THE ORIGIN OF THE METAL ENRICHMENT OF THE INTRACLUSTER MEDIUM (ICM) REPRESENTS A FUNDAMENTAL PROBLEM IN EXTRAGALACTIC ASTROPHYSICS WITH IMPLICATIONS FOR OUR UNDERSTANDING OF HOW STARS AND GALAXIES FORM THE NATURE OF TYPE IA SUPERNOVA (SNIA) PROGENITORS AND THE THERMAL HISTORY OF THE ICM. THESE HEAVY ELEMENTS ARE ULTIMATELY SYNTHESIZED BY SUPERNOVA (SN) EXPLOSIONS; HOWEVER THE DETAILS OF THE SITES OF METAL PRODUCTION AND MECHANISMS THAT TRANSPORT METALS TO THE ICM REMAIN UNCLEAR. TO MAKE PROGRESS ACCURATE ABUNDANCE PROFILES FOR MULTIPLE ELEMENTS EXTENDING FROM THE CLUSTER CORE OUT TO THE VIRIAL RADIUS (R180) ARE REQUIRED FOR A SIGNIFICANT CLUSTER SAMPLE. WE PROPOSE AN X-RAY SPECTROSCOPIC STUDY OF A CAREFULLY-CHOSEN SAMPLE OF ARCHIVAL SUZAKU AND XMM-NEWTON OBSERVATIONS OF 23 CLUSTERS: XMM-NEWTON DATA PROBE THE CLUSTER TEMPERATURE AND ABUNDANCES OUT TO (0.5-1)R500 WHILE SUZAKU DATA PROBE THE CLUSTER OUTSKIRTS. A METHOD DEVISED BY OUR TEAM TO UTILIZE ALL ELEMENTS WITH EMISSION LINES IN THE X-RAY BANDPASS TO MEASURE THE RELATIVE CONTRIBUTIONS OF SUPERNOVA EXPLOSIONS BY DIRECT MODELING OF THEIR X-RAY SPECTRA WILL BE APPLIED IN ORDER TO CONSTRAIN THE DEMOGRAPHICS OF THE ENRICHING SUPERNOVA POPULATION. IN ADDITION WE WILL CONDUCT A STACKING ANALYSIS OF OUR ALREADY EXISTING SUZAKU AND XMMNEWTON CLUSTER SPECTRA TO SEARCH FOR WEAK EMSSION LINES THAT ARE IMPORTANT SN DIAGNOSTICS AND TO LOOK FOR TRENDS WITH CLUSTER MASS AND REDSHIFT. THE FUNDING WE PROPOSE HERE WILL ALSO SUPPORT THE DATA ANALYSIS OF OUR RECENT SUZAKU OBSERVATIONS OF THE ARCHETYPAL CLUSTER A3112 (200 KS EACH ON THE CORE AND OUTSKIRTS). OUR DATA ANALYSIS INTEPRETED USING THEORETICAL MODELS WE HAVE DEVELOPED WILL ENABLE US TO CONSTRAIN THE STAR FORMATION HISTORY SN DEMOGRAPHICS AND NATURE OF SNIA PROGENITORS ASSOCIATED WITH GALAXY CLUSTER STELLAR POPULATIONS -- AND HENCE DIRECTLY ADDRESESS NASA S STRATEGIC OBJECTIVE 2.4.2 IN ASTROPHYSICS THAT AIMS TO IMPROVE THE UNDERSTANDING OF HOW THE UNIVERSE WORKS AND EXPLORE HOW IT BEGAN AND EVOLVED.
