The state geologist is tasked by Indiana Code 21-47-2-1(c) to collect and archive rock, mineral, soil, and other geologic samples as a state repository at Indiana University.
At present, the IGWS maintains more than 2 million objects related to Indiana geology in its collections and archives. Its holdings include drilled rock and unconsolidated core, rock chip sets, lithological strips, processed geochemical samples, coal and sediment samples, conodont microfossils, limestone and other industrial mineral specimens, and teaching-quality rocks, minerals, and fossils. Moreover, the IGWS contains vast holdings of digital data, geophysical logs, data sheets, and historic maps and photographs. The collections foster new economic opportunities, support public learning and research, and enrich the Survey's exhibits, educational activities, and public programming.
Scientists, students, and museum professionals are welcome to use IGWS collections for short- and long-term study by accessing the IGWS digital portals in the menu to the right, or by contacting the collections manager to request loans of physical material for research or exhibition.
