INDEX TO VOLUME 112

This index provides coverage for both the Initial Reports and Scientific Results portions of Volume 112 of the Proceedings of the Ocean Drilling Program. Index entries with the suffix a refer to pages in the Initial Reports, and those with b, to pages in the Scientific Results (this book). The index is presented in three parts: (1) a Subject Index, (2) a Site Index, and (3) a Paleontological Index. In addition to this printed version, the index is also available in the form of a machine-readable, ASCII-encoded, 9-track magnetic tape, 1600 bpi. The index was prepared by Wm. J. Richardson Associates, Inc., under subcontract to the Ocean Drilling Program. It follows the concept developed by the Deep Sea Drilling Project at Scripps Institution of Oceanography for a comprehensive, cumu- lative index of DSDP volumes. Both of these indexes are based on a hierarchy of entries: (1) a main entry, defined as a key word or concept followed by a reference to the page on which that word or concept appears; (2) a subentry, defined as a further elaboration on the main entry followed by a page reference; and (3) a sub-subentry, defined as an even further elaboration on the main entry or subentry followed by a page reference. The Subject Index follows a standard format. Geographic and individual names are referenced in the index only if they are subjects of discussion. This index also includes broad fossil groups, such as foraminifers and radiolarians, which also appear in the Paleontological Index. The Site Index is structured to contain entries for the sites discussed in the volume. Site entries are modified by subject subentries. The Paleontological Index is an index relating to significant findings and/or substantive discussions, not of species names per se. This index covers three varieties of information: (1) broad fossil groups, including individual genera and species that have been erected or emended formally; (2) biostratigraphic zones; and (3) fossils depicted in illustrations. The indexes cover text figures and tables but not core description forms (“barrel sheets”) or core photographs. Also excluded are bibliographic references, names of individuals, and routine front and back matter.
