Chalk Limestone Specimen (Sedimentary Rock), Each

Details

Here is the corrected text: Limestone Chalk Specimen: Limestone is primarily composed of organic material, mainly calcium carbonate. The chalk variety consists of the shells of coccolithophores, small platy animals that stack together and powder easily. Large layers of chalk indicate a low-oxygen environment, likely ancient seafloor beds. Ideal for geology classrooms, this specimen provides an excellent example of chemically formed sedimentary rock and is suitable for identification and classification exercises. It can also be used to teach students about rounding and sorting. Each specimen measures approximately 1 inch in length and will vary slightly in shape, size, and color. Every sample is individually packaged, labeled, and barcoded for easy identification and storage. Selected and processed by an actual geologist, each specimen exhibits defining features. Our rock and mineral samples are sourced from various locations worldwide and are hand-processed in Victor, NY.
