Paleostress inversion
WebNov 21, 2014 · Paleostress inversion provides an analysis of fault orientation and kinematic indicators to infer principle paleostresses (Carey and Burinier 1974; Etchecopar et al. 1981; Angelier 1990, 1994). The result of the analysis contains information of the stress conditions that were responsible for brittle deformation events. All methods for ... WebMay 28, 2024 · Paleostress tensors provide a dynamic interpretation (in terms of stress orientation) to the kinematic (movement) analysis of brittle features. ... Inverse methods Stress inversion uses fault data measured at outcrop to infer the remote, paleostress tensor that produced or reactivated the striations and planes observed. The challenge is ...
