EARTHTIME: Progress and Updates II


Session ID#: 8706

Session Description:
Precise and accurate multi-proxy timescales are required to understand the fundamental processes of the Earth System, such as biological evolution, adaptive radiations, catastrophic climate events, mass extinctions and recoveries, and rates of global climate change Tremendous progress has been made toward establishing a high resolution Geologic Time Scale in the past decade because of a broad community engagement in EARTHTIME (a international-community-based scientific initiative whose main goal is the development and application of the geochronological techniques necessary to produce temporal constraints with uncertainties approaching 0.1 percent of the radioisotopic ages). We invite abstracts, including but not limited to, calibration of methods and inter-laboratory and inter-method experiements in radioisotopic measurements, integration of geochronology, magnetic stratigraphy, astrochronology, and chemostratigraphy towards the goal of refining the Geologic Time Scale and documenting the sequences and the tempo of important events and intervals in Earth History.
