Sedimentology and Stratigraphy

Umfassendes Lehrwerk ü ber sä mtliche Aspekte der Sedimentologie und der grundlegenden Stratigraphie

Das Buch Sedimentology and Stratigraphy fü hrt in die Thematik ein und gibt den Leserinnen und Lesern Werkzeuge zur Interpretation von Sedimenten und Sedimentgesteinen an die Hand. Dabei werden die Prozesse der Bildung, des Transports und der Ablagerung von Sedimenten behandelt und auf die Entwicklung konzeptioneller Modelle fü r sä mtliche Sedimentumgebungen ? von Wü sten ü ber die Tiefsee und Riffe bis zu Flü ssen ? angewandt. Fü r einen umfassenden Ü berblick ü ber sä mtliche Aspekte der Sedimentologie und Stratigraphie werden auß erdem verschiedene Ansä tze zur Nutzung stratigraphischer Prinzipien bei der Datierung und Korrelierung von Schichten betrachtet.

Die 3. Auflage wurde grü ndlich ü berarbeitet und aktualisiert. Dabei wurde die Kapitelgliederung so geä ndert, dass nun separate Abschnitte zur Geomorphologie und zur Stratigraphie fü r jede Sedimentumgebung vorhanden sind. Auß erdem enthä lt die neue Ausgabe zusä tzliche farbige Abbildungen.

Die wesentlichen Konzepte, die in Sedimentology and Stratigraphy eingefü hrt werden, umfassen u. a. :
* Die Bedeutung von Verä nderungen in der Pflanzen- und Tierwelt im Zeitverlauf und die Auswirkungen auf die Charakteristik des Sedimentumfelds im Meer und an Land
* Die Unterscheidung zwischen modernen Umgebungen und dem, was in den Sedimentabfolgen erhalten geblieben ist, mit einer Betrachtung glazialerosionaler und von Ablagerungen geprä gter Landformen
* Heutige Wü stenumgebungen und ä olische Ablagerungen in der stratigraphischen Abfolge
* Fluviale Prozesse mit Mustern von Neben- und Verteilerkanä len unterschiedlicher Grö ß enordnung und in verschiedenen Umgebungen

Das Werk Sedimentology and Stratigraphy wurde von einem kenntnisreichen Autor mit umfangreicher Erfahrung auf dem Fachgebiet verfasst. Es ist ein gut verstä ndliches Lehrwerk fü r Studierende der Geologie und verwandter Fachgebiete, die sich Kenntnisse ü ber die Bildung, Eigenschaften und Bedeutung von Sedimentgesteinen aneignen mö chten.
