Metamorphic Rocks

These are the rocks formed by heat and pressure that I will take to China. They have a mass of 2.7 kg. Clockwise from upper left are schist, gneiss, marble, slate, and quartzite. The slate comes from the roof of Dave and Kim fyock's barn in Evans City, Pennsylvania. I also found coal and fossiliferous limestone on the farm. Thanks Dave and Kim!
