Neural Networks and Multivariate Analysis Based on Geochemical Data to Determine Stone Provenance From Ancient Calabrian Quarries (Southern Italy)

Archaeometry, EarlyView.
ABSTRACT This study shows an innovative approach to determine the origin of some Calabrian rocks quarried used in ancient times. Twenty‐five quarries, distributed in all the Calabrian provinces (Southern Italy), were studied and sampled. Ten samples were taken from each quarry, for a total of 250 samples.

Materials Characterization and Technological Aspects of Hellenistic Grey Ware Lamps From Nysa‐Scythopolis (Israel): Evidence Suggesting Local Production?

Archaeometry, EarlyView.
ABSTRACT Grey ware lamp fragments and a production waster from Tell Iẓṭabba (Israel) were analyzed to determine their manufacturing technology and provenance. These were compared with a light brown‐orange reference fabric from the same site.

Ab initio calculations of elastic constants of plagioclase feldspars [PDF]

, 2014
Plagioclase feldspars comprise a large portion of the Earth's crust and are very anisotropic, making accurate knowledge of their elastic properties important for understanding the crust's anisotropic seismic signature.

an experimental Study of the Growth of Feldspars in Sediments.

, 1961
The purpose of the present work is to investigate the growth of authigenic feldspars in sediments, more specifically in shales. Authigenic feldspars have been discussed frequently in the literature, but most of these discussions have been descriptive ...

Hidden in the Glaze: Cobalt Blue Decorations of Catalan Tin‐Glazed Ceramics From the 16th to 18th Centuries

Archaeometry, EarlyView.
ABSTRACT This study investigates technological evolution in 16th–18th century Catalan tin glazes and cobalt blue decorations. Analysis reveals three glaze strategies, highlighting shifts in tin oxide use and cobalt pigment composition. In the 16th century, tin oxide acted as an opacifier and cobalt pigments exhibit low arsenic content with CoO/NiO and ...

Incidence of Alkali Release in Concrete Dams. Evaluation of Alkalis Releasable by Feldspars

MATEC Web of Conferences, 2018
Alkali release from aggregates can constitute a source of alkalis in concrete exposed to wet environments for long periods of time. Feldspars are one of the minerals that can release alkalis to the concrete with time.
