We present preliminary results from a compilation of abundance data for stars in the Catalog of Nearby Habitable Systems (Turnbull, M.C. and Tarter, J.C 2003, ApJS, 145, 181). "HabCat" contains a listing of star systems which conceivably have habitable planets and so our focus has been on those bio-essential elements, namely: C, N, O, Mg, S, and Ti. We have mapped the spectroscopically determined abundances in 3D and also 2D slices, for deterministic trends that occur both spatially and with regard to representative elements. These element abundance maps illustrate nucleosynthesis patterns within 500ly of the Sun which may include potential hosts to Earthlike planets.
