Drowned carbonate‐rimmed margin controlling shelf‐edge delta progradation and sedimentation dynamics: Upper Cretaceous Woodbine Formation, Texas, USA

Sedimentology, EarlyView.
ABSTRACT Shelf‐edge deltas are commonly interpreted to record basinward facies migration across uninterrupted, gently dipping shelf margins; however, examples from mixed siliciclastic‐carbonate margins reveal more complex depositional dynamics. Periods and areas of carbonate sedimentation within mixed siliciclastic‐carbonate margins can modify shelf ...

Salt Range Formation of Pakistan Preserves Unique Record of Volcanic Fertilization During the Ediacaran Shuram Excursion

Terra Nova, EarlyView.
ABSTRACT Thin, discontinuous, organic‐rich oil shale beds in the siliciclastic‐evaporitic Salt Range Formation (SRF) of Pakistan are of approximate Neoproterozoic to Cambrian age based on stratigraphic constraints. The beds are enriched (26–43 wt.% total organic carbon, TOC) in aliphatic organic matter (OM) of low thermal maturity despite their ...

Recent Advances in Boron Removal From Geothermal Waters: A Review

Water and Environment Journal, EarlyView.
This review provides a comprehensive overview of boron removal technologies from geothermal fluids and highlights the limitations of conventional treatment methods. Ion exchange, hybrid processes and membrane filtration are identified as the most dominant approaches in recent studies.

Differentiation and Population Structure of Idyla bicristata (Gastropoda: Clausiliidae) on Euboea, Greece

Zoologica Scripta, EarlyView.
ABSTRACT Idyla bicristata is a highly variable rock‐dwelling door snail species living on limestone rocks around the Aegean Sea. The island of Euboea and the adjacent Greek mainland are a hotspot for morphological variability in I. bicristata, resulting in the various forms being named. A population genetic analysis of 23 populations of I.
