Cosmogenic exposure age dating

Seeking mechanistic, quantitative understanding of the form and evolution of landscapes.

In addition, we are seeking linkages between ecological and geomorphic processes, and building tools to tackle pressing environmental problems.

Auch die Entwicklung und Verwendung isotopengeochemischer Methoden in der Geo- und Kosmochemie sind ein Forschungsschwerpunkt. Special Section, Geochimica et Cosmochimica Acta 55, p.

Diese Forschungen wurden finanziell durch den sterreichischen FWF und (unter anderem) das International Continental Drilling Program (ICDP) untersttzt. Weiters wurde 2009 eine Tiefbohrung am El'gygytgyn Meteoritenkrater im arktischen Teil Russlands durchgefhrt, wobei im Rahmen eines internationalen Projektes sowohl Paloklimafragen als auch die Untersuchung des Meteoritenkraters im Mittelpunkt stehen. An attempt is made here to thoroughly examine these arguments, and the counter arguments made by detractors, in the light of a sizable cross-section of the available literature on the subject.Of the techniques that have been used to measure the meteoritic dust influx rate, chemical analyses (of deep sea sediments and dust in polar ice), and satellite-borne detector measurements appear to be the most reliable.However, upon close examination the dust particles range in size from fractions of a micron in diameter and fractions of a microgram in mass up to millimetres and grams, whence they become part of the size and mass range of meteorites.Thus the different measurement techniques cover different size and mass ranges of particles, so that to obtain the most reliable estimate requires an integration of results from different techniques over the full range of particle masses and sizes.Around 35 people from various research institutions, service providers and the mining industry attended the workshop from across Australia. The day started with a tour of the John de Laeter Centre (Jd LC) facilities incorporating the Tescan integrated mineral analyser (TIMA; ), which was the key instrument of relevance to the workshop. 700 Millionen Jahren (die sogenannten "Snowball Earth" Phasen), der frhesten Entwicklung der Erde vor ca.
