“…When pore fluids become locally, at nanoscale to microscale, saturated in aragonite during ongoing calcite precipitation, aragonite dissolution may slow down or temporarily stop and a relic may become enclosed in the calcite crystal (Martín‐García et al, 2014; Martín‐Pérez et al, 2012), such as observed here. A detailed speleothem study by Martín‐García et al (2014) and observations of Holocene travertine and tufa by Rodríguez‐Berriguete (2020) further suggest that precipitation of calcite started as microcrystalline, scattered crystals between aragonite fibres. The number of calcite crystals then grows and crystals merge, a process referred to as aggrading recrystallization by Rodríguez‐Berriguete (2020).…”

“…Dendrites or dendritic textures (Jones, 2017) refer to branching, often complex, crystal aggregates. They may have a range of crystal and branching morphologies (Claes et al, 2017; Gandin & Capezzuoli, 2014; Jones, 2017; Jones & Peng, 2012; Jones & Renaut, 2008; Rodríguez‐Berriguete, 2020) that sometimes have been given specific, morphological names (dendritic fan, band and feathers; Della Porta, 2015; Gandin & Capezzuoli, 2014; Jones & Renaut, 2008).…”

“…The rapid lateral and vertical alternations and changes in facies and fabrics, at multiple scales, are causes of their heterogeneity and anisotropy in petrographic and geophysical properties (Claes et al, 2017; De Boever et al, 2016; Gagrcía‐del‐Cura et al, 2012; Soete et al, 2015). Gradually, interest in the presence and variety of diagenetic products in calcareous spring deposits increased (Arp et al, 2013; Claes et al, 2017; Gandin & Capezzuoli, 2014; Rodríguez‐Berriguete, 2020; Shiraishi et al, 2020). The processes and their products go beyond localised precipitation of cements in cavities/fractures, or dissolution by meteoric waters, resulting in enlarged voids.…”

Spring systems are efficient and fast precipitating non‐marine carbonate factories, but they are also prone to (early) diagenesis. Evidence of diagenesis in travertines remains controversial as the resulting textures have been considered primary in other deposits and the impact on geochemical/palaeo‐environmental signals is often poorly addressed. This study revisits the Y‐10 core, taken in 1967 at one of the upper terraces of Mammoth Hot Springs in Yellowstone National Park (USA). The travertine depositional facies in the upper 50 m of the core show a general distal to proximal facies trend upwards. To unravel the nature, impact and timing of early diagenesis, fabrics and geochemical signatures are also compared to modern hot spring carbonates. Secondary ion mass spectrometry and detailed microscopy proved powerful in determining the stable isotope signature of different cement generations, thereby detangling the fluid history. Diagenesis starts during spring activity, but these warm waters not only precipitate CaCO3 at the top, they also seem to have circulated through the porous spring fabrics below. It resulted in coarsening and homogenization of the primary textures through neomorphism of aragonite and calcite cementation, often resulting in new intracrystalline microporosity within the calcite crystals. Subsequent circulation of meteoric fluids led to dissolution and cementation, particularly near the top of the core. Careful interpretation of U/Th dates suggests that travertine deposition started at the beginning of the Holocene/end Pleistocene. Calculated depositional (precipitation) rates vary between 2 and 20 mm/year, assuming a constant rate between samples at different depths. Aragonite deposits are completely transformed to calcite below depths of 5–10 m, corresponding to a time span of 4,000 years. Core and petrography observations, together with dating, suggest that travertine strata below marine sandstones in the lower part of the core may relate to fault displacement after the onset of travertine deposition.

The Quaternary calcareous tufas precipitated in the Kurkur Oasis area in the southern Western Desert of Egypt were analyzed to determine their implications for the construction of environmental conditions during their formation. X-ray diffraction analysis showed that the tufas consist of low-Mg calcite, whereas macroscopic and microscopic analyses showed the presence of both allochthonous (clastic) and autochthonous components consisting predominantly of pisoliths, oncoids, intraclasts, lithoclasts, stromatolites and encrusted plant materials. These tufas form four facies associations that represent pisolitic intraclastic/lithoclastic oncoidal rudstones, phytohermal /bryophyte framestones, stromatolite-algal boundstones, and speleothem-like flowstones. These tufa associations were formed within a karstified carbonate terrain by a rainwater-fed paleospring system comprising waterfalls, slopes, dammed areas, lacustrines-paludal, and fluvial channel margin environments. Early diagenetic features are cementation, neomorphism and subaerial dissolution. Isotope-geochemical analysis indicated that the negative δ18O values (between – 13.26 and – 8.89‰ V-PDB) and the negative δ13C values (between – 3.16 and – 1.62‰ V-PDB) of the studied tufas are consistent with carbonates deposited from meteoric water in regions with much precipitation.
