This report presents petrographic data that will be used to characterize spatial and temporal changes in the provenance of Izu-Bonin forearc sediments recovered during Ocean Drilling Program Leg 125. These data document the history of the Izu-Bonin arc system as reflected in the framework mineralogy of supra-subduction zone sediments. Subsequent analysis will reveal the record of arc-splitting events as well as the spatial and temporal episodes in forearc volcanism, in source type, and in source...
