CA-LA-ICP-MS age data are in good agreement with the CA-ID-TIMS dates and suggest advantages of using CA-LA-ICP-MS in order to define accurate ages.
The use of the CA technique for very young zircons (∼0.2 Ma, Kos rhyolitic tuff, Greece) seems optional; as the obtained mean U ages of non-CA and CA treated zircons coincide within the uncertainty.
It was also revealed that the Toya Tephra magma crystallized zircons and experienced eruptions instantaneously at ~ 0.1 Ma, which is an important implication to decipher magmatic and eruptive processes for caldera-forming large volcanic systems.
Registered users receive a variety of benefits including the ability to customize email alerts, create favorite journals list, and save searches.
Nevertheless, the results of this study provide an example of the type of precision and accuracy that may be possible with this technique under ideal conditions.
