Date: Wednesday, August 17, 2022
Social Time: 7:00 pm
Meeting Time: 7:30 pm
Topic: "Radioactive Age Dating
Location: In-person and via Zoom Link here and on the GMS Calendar here when available

The July meeting discussed Banded Iron Formations, a relic of the early Earth’s atmosphere and the beginning of oxygen-producing life. They are responsible for most of the commercially produced iron mined in the world.

The August meeting will discuss radioactive age dating, one of the primary means for determining the age of the Earth, and one of the most misunderstood. Several procedures will be described, including their range and limitations and how radioactive age dating is calibrated with other methods. Although concentrations of radioactive minerals are not common, radioactive isotopes of common elements are present in many minerals and measurement techniques are sensitive enough to derive valuable dating information.

The August meeting will be held on the third Wednesday of the month, the 17th and will start at 7:30 pm, with the social and troubleshooting half hour starting in Zoom at 7:00 pm. The meeting link will be sent out early in the month.
