U‐Pb dating of zircon by LA‐ICP‐MS - Chang - 2006

From the U-Pb system, it is possible to obtain two isochron equations and thus two independent ages: Key Words Neptune, Laser Ablation, Multicollector ICP-MS, Multi Ion Counting, U-Pb Dating, Zircons If these two ages are the same, the data are concordant. A Concordia diagram is …

Temporal and spatial evolution of Northern Cascade Arc

Abstract LA-ICP-MS U-Pb dating of zircon is becoming an increasingly widespread geochronologic technique due to the availability of instrumentation, the relative ease of sample preparation, the short analytical time, and the reasonably precise and accurate age determinations.

LA-ICP-MS zircon U–Pb dating, trace element and Hf isotope

In this contribution, in situ LA-ICP-MS U–Pb, Hf isotope and trace element analyses of zircon crystals have been combined to constrain the emplacement time and petrogenesis of the Heyu granitic batholith which hosts the Yuchiling porphyry Mo system, Henan Province, China.
