Abstract
Conventional U-Pb ages on zircon and monazite demonstrate that granites
and gabbros intruded during a short time span of 5 Ma between 293 and
288 Ma in several polycyclic basement units of the Western Austroalpine
domain. This bimodal activity reflects increasing underplating of an
upwelling mantle at the base of a thinning post-Variscan continental
crust.
