12PK Oolitic Limestone, Sedimentary Rock Specimens - Approx. 1" - Geologist Selected & Hand Processed - Great for Science Classrooms - Class Pack - Eisco Labs
OOLITIC LIMESTONE Oolitic limestone is a carbonate rock formed from the cementation of thousands of ooids. Ooids are tiny nodules formed from the accumulation of carbonate material around a nucleus. When cemented together and lithified, these ooids can form rock.. GREAT FOR GEOLOGY CLASSROOMS Oolitic limestone forms in reef or lagoon environments, and is useful in the classroom for lessons on depositional facies, sedimentary rocks, and stratigraphy. This set of six samples is excellent for group study and examination. GEOLOGIST SELECTED Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features. LOCALLY PROCESSED Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY. LABELED PACKAGING Samples are packaged in a transparent bag, labeled barcoded for easy identification.
6PK Raw Gray Limestone, Sedimentary Rock Specimens - Approx. 1" - Geologist Selected & Hand Processed - Great for Science Classrooms - Class Pack - Eisco Labs
GRAY LIMESTONE The massive, gray variety of limestone is often found deposited in marine environments. It is made up of organic material, primarily calcium carbonate. GREAT FOR GEOLOGY CLASSROOMS Excellent for demonstrating the tendency of calcium carbonate to effervesce in acid, and is perfect for identification and classification exercises. This set of six samples is excellent for group study and examination. GEOLOGIST SELECTED Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features.

6PK Raw Red Sandstone, Sedimentary Rock Specimen - Approx. 1"- Geologist Selected & Hand Processed - Great for Science Classrooms - Eisco Labs
RED SANDSTONE 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 red 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 physical expression of chemical differences. This set of six samples is excellent for group study and examination.
