Expanding the Ichnofacies Model to Tidal Straits: Testing Predictions and Assessing Anomalies

open access: yesTerra Nova, EarlyView.
ABSTRACT Trace fossils are instrumental in facies analysis, but some depositional environments remain underexplored. Cenozoic deposits in Italy have been studied to evaluate the ichnology of tidal straits. These comprise four zones: (1) strait centre, (2) dune‐bedded strait zone, (3) strait end and (4) strait margin.

P‐T‐t‐d Evolution of Low‐Grade Metamorphic Xenotime, Eastern Alps (Austria)

open access: yesTerra Nova, EarlyView.
ABSTRACT In situ LA‐ICP‐MS U‐Pb dating of xenotime was used to establish the age of low‐grade metamorphism in Permian metasediments of the Austroalpine Unit (Eastern Alps, Austria). Complexly zoned xenotime in chloritoid‐bearing metasedimentary samples possesses distinct MREE‐rich domains. In the eastern sample, this domain yielded a date of c. 135 Ma,
