Fracture pattern development has been a challenging area of research in the Earth sciences
for more than 100 years. Much has been learned about the spatial and temporal complexity …

Calcite is a common mineral precipitated within upper crustal fault zones and associated
fractures, forming veins, mineral cements and fault coatings. It has the potential to be dated …

Veins are common features in rocks and extremely useful structures to determine stress,
strain, pressure, temperature, fluid composition and fluid origin during their formation. Here …

Microtectonics deals with the interpretation of microstructures, small-scale deformation
structures in rocks that yield abundant information on the history and type of deformation and …

Bedding-parallel fibrous veins are common worldwide in sedimentary basins, especially
within strata of low permeability. The term “beef” refers to bedding-parallel veins of fibrous …

A new model accounts for crystal growth patterns and internal textures in quartz cement in
sandstone fractures, including massive sealing deposits, thin rinds or veneers that line open …

Structural diagenesis is the study of the relationships between deformation or deformational
structures and chemical changes to sediments. The alliance of structural geology and …

Deformation and hydration processes are intimately linked in the oceanic lithosphere, but
the feedbacks between them are still poorly understood, especially in ultramafic rocks where …

In the Neuquén Basin of Argentina,'beef'(bedding-parallel veins of fibrous calcite) is
widespread within Late Jurassic black mudstones. A typical vein consists of two grey inner …

The commercial exploitation of unconventional petroleum resources (eg, shale oil/gas and
tight oil/gas) has drastically changed the global energy structure within the past two …
