Rb-Sr and U-Pb geochronology of neoblasts and porphyroclasts constrain movements along reactivated segments of the Outer Hebrides Fault Zone, NW Scotland

The crustal-scale Outer Hebrides Fault Zone (OHFZ) (NW Scotland) was initiated as a Stenian-Tonian (1040-950 Ma) ductile thrust, as determined by published U-Pb dating of syn-kinematic apatite. Thrust-related mylonites were then reactivated to form phyllonite belts during success...
