Investigating Technology and Raw Materials Source of the Archaic and Classical Architectural Terracottas From the Athenaion in Castro (Apulia, Italy)

Archaeometry, EarlyView.
ABSTRACT Since 2000, archaeological excavations have brought to light the sanctuary of Athena in Castro (Apulia, Italy), including terracotta roofs dated between the 6th and 4th centuries bce. Based on their morphological and stylistic features, it is suggested that the terracotta items were manufactured in the Greek colony of Taras (modern Taranto ...

Beachrock formation influenced by co‐seismic deformation and relative sea‐level changes during the Holocene near the Gulf of Saros, Türkiye (NE Aegean Sea)

Boreas, EarlyView.
This is the first proof of beachrock found on the nearshore of the Gulf of Saros. Beachrock generation was influenced by tectonic activity, geomorphological processes, and sedimentation. The Late Holocene beachrock deposits were altered by co‐seismic deformation.

Coesite Discovery in Eclogites Confirms UHP Metamorphism in the Orlica‐Śnieżnik Dome (SW Poland)

Journal of Metamorphic Geology, EarlyView.
ABSTRACT Eclogite lenses are exposed within the orthogneiss‐dominated core of the Orlica‐Śnieżnik Dome in the Sudetes, which forms the northeastern margin of the Bohemian Massif (Variscan Belt of Central Europe). The presence of coesite inclusions in garnet and omphacite confirms that these eclogites underwent ultrahigh‐pressure metamorphism.
