Complex Crustal Stratification Within the Chugach Mountains, Southern Alaska
… These observational data provide constraints for kinematic modeling following results presented in Teyssier and Cruz (2004). By optimizing the fit between field data, finite strain analysis, and modeling, a complex ductile stratification of the crust is inferred. I conclude that strain was …
