“…Carbonate rocks are more susceptible to cementation and porosity loss, owing to high diagenetic reactivity at low temperature and pressure, than are siliciclastic rocks (Morad et al 2000;Morse et al 2007). Early lithification and cementation can enhance fracturing by gravitational instability in high-relief platforms (Kosa & Hunt 2005;Frost & Kerans 2009) or by a propensity to fracture from other causes such as elevated pore pressures (Conybeare & Shaw 2000;Wangen 2001). Fractures may connect isolated primary pores and vugs (Antonellini & Mollema 2000).…”

A correlation is demonstrated between the presence of crack-seal texture and power-law kinematic aperture-size (width) distributions among opening-mode fractures in rocks of dominantly carbonate mineralogy. Crack-seal opening increments (opening-displacement increment sizes or ‘gaps’) within individual fractures follow narrow normal or log-normal size distributions, suggesting that fracture widening accumulates in characteristic (usually micrometre-scale) size increments. The scale invariance in overall fracture width distributions present in some fracture sets most likely arises from grouping of these increments (localization) to form larger fractures (millimetre- to centimetre-scale widths). Such localization could be a consequence of the tendency for larger, less cemented fractures to break preferentially during subsequent deformation. Cement accumulation patterns thus provide a mechanism for positive feedback whereby large-fracture growth exceeds small-fracture growth. Using characteristically sized growth increments, a fracture growth model accurately simulates fracture arrays having power-law fracture-width distributions. Model parameters can be altered to produce characteristic-width fracture size distributions. The results have implications for how fracture porosity and permeability evolve in carbonate reservoirs.

“…Syndepositional deformation and fracture development in carbonates is increasingly recognized as an important process (Cozzi 2000;Hunt et al 2003;Underwood et al 2003;Frost & Kerans 2009Berra & Carminati 2012;McNeill & Eberli 2012). Syndepositional fracture development in carbonates has been categorized into three groups: (1) gravitationally controlled fractures; (2) antecedent-topography-controlled fractures; and (3) tectonically controlled fractures (Frost 2007;Guidry et al 2007).…”

“…The resulting deformational features have been described where early-cemented strata are deformed over rigid topographic highs such as: platform escarpments, bioherm complexes, drowned reef spines and crystalline basement highs (e.g. Frost & Kerans 2009;Boro et al 2012). Tectonically controlled syndepositional fractures are related to the local faulting and folding process and are genetically related to the local stress field.…”

Outstanding exposures of Ediacaran-aged thrombolite-stromatolite bioherms and biostromes crop out in the Nama Basin, SW Namibia. Fieldwork, dovetailed with remote sensing and a terrestrial laser scanning (LiDAR) survey, allow the fracture network of this succession to be characterized, and the relative age of fracture sets and families to be determined. The results show that the microbial carbonates were affected by intense syndepositional brittle and ductile deformation. Early brittle fracturing was favoured where early lithification of microbialites took place upon deposition. Such deposits were prone to gravitational collapse due to internal weaknesses during early lithification. Timing of syndepositional fracturing of bioherms and biostromes is demonstrated by contemporaneous microbial overgrowth over brecciated material in open-mode fractures. Ductile deformation occurs preferentially around massive thrombolite domes and columns, represented by folding of mud-dominated sediments in inter-column fill. Secondary fractures developed during the long-lived structural history of the Nama Basin, resulting in a complex fracture network of syndepositional fractures overprinted by secondary fractures. These findings have important implications for carbonate reservoir characterization in microbial reservoirs and subsurface fluid-flow estimations. The observed syndepositional fractures form due to body forces that are intrinsic to the microbial system and thus do not require an external tectonic driver.
