Abstract:
During the Meteor 79/3 expedition on the Cabo Verde Archipelago/NE Atlantic region, rock samples were obtained using a dredge haul. 40Ar-39Ar laser total fusion geochronological analyses have been performed on K-feldspar and biotite single-/multi-crystal separates from one sample (950-2). The 40Ar-39Ar analyses were determined using a MAP216 mass spectrometer at GEOMAR, a MAP argon extraction line and a 25 W Coherent Sabre 25TSM argon ion laser, from 30th August 2017 until 2nd September 2017. The Taylor Creek sanidine (TCS2) flux standard was used with an age of 27.344 +/- 0.011 Ma (1 sigma error; Fleck et al. 2019).
