This research used samples 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 a grant from the Australian Office for the Ocean Drilling Program. The author is grateful for the reviews of Dr. Kathleen Marsaglia and Dr. Wonn Soh and editorial input from Dr. Asahiko Taira and Lorri Peters. Dr. Kathleen Marsaglia made many helpful suggestions, particularly in regard to sandstone nomenclature. The author remains entirely responsible for any deficiencies in the manuscript. At the University of Wollongong, Dave Carrie skillfully made many thin sections and provided other technical assistance. Thin sections were stained at Macquarie University (arranged by Dr. Norm Pearson). Peter Johnson drafted the figures.
