Numerical Modeling Of Fracturing In Non-Cylindrical Folds: Case Studies In Fracture Prediction Using Structural Restoration, John Ryan Shackleton May 2009

Numerical Modeling Of Fracturing In Non-Cylindrical Folds: Case Studies In Fracture Prediction Using Structural Restoration, John Ryan Shackleton

Open Access Dissertations

This thesis contains several distinct studies aimed at better understanding fracturing in compressional fault-cored folds. At outcrops of growth strata in the Oliana anticline in the Spanish Pyrenees, the relationship of two joint sets may reflect changing mechanical properties (i.e. via diagenesis) during the folding process. Using a Schmidt hammer, I assess the rigidity contrast between the individual units and suggest that late-stage, throughgoing joints formed in strata with conditions similar to those of the present day and that early, bed-contained joints formed when the rigidity contrast between beds was significantly greater than the present day contrast. Modeling algorithms that …
