(Table T1) Petrographic features of sediments from footwall ODP Holes 180-1114A and 180-1116A@en

Sediment depth is given in mbsf. Lithic fragments: gabbro includes olivine gabbro, oxide gabbro, and diorite compositions; basalt and dolerite refer to tholeiitic serial affinity; andesite includes calc-alkaline basalt andesite and andesite to quartz andesite; felsite refers to dacite and rhyolite compositions; trachyte includes lava clasts and glass with K-feldspar microliths; granophyre indicates fine-grained eutectic quartz-feldspar intergrowth; shards include ash fall tephra or prevalent glassy matrix in turbidites; volcanics include fragments of uncertain definition.
