Red Sandstone Specimen, Red Sandstone Specimen is made up of well-sorted and well-rounded grains of quartz., Pack of 12

Details

Here is the corrected text: • Red Sandstone: This sandstone is composed of well-sorted and well-rounded grains of quartz, indicating that the clasts in the rocks have traveled a long distance from their source and were heavily eroded along the way. The red coloration is due to the inclusion of iron in the chemical structure of the rock. • Great for Geology Classrooms: Ideal for students to compare with white sandstone to understand the physical expression of chemical differences. This set of twelve samples is excellent for group study and examination. • Geologist Selected: Each specimen is selected and hand-processed by an actual geologist, ensuring that each sample exhibits defining features. • Locally Processed: Our rock and mineral samples are sourced from a variety of locations around the world and processed in Victor, NY. • Individually Packaged & Labeled: Each specimen sample is packaged in a transparent bag and labeled with a barcode for easy identification.
