The Conundrum of Using Kink Bands and Asymmetric Crenulation Cleavage to Interpret Shear Sense in Tectonic Analyses: A Case Study from the Baraboo Syncline (Wisconsin) part of Cutting Edge:Courses:Structural Geology and Tectonics:2022 Structure and Tectonics Forum:Abstracts
This abstract page from the On the Cutting Edge: Structural Geology and Tectonics 2022 Forum presents a case study analyzing kink bands and asymmetric crenulation cleavage in the Baraboo Syncline (Wisconsin), challenging conflicting interpretations of shear sense by demonstrating that down-dip-verging folds and extensional crenulation cleavage are actually flattened contractional structures formed during crustal shortening, not post-shortening extension.
