    Notes: Abstract Intermediate resolution (λ/δλ ∼ 25 000) CCD spectra of the oxygen triplet at λ7770 Å have been analyzed to determine oxygen abundances in a sample of metal-deficient stars with metallicities covering the range −2.5≤[Fe/H]≤−0.2. Important oxygen overabundances ([O/Fe]≥1) are found in the more metal deficient stars of the sample. We briefly discuss the information that these observations provide about the early nucleosynthesis history and chemical evolution of the Galaxy.
