Research Abstract
Apatite and monazite are the waste during zircon separation, which are used for Sr and Nd measurements, respectively using laser ablation multi-collector inductively coupled plasma mass spectrometry. In this project, we successfully set up the routine from mineral separation, U-Pb dating, and Sr-Nd-Hf isotopic measurement using zircon, apatite, and monazite. This method does not require any dissolution of rocks and wet analyses, thus, it allows quite rapid and safety measurements of multi isotopes. Additionally, the isotopic data obtained from each mineral are in good agreement with those of whole rock measured by wet analyses. Using this method, we can evaluate protolith of sedimentary and metasedimentary rocks using detrital zircon, apatite, and monazite.
