Greek Commodities in Phoenicia: An Interdisciplinary Study of Imported Amphorae From Tell el‐Burak (Lebanon)

open access: yesArchaeometry, EarlyView.
ABSTRACT This paper examines transport amphorae of Greek/Aegean types from the 7th–4th c. BCE imported to the Phoenician coastal settlement of Tell el‐Burak, Lebanon. We present a selection of 58 pieces analyzed by typological, chemical (NAA), and petrographic approaches.

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

open access: yesArchaeometry, 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 ...

Testing the impact of diagenesis on the delta O-18 and delta C-13 of benthic foraminiferal calcite from a sediment burial depth transect in the equatorial Pacific [PDF]

open access: yes, 2013
Stable oxygen and carbon isotope (δ18O and δ13C) values measured in foraminiferal calcite are one of the primary tools used in paleoceanography. Diagenetic recrystallisation of foraminiferal calcite can act to reset primary isotopic values but its ...

Coastal evolution, environmental change and carbon storage in the Thung Prong Thong Mangrove, eastern Gulf of Thailand

open access: yesBoreas, EarlyView.
Palaeoenvironmental records along the eastern coast of Thailand remain sparse, with only a few studies attempting to reconstruct past climatic and environmental conditions. However, additional palaeoenvironmental, palaeoclimatic and sea‐level records are needed to improve our understanding of coastal evolution and local environmental changes.
