Bahaman patch reefs: Numerous and neglected
Abstract Phanerozoic patch reefs are extensively studied because they are abundant and are potential reservoirs for valuable fluids. In contrast, geologic studies of modern reefs have largely focused on platform margins, leaving patch reefs comparatively neglected. What conditions favour patch‐reef development?

NEW DATA ON PYROCHLORE OF ALKALI PEGMATITES AND ORE ZONES OF THE VISHNEVYE MOUNTAINS (SOUTHERN URALS) [PDF]
The minerals of the pyrochlore group are abundant in rocks of the Vishnevogorsk alkaline complex – miaskites, mica rocks, carbonatites, and their pegmatites. Several generations of pyrochlore can be found in complex pegmatite bodies.

Water pathways and ancient lakes: Flowing towards new models to unravel the past
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.

FAHLORES OF ORE FACIES OF THE YUBILEYNOE MASSIVE SULFIDE DEPOSIT (SOUTH URALS) [PDF]
The Ag-, Te-, Mn, Pb-bearing tennantite and minerals of the tennantite-tetrahedrite series are recognized in chalcopyrite-pyrite-sphalerite-talc-calcite smoker chimneys, bornite- and chalcopyrite-rich and quartz-carbonate-hematite diagenites and ...

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 ...
