This book was released on 1999 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail débouche sur deux applications. D'une part, la base de données constituée permet de mieux comprendre les propriétés pétrophysiques en relation avec la pétrographie. D'autre part, la calibration pétrophysique en laboratoire a servi pour mettre au point une méthode de prédiction de lithofaciès et faciès pétrophysiques. Cette technique, basée sur des statistiques multivariées classiques, permet d'interpréter les diagraphies de puits en intervalles non carottés.
Book Synopsis Palaeoenvironmental Reconstruction of the Mufara Formation (Upper Triassic, Sicily) by : Alexis Carrillat

This book was released on 2001 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette étude apporte une nouvelle contribution à la reconstruction du cadre géologique et paléoenvironnemental de la Formation Mufara (Trias supérieur, Sicile), et à la compréhension de l'évolution paléogéographique de la Néotethys. Les investigations intègrent l'analyse sédimentologique, l'analyse qualitative et quantitative des palynofaciès, la pyrolyse Rock-Eval, l'analyse des isotopes stables ([delta]13C et [delta]18O), la biostratigraphie haute résolution, et la stratigraphie génétique. L'analyse des palynofaciès et l'analyse des microfaciès ont permis de proposer un nouveau modèle environnemental pour la Formation Mufara. L'étude palynologique indique que les dépôts de la Formation Mufara se sont sédimentés entre le Longobardien terminal/Cordévolien basal et le Tuvalien terminal (Carnien). Quatre assemblages palynologiques ont été mis en évidence à l'intérieur de la phase à "Camerosporites secatus". Les analyses géochimiques associées aux palynofaciès confirment l'origine essentiellement terrestre de la matière organique et indiquent que celle-ci s'est accumulée sous des conditions oxiques à suboxiques.

Available in PDF, EPUB and Kindle. Book excerpt: Des investigations sismiques et sédimentologiques ont été entreprises dans le but d'étudier l'évolution sédimentaire de la région au large de Nyon, en relation avec les processus lacustres et les changements climatiques qui ont eu lieu depuis le retrait du glacier du Rhône (18000 années BP) jusqu' à aujourd'hui. La source des sédiments a progressivement changé des eaux de fonte glaciaires aux cours d'eau locaux et un cône deltaïque, alimenté par les apports de la Promenthouse, de l'Asse et du Boiron, a commencé à se former dans la partie occidentale du Lac Léman. D'importants changements des apports sédimentaires ont eu lieu au cours de l'Holocène: six différents lobes deltaïques, progradant sur les sédiments tardiglaciaires, ont été reconnus au milieu du bassin par l'analyse séismostratigraphique. L'étude des propriétés magnétiques des séquences sédimentaires récoltées a fourni une courbe des variations séculaires du champ magnétique terrestre pour les derniers 16000 ans.

This book was released on 2003 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'origine des gisements polymétalliques du Domo de Yauli est liée au magmatisme Miocène ayant affecté les Andes péruviennes. Cette étude met en évidence les relations géochronologiques et structurales entre les intrusions et les corps minéralisés, ainsi que les caractéristiques des fluides hydrothermaux. Les âges obtenus sur les intrusions et les minéralisations indiquent un système pulsé et répétitif durant 9 Ma, alors que les contraintes associées à la formation des gisements montrent un champ hétérogène probablement lié à l'influence de linéaments crustaux. Les rapports isotopiques de Sr, Pb, O et H associés à l'étude des inclusions fluides, par microthermométrie, spectroscopie Raman et LA-ICP-MS, révèlent l'influence d'au moins trois fluides d'origines et de caractéristiques différentes. Leur mélange a conduit à la formation des gisements, alors que les éléments économiquement intéressants ont uniquement été apportés par le fluide s'étant séparé du magma.

Book Synopsis High-resolution Seismic Facies of Alluvial Depositional Systems in the Lower Freshwater Molasse (Oligocene-early Miocene, Western Swiss Molasse Basin) by : Didier Morend
Download or read book High-resolution Seismic Facies of Alluvial Depositional Systems in the Lower Freshwater Molasse (Oligocene-early Miocene, Western Swiss Molasse Basin) written by Didier Morend and published by . This book was released on 2000 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: This PhD research showed the contribution of the high-resolution seismic reflection method to the seismic stratigraphic analysis of variable-scale, alluvial depositional systems in the Lower Freshwater Mollasse of the western Swiss Molasse Basin. Seismic data acquired offshore with an airgun source imaged alluvial architectural elements. Metre-thick, channel-fill complexes and flood plain deposits were clearly distinguished. On land, two types of data were recorded, each with a different source : in-hole shotgun and explosives. Data acquired with the former source imaged sandstone-filled multistory channels, but the resolution was not high enough to define their internal structure. The frequency content of the data recorded with explosives did not surely permit the distinction between sandstone- and shale-dominated bodies. More generally, the results demonstrated the potential of the method for predicting subsurface lithologies in cemented fluvial deposits, in association with outcrop and borehole studies.

Book Synopsis Mineralogical and Geochemical Changes of Copper Flotation Tailings in Relation to Their Original Composition and Climatic Setting by : Bernhard Dold
Download or read book Mineralogical and Geochemical Changes of Copper Flotation Tailings in Relation to Their Original Composition and Climatic Setting written by Bernhard Dold and published by . This book was released on 1999 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the present work six flotation tailings impoundments at five flotation plants (Piuquenes, Cauquenes, El Salvador, Ojancos, P. Cerda) located in different climatic zones of Chile were selected to investigate the mineralogical and geochemical changes taking place in copper flotation tailings subsequent to sulfide oxidation, especially the formation of acid mine drainage and element mobility. Results show the importance of primary mineralogy (acid producing and acid neutralizing minerals) in controlling the mobility of the liberated elements due to pH control. Climatic conditions control the element mobilization directions (humid = downwards; arid = upwards) and so the geochemical conditions where these elements may precipitate as secondary minerals (humid = reducing conditions below the water table; arid = oxidizing conditions at the surface). The climate controls so the secondary mineralogy and thus the availability of hazardous heavy metals to the environment. Additionally the impoundment construction technique may influence the mobilization and enrichment processes.
Book Synopsis The Petrology and Geochemistry of Diverse Crustal Xenoliths, Tatara-San Pedro Volcanic Complex, Chilean Andes by : Fidel Costa Rodriguez
Download or read book The Petrology and Geochemistry of Diverse Crustal Xenoliths, Tatara-San Pedro Volcanic Complex, Chilean Andes written by Fidel Costa Rodriguez and published by . 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.
Book Synopsis Linking Diagenesis to Sequence Stratigraphy by : Sadoon Morad
Download or read book Linking Diagenesis to Sequence Stratigraphy written by Sadoon Morad and published by John Wiley & Sons. This book was released on 2012-11-05 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sequence stratigraphy is a powerful tool for the prediction of depositional porosity and permeability, but does not account for the impact of diagenesis on these reservoir parameters. Therefore, integrating diagenesis and sequence stratigraphy can provide a better way of predicting reservoir quality. This special publication consists of 19 papers (reviews and case studies) exploring different aspects of the integration of diagenesis and sequence stratigraphy in carbonate, siliciclastic, and mixed carbonate-siliciclastic successions from various geological settings. This book will be of interest to sedimentary petrologists aiming to understand the distribution of diagenesis in siliciclastic and carbonate successions, to sequence stratigraphers who can use diagenetic features to recognize and verify interpreted key stratigraphic surfaces, and to petroleum geologists who wish to develop more realistic conceptual models for the spatial and temporal distribution of reservoir quality. This book is part of the International Association of Sedimentologists (IAS) Special Publications. The Special Publications from the IAS are a set of thematic volumes edited by specialists on subjects of central interest to sedimentologists. Papers are reviewed and printed to the same high standards as those published in the journal Sedimentology and several of these volumes have become standard works of reference.
