A 48 m.y. history of fracture opening, temperature, and fluid pressure: Cretaceous Travis Peak Formation, East Texas basin

Modeling fracture cementation processes in calcite limestone: a phase-field study

“…The natural fracture growth due to repeated fluid pressurization events (i.e., hydrofracturing) signifies a non-continuous and episodic crack opening that might grow rapidly over human time scales. However, recent petrographic investigations of the fractured sandstone in Cretaceous Travis Peak formation (Becker et al 2010) reveal a prolonged fracture growth driven by gas generation, over a duration of 48 m.y. at the estimated crack opening rates of 16-23 μm/m.y.…”

Predicting Multi-scale Deformation and Fluid Flow Patterns in Folds Using 3D Outcrop Models and Mechanical Modelling

“…The present-day configuration of fracture networks in both subsurface reservoirs and outcrops is often the cumulative result of pre-folding, syn-folding and post-folding (exhumation) related fractures (Becker et al, 2010). Furthermore, syn-folding fracture patterns may differ strongly in different structural domains of the fold (Bergbauer & Pollard, 2004).…”

“…First, it is difficult to discern the pre-folding fractures from syn-folding fractures, as folding can also alter the pre-existing fractures by reactivating or extending them (Becker et al, 2010). Reversely, the preexisting fractures may influence the syn-folding fracture patterns, as they cause local weaknesses in the rock.…”

Remote sensing and field analysis of the Palaeozoic structural style in NW Libya: The Qarqaf arch a paleo-transfer fault zone between the Ghadamis and Murzuq basins

“…Fills in such sedimentary dykes experienced the same transformations than host layers with however perhaps more recrystallization leading to orthoquartzite in reason of easy liquid percolation through rapidly opening features, followed by long time hydraulic activity expected in deep basins (Becker et al, 2010). Sedimentary dykes are widespread in the Cambrian to late Ordovician sandstones, especially along and near fault arrays (Fig.…”
