Lithological, rheological, and fluid infiltration control on 40Ar/39Ar ages in polydeformed rocks from the West Cycladic detachment system, Greece

In situ ultraviolet (UV) laser-ablation 40Ar/39Ar dating, microstructural analysis, and stable O, H, and C isotope analyses were performed on white mica-bearing calcite- and quartz-mica schists of the West Cycladic detachment system footwall in order to resolve outstanding uncertainties about the ti...
