This book was released on 2000 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deux groupes de xénolites ont été échantillonnés dans une lave dacitique du Volcán Holocène San Pedro (Andes du Chili ; 36°S, 71°51'W). Le groupe I est constituté de mélanorites à olivine qui sont co-magmatiques au volcanisme Holocène. Le groupe II consiste en des leuconorites à clinopyroxène et hornblende qui représentent des fragments du soubassement pré-quarternaire du volcan. Malgré leur différence d'âge et d'origine, ces deux groupes de xénolites ont enregistré des processus de migration de liquides riches en Si02 et H2O ou de fluides aqueux qui ont réagit avec l'olivine, le spinelle, les pyroxènes ou le plagioclase pour former d'importantes quantités de horblende (50%) et phlogopite (12%), expliquant ainsi l'abondance de hornblende dans les plutons gabbroïques calco-alcalins, comparée aux laves basaltiques ou basaltiques andésitiques présentes dans les zones de subduction.

This book was released on 2013 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study aims to evaluate the processes by which ocean island basalt-derived mantle xenoliths are depleted and, in some cases, subsequently re-fertilized using extremely depleted mantle xenoliths from Lanzarote, Canary Islands. New petrography, mineral-chemistry and whole-rock data are reported for>40 Lanzarote xenoliths, ranging from ultra-depleted harzburgites to re-fertilized lherzolites and gabbroic crustal samples. Previous studies of mantle xenoliths from Lanzarote report whole rock and mineral chemistries for only general categories of mantle peridotites, e.g. dunites, protogranular harzburgites and lherzolites, and melt-influenced textured xenoliths. In these studies, there are few detailed textural and chemical sample-specific connections reported. This study investigates and reports on chemistries and textures of individual samples, as they prove to be intrinsically related. These samples come from a total of six separate sampling sites on Lanzarote, representing one of the most comprehensive petrological studies yet performed on xenoliths from any oceanic island. This study focuses on identifying levels of melt depletion and later melt infiltration into mantle xenoliths and to provide a framework for understanding processes acting on the mantle beneath the Canary Islands.

Download or read book Crust Mantle and Lithosphere Asthenosphere Boundaries written by Gianluca Bianchini and published by Geological Society of America. This book was released on 2017-05-10 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 10-chapter volume encompasses contributions from a wide spectrum of Earth science disciplines, including geophysics, geodynamics, geochemistry, and petrology, to provide an overview of the nature and evolution of the crust-mantle and lithosphere-asthenosphere boundaries in different tectonic settings, combining studies that exploit different types of data and interpretative approaches. The integration of geochemical, geophysical, and geodynamic data sets and their interpretation provides a state-of-the-art summary of current understanding, and will serve as a blueprint for future research activities.
