Visual core description

Visual core description is done on the archive half after non-destructive physical properties, color reflectance, linescan images have been carried out.

SMEAR SLIDE/THIN SECTION DESCRIPTION
Smear slides of unconsolidated material and thin sections of "hard rocks" are prepared to document the lithology of recovered material and to aid in core description. Primarily, they are made from all representative lithologies, and also from special or unique layers of particular interest. Thus, the number of smear slides (or thin sections) produced is a function of the homogeneity of the sedimentary section.

Visual Core Descriptions (VCDs) are entered into the Drilling Information System (DIS) using the "section unit input form":
