We present the results of a spectroscopic survey of X-ray-selected, low-mass candidate members of the young open cluster NGC 2547. Using a combination of photometry, spectroscopic indices and radial velocities, we refineour candidate list and then use our spectroscopy to study the progression of lithium depletion in low-mass pre-main-sequence stars. We derive lithium abundances or upper limits for all our candidate members, which have effective temperatures in the range 5000 > T e f f > 3200 K…
