- Pack of 12 Arkose samples approximately 1" (3cm) in size
- Small, angular grains indicate deposition in an ephemeral river system near to the clast source
- Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements
- Great for offering a modest challenge to students during identification and depositional history exercises
- Specimen comes in clear labeled and barcoded bag for ideal storage
Arkose is a clastic sedimentary rock made up of angular, poorly-sorted sand-size grains. The large, proximal nature of the clasts in arkose make this a useful specimen for identifying the provenance and interpreting the depositional environment for the rock. Pack of 12 samples.
