SIU to hold rock and mineral clinic at Marion event
CARBONDALE, Ill. – Southern Illinois University Carbondale’s geology program will host a rock and mineral clinic during a local gathering for mineral enthusiasts.
The clinic, set for 10 a.m. to 5 p.m. Saturday, is part of this weekend’s Marion Gem & Mineral Show at The Pavilion, 1602 Sioux Drive, Marion. Members of the public are invited to bring in any rock, mineral or geological sample for identification. They also can learn the basic common examination techniques and SIU’s geology program from Daniel Hummer, associate professor of geology, who will be on hand for the clinic, along with members of the SIU Geology Club.
“One thing I notice every time I talk to the public is that everyone has a rock story,” Hummer said. “Rocks and minerals just seem to be universally admired, and I encourage people to appreciate them and learn where they come from and how they can be identified.”
Marion Gem & Mineral Show celebrates Geologists Day, which fell on April 6 this year. Originally established in April 1966 by scientists in the former Soviet Union, the day honors and recognizes the work of geologists, geophysicists and geochemists, who study the history of Earth and the composition of rocks, soil, water, minerals and other materials.
All ages are welcome at the event, which is $2 for adults and free for students 18 and younger. Free parking will be available.
