Rethinking microtidal systems: Tidal signatures in the fluvial deposits of the Po River, Italy

Sedimentology, EarlyView.
ABSTRACT In microtidally influenced rivers, tides are generally assumed to leave virtually no signatures in the sedimentary record. However, this hypothesis has been surprisingly poorly tested using modern river analogues, which provide an opportunity to assess whether sedimentary signatures of microtidal regimes can develop in rivers that lack ...

Conditions and timing for the precipitation of early marine diagenetic dolomite in the Triassic Dolomia Principale (northern Italy)

Sedimentology, EarlyView.
ABSTRACT Thermodynamic constraints and empirical evidence often suggest that fabric‐retentive replacement dolomites are stable carbonate minerals that preserve ancient seawater properties. This study evaluates this hypothesis by examining the Upper Triassic Dolomia Principale in Northern Italy.

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 ...

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.
