Book excerpt: Il y a 28 millions d'années, l'une des plus grandes éruptions explosives connues a pris place dans le sud de l'actuel Colorado, aux Etats-Unis. Cette unité volcanique, dénommée le Tuf de Fish Canyon, ainsi que deux plus petites éruptions qui lui sont associées, ont permis d'étudier plusieurs aspects de ces phénomènes rares mais d'une puissance capable d'affecter la terre dans son ensemble. Cette thèse aborde trois sujets principaux. Tout d'abord, une étude volcanologique sur les dépôts précédant l'unité climatique a permis de documenter un style éruptif nettement moins explosif pour cette unité précurseur probablement à l'origine du déclenchement de l'éruption principale. Deuxièmement, une étude texturale et géochimique a démontré que le magma de Fish Canyon a été réactivé par une injection de basalte, menant à la remobilisation de tout le corps magmatique. Finalement, une étude géochronologique a permis de contraindre la vitesse de ces phénomènes magmatiques.

Download or read book The Eastern San Juan Mountains written by Rob Blair and published by University Press of Colorado. This book was released on 2011-09-01 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: A companion to The Western San Juan Mountains (originally published in 1996), The Eastern San Juan Mountains details the physical environment, biological communities, human history, and points of interest in this rich and diverse mountain system. A natural division between the eastern and western slopes of the San Juans is the north-south line that runs approximately through Lake City, south of the crossing of the Piedra River by US Highway 160. In this super guidebook, twenty-seven contributors--all experts in their fields--artfully bring the geology, hydrology, animal and plant life, human histories, and travel routes of these eastern slopes to life. Designed to inform researchers, educators, and students about the region's complex systems, The Eastern San Juan Mountains also serves as an informative guidebook to accompany visitors along their travels on the Silver Thread National Scenic Byway, which stretches between South Fork and Lake City. The Eastern San Juan Mountains deserves a place next to The Western San Juan Mountains on the bookshelf of every naturalist, researcher, resident, educator, student, and tourist seeking a greater understanding of this marvelous place and its history.

Available in PDF, EPUB and Kindle. Book excerpt: Volume 69 of Reviews in Mineralogy and Geochemistry covers the fundamental issues of volcanology: At what depths are eruptions triggered, and over what time scales? Where and why do magmas coalesce before ascent? If magmas stagnate for thousands of years, what forces are responsible for initiating final ascent, or the degassing processes that accelerate upward motion? To the extent that we can answer these questions, we move towards formulating tests of mechanistic models of volcanic eruptions (e.g., Wilson, 1980; Slezin, 2003; Scandone et al., 2007), and hypotheses of the tectonic controls on magma transport (e.g., ten Brink and Brocher, 1987; Takada, 1994; Putirka and Busby, 2007). Our goal, in part, is to review how minerals can be used to understand volcanic systems and the processes that shape them; we also hope that this work will spur new and integrated studies of volcanic systems.
