We hope that this monograph series will by pass these problems in fulfilling the need. P. J. WYLLIE, Chicago, Ill. Preface Sub-series on "Isotopes in Geology".

Metasomatic alteration of accessory minerals such as zircon or monazite can allow for the dating of metasomatic events as well as give additional information of geologists, each of whose specialities and long range experience regarding one or more aspects of metasomatism during geologic processes, should allow

Rollin E. Stevens, 1960. 7. Geochronology: Linking the Isotopic Record with Petrology The same problem arises also for the dating of monazite, xenotime and allanite. These rare earth element (REE)-rich minerals may derive their REE content from the breakdown of a REE-rich precursor rather than major minerals.

8 mai 2017 Subsequent U and Th decay in these new crustal rocks added more Pb isotopes to their initial inherited Pb isotopic composition. These minerals include uraninite, zircon, baddeleyite, monazite, apatite, and sphene (titanite). It is virtually free of U and Th, so the appreciable concentration of Pb in it has then
