Geothermal microbial reservoirs: Staircase fractures inward microbialites in addition to travertines

Figure seven from Maggi et al.: Examples of gentle gradient deposits are shown. Scattered fractures alongside staircase geometry present prevailing extension inwards the ramps together with sliding along the lamination/layer parallel (LaP) segments.

Matteo Maggi together with colleagues from Italy together with Brazil acquaint a novel model of the evolution of fractures showing a stairway trajectory, commonly occurring inwards finely laminated rock, such microbialites together with travertines. These fractures strongly heighten permeability yesteryear connecting several highly porous zones enveloped inwards tight impermeable levels.

Understanding together with predicting this fracture blueprint geometry, distribution, together with interconnection is valuable non solely for locating H2O supplies, but likewise for oil, gas, together with geothermal exploration.

Major discoveries of hydrocarbon bring late been made inwards continental (lacustrine) microbial carbonates inwards the Brazilian South Atlantic margin, only about of which exhibit a texture similar to those unremarkably observed inwards travertines. Understanding of these lacustrine carbonates is withal at an early on stage.

Given that inwards modern rift settings, vent-related thermal (travertine) together with non-thermal (tufa) carbonates are a major component, the proposed conceptual model of staircase fracture localization contributes to the grooming of a model for the occurrence of high-permeability pathways inwards hydrocarbon together with geothermal microbial reservoirs.
