Ocoee Group Metaconglomerate

This is an image of an Ocoee Group metaconglomerate in the Blue Ridge province of the Southern Appalachians, and specifically from near Carter Lake in Georgia. Features that you can note are examples of flattened quartz lithic clasts that help define a planar fabric (foliation) in the rock, dark lithic clasts of a different composition that are also deformed, and a quartz vein that is discordant to the planar fabric.

Some questions that might arise from this image include the following. Can you tell whether the quartz vein formed before, during or after the clasts were deformed and the planar fabric formed? How much have the conglomerate clasts been flattened? Under what pressure and temperature conditions did the deformation occur?
