New Techniques Applied to the U-Pb Method at the Centre for Geochronological Research of the University of São Paulo: Chemical Digestions, TIMS Mass Spectrometry and Examples of Integrated Application of SHRIMP

The present work describes new techniques of U-Pb ID-TIMS developed at the CPGeo-IGc/USP. Techniques of partial and total chemical digestions, U and Pb concentration using anion exchange in a micro column, and the utilization of a 205Pb spike are discussed. Main geochronological equations used are a...
