Your cart is empty. Oolitic Limestone Specimen
Set of 6 Samples, 1"
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. Oolitic limestone forms in reef or lagoon environments, and is useful in the classroom for lessons on depositional facies, sedimentary rocks, and stratigraphy.
While each specimen will vary slightly in shape, size and color, it will measure approximately 1" in length. Specimens are packaged, labeled & barcoded for easy identification and storage.
Selected & Processed by a Geologist.
Each and every specimen is selected and hand processed by an actual geologist, ensuring that each sample exhibits defining features. Rocks and minerals are sourced from a variety of locations around the world and are processed by hand in Victor, NY.

I purchased this to enhance my triops' aquarium, and they've been fantastic! The hand-processed quality and unique oolithic texture make them visually appealing and a great addition to the habitat. The rocks are the perfect size for small tanks, and my Triops enjoy exploring them while it also helps maintain the pH of the water. Highly recommended for aquarium enthusiasts and educators!

I used these for an experiment, but they came in such small pieces. They looked a bit broken and had lots of dust and pieces in the pack when they arrived.

I love demonstrating for students how acid dissolves limestone. It felt like a lot of money for six little pieces of limestone (to someone who used to live where every streambed was full of limestone pebbles!) -- but each stone can be used more than once, as there's no need to let it sit in the vinegar until it disappears, so there's that.I still want to ask a friend in Indiana to just send me a bag of rocks for the price of postage.
