Product Overview
The large clasts in conglomerate indicate that the pieces of rock underwent a large amount of rolling, bouncing, and other weathering to become round. This implies deposition in a river far from the source of the clasts. Ideal for teaching students about rounding and sorting, as well as for identification & classification exercises. While each specimen will vary slightly in shape, size and color, it will measure approximately 3" in length. Each is individually packaged, labeled & barcoded for easy identification and storage.
