At Brighton Town Hall in the downstairs meeting room, the Rochester Academy of Science will hold their Mineral Meeting.

We will have a guest speaker, Dr. Rory Cottrell, is a researcher at the University of Rochester. She will tell us about An Archeomagnetic Record from Southern Africa and its Bearing on the South Atlantic Anomaly. A dramatic decrease in the Earth's magnetic field in the past ~160 years may be linked to a low intensity geomagnetic anomaly in the south Atlantic region. Studies of magnetic minerals found in burnt grains, floor and ceramic materials from Iron Age sites in South Africa help researchers understand the phenomenon. Visitors welcome.
