Using volcaniclastic rocks to constrain sedimentation ages: To what extent are volcanism and sedimentation synchronous?

Volcaniclastic rocks are commonly used to date sedimentary series since absolute ages are routinely obtained from several geochronological methods. In this work, we present five selected geochronological studies (U-Pb on zircon) on late Paleozoic to Mesozoic volcaniclastic series from Asia, with the aim of discussing if absolute ages obtained on volcaniclastic rocks can be used directly to date sedimentation. For all these volcaniclastic series,...
