This typical page from the Corebook shows photographs of
two sides of the sample on the left (in color in the actual Corebook) and a
geophysical log and graphic description showing 50 feet above and below the sample
on the right. The name of the rock and its code (in boxes) are at the lower left, as is
the Ferm code. The left-hand side of the page is designed for rapid comparison and
description to help workers, such as drillers. The right-hand side provides
contextual information of value to a geologist. The back of the page contains
additional details about the sample.
