“Through hard work,as well as generous donations, the museum has assembled an extensive collection of minerals, mining equipment and fossils. These collections are open for public exhibition at the museum as well as being integrated into the education curriculum compiled for students.The mineral collection is the finest display of minerals in the State of New Jersey. Special exhibits include pegmatite minerals, the minerals of China, Russia, and Africa, and displays of individual mineral species such as quartz, fluorite, calcite, stibnite, barite, celestine, and copper. In the fluorescent mineral display you will see minerals glowing brilliantly in the dark in rich shades or red, green, orange, yellow, and blue, often in combinations of two to five fluorescent minerals in the same specimen. Hundreds of items used in mining and milling operations are on display in the Zobel Exhibit Hall. Here you will find dynamite detonators, rock drills, compressors, jaw crushers, ore cars, sinking buckets, and a wide variety of hand tools used in the mines, plus equipment used in related facilities such as laboratories and blacksmith shops. Five large display cases highlight the evolution of mine lighting and show candlepicks, oil lamps, carbide lamps, and electric cap lamps.The fossil collection includes dinosaur eggs, dinosaur bones, petrified wood, a full-size replica Tyrannosaurus Rex skull, and a large slab of siltstone showing embedded dinosaur footprints.”
