Product Review
Sandstone is made up of well-sorted and well-rounded grains of quartz. This indicates that the clasts in the rocks have traveled a long distance from their source and were heavily eroded along the way. This sample is red due to the inclusion of iron in the chemical structure of the rock. This sample is also available in packs of 12.
- Single, red sandstone sample. Approximately 1" (3cm) in size
- The color of this sample is due to oxidized iron becoming interspersed with the sand grains during lithification
- Ideal for students to compare with white sandstone to understand physical expression of chemical differences
- Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements
- Specimen comes in clear labeled and barcoded bag for ideal storage
