Core descriptions

Visual core descriptions (VCDs), smear slide data tables, thin sections, chert/porcellanite and lithology logs, and digital images are included in this section. VCDs, smear slides, and thin sections are combined into a single PDF file for each site. The entire set of core images in PDF are available in the IMAGES directory.
