Investigation by pXRF of Caltagirone Pottery Samples Produced in Laboratory

Open Archaeology, 2017
In the study of archaeological ceramics, it is important to have compositional data to identify their origin and source. The fabric also provides useful information on the production technology, especially with regard to the firing steps.

Surface ages of alluvial fans in the southern Central Andes recorded by ground‐ and space‐based hyperspectral reflectance

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Secondary weathering of alluvial‐fan surfaces records the relative, and even absolute, ages of deposited sediments up to 300 ka. Hyperspectral imagery quantifies evolving mineral‐weathering pathways to unlock high‐resolution mapping and dating of these sedimentary landscapes.

7000 Years of Aboriginal Mining at Sugarloaf Hill in the Riverland Region of South Australia

Archaeology in Oceania, Volume 61, Issue 2, Page 277-311, July 2026.
ABSTRACT Silcrete and chert are commonly represented in Aboriginal archaeological lithic assemblages across large parts of the southwestern Murray‐Darling Basin (MDB). In South Australia (SA), these materials were sourced from a series of quarries located along the incised course of the Murray River through the upper Riverland region.

Poseidon's Sanctuary at Samikon—The Discovery of an Ancient Temple Through an Integrated Geophysical and Geoarchaeological Survey Approach for Lagoonal and Swampy Environments

Archaeological Prospection, Volume 33, Issue 3, Page 745-758, July/September 2026.
ABSTRACT Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and ...
