Supplementary materials provided in the Leg 185 Initial Reports Volume include: (1) communal samples plates and tables, and (2) descriptions of igneous mineralogy.

1. Communal samples plates and tables.
During Leg 185 a representative suite of rock samples were taken within each geochemical unit to represent the major lithologies in the cores: massive flows, pillowed or sheet flows, interflow material, and breccia; and also the different alteration types: veins, halos, and pervasively altered basalt (see “Communal and Composite Basement Samples for Geochemical Studies,” in the “Leg 185 Summary” chapter, and “Preparation of Composites,” p.25, in the “Explanatory Notes” chapter). Communal samples were also taken from sediments recovered at Site 1149 (see “Communal Sediment Samples,” in the “Leg 185 Summary” chapter, and “Preparation of Composites,” in the “Explanatory Notes” chapter). Basement and sediment plates show digital images of the core intervals from which the communal samples were taken. Communal samples tables contain information about sample number (i.e., core interval), type of lithology, alteration type when pertinent, and sample weight (g) for the basement samples.

2. Igneous mineralogy tables.

Tables describing igneous mineralogy from samples collected at Sites 801 and 1149.
