40Ar/39Ar ages from hornblende, biotite and muscovite collected from the Marsyangdi valley of central Nepal

This dataset contains 40Ar/39Ar bedrock ages measured from 20 hornblende, 9 biotite, and 40 muscovite grains collected from the Marsyangdi valley of central Nepal. The samples were all collected from medium to high-grade metamorphic rocks, to add to already available thermochronometric datasets in the region, and better constrain the exhumation history of the central Himalayas. Measurement of the hornblende and biotite ages were performed using a step-heating method. However, measurement of the muscovite ages was performed using either a step-heating, or a total fusion method
