    Metal K-edge X-ray absorption spectra of Mn, Mn/(Fe), Cu/In, Cu/In/(Fe) and Cd doped zinc sulfides are reported. The Zn K-edge XANES shows that there is little change on the low-lying vacant electronic states of the Zn. Furthermore, the Zn EXAFS indicates that the coordination site of the Zn is almost unchanged by any of the dopants. Mn, Cu, In and Cd K-edge EXAFS show that the local S tetrahedra around the dopant are compressed for Cu and expanded for Mn, In and Cd. Moreover the second coordination sphere indicates that clustering occurs in the Cu/In- and Cd-doped materials. M-S bond distances of the dopants in sphalerite are: Cd-S, 2.48 Å In-S, 2.43-2.45 Å, Cu-S, 2.30-2.33 Å and Mn-S, 2.41-2.43 Å.
