Abstract | Preliminary results indicate that the structure of the area is dominated by two phases of regional folding that produce mushroom-type interference patterns. The Sleepy Dragon Complex is such a
regional-scale interference structure. Its geometry and timing of formation contradict the hypothesis that the complex represents a core complex. They also cast doubt on previous kinematic studies. F2 folding was a response to dextral transpression
during which both the Defeat Suite and Prosperous Suite granitoids were emplaced. Regional low-pressure metamorphism is largely late-D2 and associated with granitoid emplacement. Following F2 folding, D2 dextral transpression became localized in
discrete dextral shear zones that record retrograde metamorphism. |
