Conrad Duprez was Rotarian of the Day and introduce Dr. Charles Gilbert as our guest speaker. Gilbert is geology and geophysics Professsor Emeritous at OU. His presentation was What's Beneath Your Feet in Chickasha?
He said the bedrock at the surface near Chickasha is 275-270 million years old. If we would go straight from the surface we would pass through about five miles of sedimentary rock, which gets older and we go down farther, reaching rocks about 500 million years old at the bottom of this section, called the "basement."
The top of the basement is an eroded, one-exposed surface where the rocks are about 1400 million years old. Many of he basement rocks are granite, Gilber said. It would take about 25 to 30 more miles, going straight down, to move through the Earth's crust.
That would put us in the mantle, where magmas and diamonds are formed. The mantle is also where lava originates and pours out on the surface from volcanoes.
Another 3900 miles straight down would get us through the mantle and the outer core to the Earth's center.
That, friends, is what is beneath our feet in Chickasha.
The meeting adjourned after recitation of the Rotary 4-Way test.
