*CHIME dating of monazite, xenotime, zircon and polycrase: protocol, pitfalls and chemical criterion of possibly discordant age data Invited Reviewed

Language：English Publishing type：Research paper (scientific journal)

This paper outlines the CHIME (chemical Th-U-total Pb isochron method) dating on the basis of precise electron microprobe analyses of Th, U and Pb in Th- and U-bearing accessory minerals such as monazite, xenotime, zircon and polycrase, and the age-mapping technique applicable to young monazite and zircon. The CHIME dating consists in measuring many spots within constant age domains showing sufficient compositional variation, and in constructing a "pseudo-isochron" from which an age can be obtained by regression. This method, coupled with discrimination of possibly concordant age data by chemical criteria like the (Ca+Si)/(Th+U+Pb+S) ratio for monazite and Ca and S contents for zircon, has the potential advantage of significant precision, and the ability to work with minerals having substantial initial Pb, and can identify two or more homogeneous domains that are separated by an age gaps smaller than the error on individual spot analysis of age. Many features that are insignificant in major element analysis can have major manifestation in acquired trace elements. Critical comments include the roles of collimator slit, detector gas, background estimation, accelerating voltage, probe current, X-ray interferences and count-rate in affecting the accuracy, and a way to access the Th and U interference correction without pure Th- and U-oxides or synthesized pure ThSiO<SUB>4</SUB>.
