The metamorphosed belt consists of two parts, the Highland-Blue Ridge anticlinorium, which is a part of the Appalachian Mountains, and an area of overthrust rocks, the Martic thrust-block, which lies southeast of the anticlinorium and was brought to its present position by thrust-faulting.The rocks of the metamorphosed belt are closely folded, and are broken by thrust-faults that show all gradations from broken, recumbent anticlines to clean-cut thrusts developed from them. The Martic overthrust is a low-angled thrust of the Scottish Highland type, which has carried the southeastern part of the Appalachians over the Paleozoic limestones . . . This content is PDF only.
