Workshop on the Chronology of Meteorites and the Early Solar System : November 5-7, 2007, Kauai, Hawaii

Abstract

This interdisciplinary meeting is aimed at understanding the chronology of the processes in the early solar system as revealed by meteorites. This includes the astrophysical setting of solar system formation, the origin of short-lived radioisotopes, and the chronology of nebular and asteroidal processes: formation of chondrules, refractory inclusions and matrices of primitive chondrites, timing of accretion and thermal processing (aqueous alteration, thermal metamorphism, and igneous differentiation) of asteroids and comets. The workshop will review recent advances in long-lived and short-lived isotope systematics with the goal of reconciling long-lived and short-lived isotope chronologies, as well as potential chronological significance of O-isotopes. The workshop will also address technical aspects (i.e., limitations, advantages, precision, accuracy, interlaboratory calibration) of various analytical techniques used in cosmochronology such as LA-MC-ICPMS, MC-ICPMS, SIMS, and TIMS. An important goal of the workshop is to identify outstanding questions and establish future research directions.
