We performed simultaneous spectral analysis of 26.6 ksec of Chandra and 102.3ksec of Suzaku X-ray data of the starburst galaxy NGC 3079. The spectra areextracted from four regions: 0.5' (2.25 kpc) circle, an inner 0.5'-1'(2.25--4.5 kpc) ring, and an outer 1'-2' (4.5--9 kpc) ring from Chandra, and 4'(18 kpc) circle from Suzaku, all centered on the nucleus. Fitting with thermalplasma models yields interstellar medium (ISM) temperatures of 0.65+0.05-0.04,0.45+0.07-0.06, and 0.24+0.03-0.02 keV in the three regions, respectively. Thecombination of Chandra's high angular resolution and Suzaku's good spectralsensitivity enable us to spatially resolve and measure the abundances of themetals O, Ne, Mg, and Fe within the hot ISM. In particular, the abundancepatterns of O/Fe, Ne/Fe, Mg/Fe, and Si/Fe in the central regions (<4.5 kpc) areconsistent with the expectations from Supernovae (SN) II synthesis. On theother hand, the pattern in the region beyond 4.5 kpc is closer to solar. Thecentral regions are also where copious polycyclic aromatic hydrocarbon infraredemission related to recent starburst activity is known to occur. This suggeststhat we are seeing starburst-related SN II metal enrichment in the hotX-ray--emitting nuclear ISM. The spatial extent of the SN II--like abundancepatterns is consistent with NGC 3079 being in a relatively-early phase ofstarburst activity.
