ACKNOWLEDGMENTS

We thank Captain Ed Oonk and the crew of JOIDES Resolution for a very successful cruise. Henry Dick and James Natland provided an excellent working environment on the ship, allowing the shipboard party to log and sample a tremendous volume of core. Jay Miller, ODP Science Representative, and Henry Dick assisted with the manuscript editing and revision. Mr. Xu-Feng Hu, Dalhousie University, carried out most of microprobe analyses and assisted with preparation of the illustrations. Dr. D. Rhede, GeoForschungsZentrum, kindly produced the chemical maps, and Dr. K. Hahne, GeoForschungsZentrum, prepared the vein samples for chemical analysis.

This research used samples and/or data provided by the Ocean Drilling Program (ODP). ODP is sponsored by the U.S. National Science Foundation (NSF) and participating countries under management of Joint Oceanographic Institutions (JOI), Inc. Funding for this research was provided by the GeoForschungsZentrum and the Natural Sciences and Engineering Research Council of Canada.
