In this work, we aim to have a better understanding of the genesis of podiform chromitites by carefully classifying and comparing the concordant and discordant podiform chromitite types in the Acoje and Coto blocks of the Zambales Ophiolite Complex, Philippines. Our recent fieldwork revealed that the Acoje block solely contains concordant podiform chromitites whereas only discordant chromitites were observed in the Coto block. PGE data obtained using Ni-sulfide fire assay revealed that the high Cr podiform chromitites of the Acoje block have significantly higher PGE contents compared to the Coto block. Based on our initial results, we expect to find further petrological and geochemical differences between these two contrasting podiform types which may help elucidate the possible origin of podiform chromitites.
