Stellar absorption line profiles and equivalent widths are measured from high resolution INT and AAT optical spectra of four high galactic latitude targets and used in conjunction with model atmosphere codes to determine their atmospheric parameters and chemical compositions. Normal Population I abundances are derived, with typical errors of ±0.2 dex, implying z-distances in the range 1 - 2 kpc. Various explanations for the existence of such stars so far from the galactic plane are discussed, the most likely mechanism being cluster ejection.
