Summary:
The Mountain Creek Formation of the Pine Mountain Group is here named for exposures of interbedded pelitic schist and graywacke in the valley of Mountain Creek, Harris Co., GA., in the Pine Mountain anticlinorium in the Bill Arp thrust sheet. It comprises the upper unit of the Manchester Schist as originally defined by Crickmay (1935), and is lithologically identical to the Bill Arp Formation in the Great Smoky Group. It overlies the Manchester Schist and underlies the Chewacla Marble of the Pine Mountain Group. Age is Late Proterozoic.
