Water pathways and ancient lakes: Flowing towards new models to unravel the past
The Depositional Record, EarlyView.Abstract Significant progress has been made in understanding lake basin evolution through climatic and tectonic changes using sedimentology, sequence stratigraphy, geochemistry, hydrology and watershed characteristics to interpret three main lake basin types: overfilled, balanced‐fill and underfilled, including fluvio‐lacustrine systems.

Three-dimensional distribution of primary melt inclusions in garnets by X-ray microtomography [PDF]
, 2018 open6X-ray computed microtomography (X-mu CT) is applied here to investigate in a non-invasive way the three-dimensional (3D) spatial distribution of primary melt and fluid inclusions in gamets from the metapeitic enclaves of El Hoyazo and from the ...

The Depositional Record, EarlyView.The article demonstrates that brine was central for the supply of Ca and B to the studied saline lake. The ion transport occurred probably by thermal springs, while contributions from surface waters cannot be excluded. However, the saturation and syndepositional precipitation of Ca borates were initiated by an arid climate through evaporation, while ...

The composition of metapelitic biotite, white mica, and chlorite: a review with implications for solid-solution models [PDF]
European Journal of MineralogyBiotite, white mica, and chlorite record petrological processes and pressure–temperature conditions. Unfortunately, their crystal chemistry is complicated and thermodynamic modelling of their phase relations is hindered by this complexity.

The pioneer work of Bernard Kübler and Martin Frey in very low-grade metamorphic terranes: paleo-geothermal potential of variation in Kübler-Index/organic matter reflectance correlations. A review [PDF]
, 2018 Low-temperature metamorphic petrology occupies the P-T field between sedimentary and metamorphic petrology. Two important pillars of low-temperature metamorphism are coal petrology and clay mineralogy.

A reactive assimilation model for regional-scale cordierite-bearing granitoids: geochemical evidence from the Late Variscan granites of the Central Iberian Zone, Spain [PDF]
, 2008 Regional scale biotite and cordierite-bearing granites (s.l.) in the Variscan of the Central Iberian Zone (CIZ) are spatially closely associated with cordierite-rich nebulites and cordierite-bearing two-mica granites, and with cordierite-rich high grade ...

Experimental metamorphic petrology
Reviews of Geophysics, 1979 Since Bowen and Tuttle's pioneering study of the system MgO‐SiO2‐H2O in 1949, advances in experimental metamorphic petrology have occurred steadily rather than in “leaps and bounds”. The number and quality of papers published during the past quadrennium, 1975–1978, attests to the health of the science.

Deep Underground Science and Engineering, EarlyView.The Fobinso granitoids are granodiorites, while the Esuajah granitoids are granites based on their mineralogical composition. The granitoids are generally enriched in LILE and LREE than HFSE, MREE, and HREE, indicating mixing with crustal sources during their evolution.
