Mixing effects in zircon U–Pb ion microprobe dating: An example from a quartzofeldspathic dyke in the Yeongdeok pluton, southeastern Korea
SHRIMP zircon dating mixing dyke
2017/4/11
A swarm of quartzofeldspathic dykes extensively intruded the Permian–Triassic Yeongdeok pluton and xenoliths therein
in southeastern Korea. Zircons from the dyke intruding a diorite xenolith yield se...
Mn/Cr relative sensitivity factors for synthetic calcium carbonate measured with a NanoSIMS ion microprobe
secondary ion mass spectrometry Mn-Cr chronology relative sensitivity carbonate isotope
2017/8/9
Mn/Cr relative sensitivities for a synthetic calcite and a terrestrial olivine (San Carlos olivine) were measured using spot and rasterized modes with a NanoSIMS ion probe. Counting rates of 43Ca+, 52...
