into igneous, sedimentary, and metamorphic rocks and arranged within these groups
according to the current classification system.
Each specimen is labeled with its exact name, age, and locality. A system-bloc sheet
is placed over the respective label to prevent scratching. The rocks are numbered
to allow for easy re-identification in the event that a specimen is misplaced.
All specimens in the collection are delivered in system-bloc collection boxes,
