Talk: Geologic History of Arizona by Don Davidson
Join us for an illustrated presentation on the geologic history of the state with focus on the differences between the Basin and Range (southern) and Colorado Plateau (northern) portions. The general nature of the rock sequences in the two provinces will be discussed with special emphasis on the Grand Canyon and the greater Tucson area. Development of regional geologic structures will also be explained by geologic era, as well as coverage of geologic features unique to Arizona such as copper deposits and Kartchner caverns. There will also be a brief introduction involving rock types, geologic time and plate tectonics. The talk should be of particular interest to local hikers. Refreshments will be served.
