Towards stochastic modelling of folds in poly-deformed terranes from structural data

We present a data-driven parametric approach for modelling folds in poly-deformed terranes using an implicit scheme honouring structural geology concepts. Our method allows for more structural elements (e.g. foliations and lineations) and overprinting relationships to be incorporated into the modelling process. The geometry of folds are defined by structural parameters, which are obtained using geostatistical processes for each fold generation. We propose using this fold modelling method with a stochastic approach. Structural uncertainties are evaluated by varying interpolator parameters to generate a series of possible structural models. Variability between models is quantified using local statistical methods that highlight areas of the models which are most variable. A suite of possible models incorporating structural concepts are produced to sample the structural uncertainty.
