Deducing Deformation from Quartz Crystallographic Preferred Orientation Data part of Cutting Edge:Courses:Structural Geology and Tectonics:2022 Structure and Tectonics Forum:Abstracts
This abstract page from the On the Cutting Edge professional development program presents a novel maximum likelihood method for inferring deformation history from quartz crystallographic preferred orientation (CPO) data, leveraging Taylor-Bishop-Hill theory and multivariate normal distribution assumptions to minimize reliance on macroscopic kinematic constraints.

How Do Geologic Data Constrain Shear Zone Models, Really? part of 2018 Structure and Tectonics Forum:Abstracts
This abstract page from the 2018 Structure and Tectonics Forum presents a Bayesian statistical framework for quantifying uncertainty in shear zone models using geologic data such as foliation, lineation, and magnetic susceptibility, demonstrating how data types constrain kinematic and dynamic parameters through Markov chain Monte Carlo simulation.
