Transition from exhumation to orogen-parallel extension in the Adula unit (Central Alps)
Description
The Adula unit (Central Alps) exposes high- and ultra-high-pressure (HP-UHP) metamorphic rocks, providing key insights into the subduction and exhumation dynamics of the former distal European margin. In the San Bernardino pass area (Switzerland) it is possible to reconstruct the tectonometamorphic evolution or the Adula unit from HP conditions to exhumation and subsequent shearing during orogen-parallel extension. The P-T-d-t evolution of eclogites and host rocks fhas been determined by thermodynamic modelling and Ar-Ar dating of syntectonic minerals. This dataset contains location and description of studied samples, mineral chemistry data obtaine by electron microprobe analyses and Ar-Ar data on white micas in eclogites and hosting orthogneisses.
