The Tate quadrangle occupies an area in northwestern Georgia. The principal industry of the area is the quarrying and finishing of marble. Georgia is the second largest producer of marble in the U. S. Most of Georgia's marble comes from the small area in the neighborhood of Tate and Marble Hill. The original layers that resulted in the formation of this marble were sedimentary limestone. Marble is a metamorphic rock, not sedimentary. How was the marble eventually formed?
