Accretionary prisms are one of the major components of                     convergent plate orogens, forming the pliant leading edge of the                overriding crustal plate.  The Shimanto accretionary complex in                 southwest Japan has received recent study because portions are                  well-exposed so that detailed structural and stratigraphic                      relation-ships can be investigated.  Results of that study have                 revealed t hat parts of this accretionary prism are a typical of                simple accretion at convergent plate margins.  The structural                   anomalies include a 180o reversal in structural polarity between                Eocene and Miocene accreted packets and late stage oroclinal                    flexing. This renewal will test the hypothesis that these                       anomalies are attributable to a Miocene episode of spreading-ridge              subduction, by a program of computer modeling and further analysis              of existing data.  Results are expected to clarify the                          significance of the Shimanto deformational data and explore the                 role of subduction of actively spreading ridges in accretionary                 complexes.
