...Thomas E. West, Jr.; Donald T. Secor, Jr.; John R. Pray; Irene B. Boland; Harmon D. Maher, Jr. Abstract Detailed field mapping at the east end of the Pine Mountain terrane in central Georgia indicates that the Box Ankle fault is an ∼4-km-thick ductile shear zone separating Grenvillian basement...

...Robert J. Hooper; Robert D. Hatcher, Jr. Abstract The Pine Mountain terrane is exposed in a complex window within the Piedmont of Georgia and Alabama. The eastern end of the terrane is framed by three ductile faults of demonstrably different ages. The polydeformed pre-thermal peak Box Ankle fault...

... the window, were subsequently arched into a gently east-plunging antiform (Fig. 1B) . The window is framed by three major faults—the Towaliga fault to the north, the Box Ankle fault to the east, and the Goat Rock–Bartletts Ferry fault system to the south—which have distinctly different relative ages...

.... A lowside syncline or monoclinal ankle (“half syncline” or upturn) is present at the base of the block, and a highside rollover or monoclinal knee (“half anticline”) develops above the upthrown edge of the block. The fault may ultimately offset the limb connecting the fold pair, and because of its...

... of this block depends on seal by the fault on the southwest (closure indicated by asterisk). Transverse closure along the downthrown edge of the center block (indicated by two “X”s), in contrast, would mostly depend on the upturned limb or ankle of a block-edge flexure. Where a high side rollover is present...
