Jan Zalasiewicz, Professor für Paläobiologie an der University of Leicester, befasst sich mit dem Anthropozän.
Jan Zalasiewicz ist Professor für Paläobiologie an der University of Leicester, UK. Zu Beginn seiner Karriere war er Feldgeologe und Paläontologe beim British Geological Survey und arbeitete an der Entschlüsselung der Schichten Ostenglands und dann der Berge Zentralwales. Jetzt unterrichtet er Geologie und Erdgeschichte für Studenten und Doktoranden und untersucht fossile Ökosysteme und Umwelten über eine halbe Milliarde Jahre geologischer Zeit. In den letzten Jahren war er an der Entwicklung von Ideen zum Anthropozän beteiligt, dem Konzept, dass Menschen heute viel Geologie auf der Erdoberfläche vorantreiben, und leitet die Anthropozän-Arbeitsgruppe der Internationalen Kommission für Stratigraphie.
Volcanoes (A very short Introduction) pdf von Jan Zalasiewicz
Volcanoes are some of the most dramatic expressions of the powerful tectonic forces at work in the Earth beneath our feet. But volcanism, a profoundly important feature of Earth, and indeed of other planets and moons too, encompasses much more than just volcanoes themselves. On a planetary
scale, volcanism is an indispensable heat release mechanism, which on Earth allows the conditions for life. IIt releases gases into the atmosphere and produces enormous volumes of rock, and spectacular landscapes - landscapes which, during major eruptions, can be completely reshaped in a matter of
hours. Through geological time volcanism has shaped both climate and biological evolution, and volcanoes can affect human life, too, for both good and ill. Yet, even after much study, some of the fundamental aspects of volcanicity remain mysterious.
This Very Short Introduction takes the readers into the inferno of a racing pyroclastic current, and the heart of a moving lava flow, as understood through the latest scientific research. Exploring how volcanologists forensically decipher how volcanoes work, Michael Branney and Jan Zalasiewicz
explain what we do (and don't) understood about the fundamental mechanisms of volcanism, and consider how volcanoes interact with other physical processes on the Earth, with life, and with human society.
