We present a differential abundance analysis of Hyades F-K dwarfs in searchfor evidence of stellar enrichment from accreted hydrogen deficient diskmaterial. Metallicites and relative abundance ratios of several species havebeen determined. We derive a cluster mean [Fe/H] = 0.13+-0.01. Two stars showabundances ~0.2 dex larger than the cluster mean. Additionally, one star, whichwas added by a recent study as a cluster member, shows significantly lowerabundances than the cluster mean. These three stars have questionablemembership characteristics. The remaining stars in the survey have an rms of0.04 dex in the differential [Fe/H] values. The Hyades cluster members haveapparently not been significantly chemically enriched. The abundance ratios ofSi, Ti, Na, Mg, Ca and Zn with respect to Fe are in their solar proportions.Comment: 19 pages, 5 figures and 7 tables.
