Break-Up of Pangea
This specimen is a polished diabase fragment from the Central Atlantic Magmatic Province deposits of Eastern North America. Similar to the specimen in the Acrylic version of the Mini Museum, but much larger, the item is encased in an acrylic specimen jar and housed in a glass-topped riker display box measuring 4x3x1 (inches). A small information card will accompany the specimen.
The source rock was donated by the Luck Stone quarry adjacent to the Manassas U.S. Civil War battlefield in Northern Virginia. The quarry is a magnificent location where it is possible to clearly see one of the rift valleys which tore through the ancient supercontinent and might once have become the Atlantic Ocean.
