From Graves Mt. Ga
Here is the latest donation to CFCC Geology Program.
Alvin Coleman one of our Instructors recently acquired more than 30 kilograms ofÂ iridescent hematite found on Graves Mt. Ga. The geological history of Graves Mountain is as complex as the rest of the eastern seaboard. To make a complicated hundreds of millions of years story simple and short, a super continent broke up, the pieces drifted apart creating an ocean and volcanic island chains. The pieces came back together, sweeping up the island chains along the way and forming another super continent. This super continent broke up as well and the pieces drifted away to form our present day continents and the Atlantic Ocean.
Geologists still debate the exact details but certain aspects are clear. Sometimes during the continental collisions the Graves area was subducted and subjected to heat and pressure under the earth new minerals were formed, existing minerals were altered. There were many episodes of metamorphism when the rocks were heated and sometimes fractured and secondary minerals formed and filled the fissures. As the heat and pressure varied, different minerals were formed and underwent metamorphism. Eventually the area was raised back near the surface and eroded to its current exposure.(http://www.rockhounds.com/rockshop/graves_mountain.html)
Join us for the
Third Annual Flytrap Frolic!
Saturday, April 20, 2013
The Coastal Land Trust will be hosting the third annual Flytrap Frolic on Saturday, April 20th at the Stanley Rehder Carnivorous gardens, locatedÂ behind the Alderman Elementary School , in Wilmington, NC. This free event will take place between 9:00 am and 12:00 pm and will feature family friendly activities, guest speakers, and more!
In addition the Cape Fear Community College program of geology will be bringing a Fly Trap day to thirty two Elementary School classrooms. For more information about having a program at your school, contact Dan Sheret at firstname.lastname@example.org
Welcome to the 2013 CFCC Geology blog.Â There are lots of exciting things to share.Â At the close of last term we were contacted by a landowner not far from Boone, North Carolina. He brought in some very exciting artifacts found on his property.

Things only got more exciting from there! For the last month the Geology Program has inventoried and begun to catalog hundreds ofÂ artifacts found on the property. The collection has yielded items from 12,000 years old, to items traded by the French in the 18th century. And we have only scratched the surface of what this site contains. Once the winter passes we plan a field school on site that will take a more in depth study. So far evidence suggests that a Native American culture was living there for thousands of years.

There is so much to examine.
