MORPHOLOGICAL NOTES ABOUT AMAZONITE [PDF]
Минералогия, 2018 Morphological features of amazonite cause some onthogenic models of K-feldspars. The crystals of amazonite are zonal and sectorial. «Microcline lattice» of stresses in K-feldspar is formed after its growth during polymorphic transformation of monoclinic ...

Archaeometry, EarlyView.Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

A Newly Discovered Tablet‐Making Facility in Nineveh: Insights From Scientific Analysis
Archaeometry, EarlyView.ABSTRACT This paper addresses the question of tablet technology in the Neo‐Assyrian capital city of Nineveh. Recent excavations in the lower town of Nineveh by the Iraqi–Italian Archaeological Expedition uncovered an exceptional assemblage of more than 200 tablets from an elite residence that appears to have included a scriptorium.

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.

Archaeometry, EarlyView.ABSTRACT This study presents a systematically integrated, multiproxy characterisation of Iron Age ceramics from Tyre (Lebanon). Ninety‐nine ceramic samples from stratified Iron Age contexts on Tyre's Acropolis, together with a small Late Bronze Age and raw‐clay reference set, were analysed using petrography, microfossil identification, X‐ray ...

A thermodynamic model of the hydrolysis of microcline in acid sulfate solutions [PDF]
, 1976 A theoretical model of the hydrolysis of microcline by a hydrothermal solution has been determined for a closed system at constant temperature. Hypothetical solution compositions and temperatures were chosen to match the known geothermal system at ...

Potassium chloride recovery from mechanically activated microcline through the chlorination roasting and leaching route [PDF]
, 2023 In this study, effects of mechanical activation in the chlorination roasting and water leaching route known as CaCl2 process and developed for the production of potassium chloride (KCl) from potassium feldspar ores were studied. A microcline containing K-
