Objectif(s): To apply paleomagnetism to date extensive collections of pollen and megaflora from the Eureka Sound Group; to test correlations of a magnetostratigraphic section to the geomagnetic time scale; to establish a dated reference section for the Late Cretaceous-Paleogene arctic.
Description du projet: For much of the Earth's history, the arctic has had a mild climate, quite unlike the conditions that now exist. Evidence that supports this past climate are fossil plants and animals (including crocodiles and tortoises) found in the arctic. The Earth's magnetic field has changed over time and these changes are contained in the fossils. This research will try develop a technique to age these fossils by measuring their magnetic characteristics.
