Mineral, Rock, and Fossil Identification
Geologists at the Iowa Geological Survey regularly identify rocks, minerals, and fossils that are brought into our office. If you are not able to stop by our office, please send photos of the specimen via email. Please make sure that the photos capture all aspects of the specimen, are in focus, and include a common object for scale (i.e., ruler, quarter, pen, etc.). Include a brief description of where the specimen was found. You can also mail specimens to the IGS for identification, and returned if requested. Visit our “Ask a Geologist” page for more information.
