Oolitic Limestone, Sedimentary Rock Specimen - Approx. 1" - Geologist Selected & Hand Processed - Great for Science Classrooms - Eisco Labs

This oolitic limestone specimen is a sedimentary carbonate rock formed from the cementation of thousands of ooids — tiny nodules built up around a nucleus by accumulated carbonate material. It forms in reef or lagoon environments and is valuable for classroom discussions of carbonate chemistry, ancient marine settings, and diagenesis. Each specimen measures approximately 1 inch, is geologist-selected and hand-processed, and arrives in individual packaging. Suitable for geology identification and classification exercises.
