  We present the abundances of the intermediate elements obtained by performing
a stacked analysis of all the galaxy clusters in the archive of the X-ray
telescope ASCA. We give the abundances of Fe, Si, S, and Ni as a function of
cluster temperature from 1--10 keV, and place strong upper limits on the
abundances of Ca and Ar. We show that the abundances of the most
well-determined elements Fe, Si, and S in conjunction with recent theoretical
supernovae yields do not give a consistent solution for the fraction of
material produced by Type Ia and Type II supernovae at any single temperature.
However, the general trend is for higher temperature clusters to have more of
their metals produced in Type II supernovae than in Type Ias.
