Pb isotopic study of early solar system materials

Abstract

Pb isotopic chronometer can serve as a valuable tool in unraveling the history of the early solar system not only because it can provide us with the absolute age of the planetary materials but also because it can, upon meeting certain requirements, determine the age of planetary materials with an uncertainty of few million years or less. In this talk, I would like to introduce some of my recent work on the Pb isotopic systematics of chondritic meteorites, and discuss about possible future which this work may lead to.
