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcan Aucanquilcha, a Pleistocene to Recent composite volcano in northern Chile, is the youngest and center-most member of the 11 m.y.-old Aucanquilcha Volcanic Cluster (AVC). The AVC has produced [approximately]350 km3 of lava over its history. Magmatism started slowly and was punctuated by high rates of eruption between 4.5 and 2.5 Ma. The AVC records a history of progressive fractionation and homogenization as the upper crustal becomes thermally and compositionally buffer through repeated intrusion. The pattern of volcanism at the AVC, from diffuse to central, mimics that seen in exposed intrusive bodies. The AVC is likely the volcanic record of the incremental emplacement of an intermediate batholith over a span of at least 11 million years. Volcan Aucanquilcha has produced [approximately] 37 km3 of compositionally and mineralogically monotonous dacite over the past 1 million years. The volcano has erupted dominantly effusive dacite lava flows with one debris avalanche deposit and one dome collapse pyroclastic flow. It also contains a ubiquitous bimodal amphibole population of hornblende and pargasite phenocrysts. P-T data from amphibole and Fe-Ti oxides indicate a multilevel geometry for the magmatic system within the top 10-km of the upper crust. The generation of magma at Aucanquilcha begins with intrusion of andesite that fractionates to mafic dacite. Magmas will then either mix with low [delta]180 upper crustal and creating a high-K dacite or will continue to fractionate to silicic dacite. In both cases, two similar dacite magmas, stored at different P-T condition mix rapidly during eruption. The repeated intrusion of magma into the upper crust during the history of the AVC has allowed for thermal and compositional buffering of the crust, creating the conditions for Volcan Aucanquilcha to erupt monotonous dacite lava. The location of eruptive vents appears to be controlled by crustal lineaments that not only focus hydrothermal fluids but may allow for the eruption of the relatively degassed dacite. Otherwise, the lavas of Aucanquilcha may have stalled underground to form a porphyry-style stock.

Book excerpt: It's 1968 and one communal house in West London, home to the last, desperate remnants of an Aboriginal tribe, echoes with drum-calls and unintelligible chants. And it reeks of blood?the animal blood used in divination rituals and the blood of the tribe's murdered chief. Detective Jimmy Pibble specializes in the peculiar, but he's never before had to play anthropologist. How do you solve a crime when you don't speak the language and you don?t understand the community's most basic assumptions?like what makes a woman different from a man, or how one tells the dead from those who are still among the living?
