The mechanical discontinuities in the upper crust (ie, faults and related fractures) lead to the
uprising of geothermal fluids to the Earth's surface. If fluids are enriched in Ca2+ and HCO3 …

Non-marine carbonate rocks including cave, spring, stream, calcrete and lacustrine-
palustrine sediments, are susceptible to early diagenetic processes. These can profoundly …

Abstract During the Aptian (Cretaceous), in what is now the South Atlantic, the largest
chemogenic (abiotic) carbonate factory so far identified in the Phanerozoic geological record …

The study of hydrothermal travertines contributes to the understanding of the interaction
between physico‐chemical processes and microbial mats in carbonate precipitation. Three …

Branched, bush-or shrub-like crystals are some of the most striking components of
carbonate facies from the Cretaceous South Atlantic Pre-salt carbonate reservoirs. Many …

Travertine-depositing hot springs can generate various carbonate minerals with or without
the participation of microorganisms. They thus serve as good natural laboratories to study …

Linking the architecture of structural conduits with the hydrothermal fluids migrating from the
reservoir up to the surface is a key-factor in geothermal research. A contribution to this …

Abstract 3D modelling represents a powerful tool to characterize the geobody architecture of
depositional systems. Several examples have been proposed in literature both for marine …

Facies character, diagenesis, geochemical signature, porosity, permeability, and geometry
of the upper Pleistocene Tivoli travertines were investigated integrating information from six …

Earthquakes-related soft-sediment deformations (seismites) are relevant structures to help
reconstructing the palaeoseismicity in a region. Nevertheless, although seismites have been …
