Archaeometry, EarlyView.ABSTRACT With this contribution, an attempt is being made to chart the timeline of the invention of the European hard‐paste porcelain based on historical documents. They were evaluated to trace the development lines from Tschirnhaus's early experiments with burning mirrors and lenses in the 1680s to finding ‘wax porcelain’ around 1694 to the ...

The First Archaeomagnetic Age at Tiwanaku and Implications for Dating Andean Metallurgical Furnaces
Archaeometry, EarlyView.ABSTRACT This paper presents the first archaeomagnetic dating at Tiwanaku (Andean Altiplano). We compared the geomagnetic field values recorded by a metallurgical furnace against an updated SHAWQ2k‐SH global model and a regional intensity curve, both of which include, for the first time, high‐quality intensity data from the Southern Hemisphere.

A Clinical Study of the Distribution and Morphology of Harris Lines
Archaeometry, EarlyView.ABSTRACT Harris lines are commonly used in bioarcheology to infer lifestyle in ancient populations; however, their etiology and identification parameters are still under debate. The aim of this study is to observe the distribution of the lesions in a contemporary clinical sample to address their association with etiological factors, age, biological sex,

Quality Control Measures for Enhancing Confidence in Nanoscale IR Spectroscopy
Geostandards and Geoanalytical Research, EarlyView.Key Points Common lab materials and sample handling may introduce molecular and particulate contaminants detectable by PiFM. We present a spectral database of common contaminant signatures to support accurate nanoscale analysis. We provide practical guidelines to improve preparation, handling, and storage of samples to mitigate contamination, ensuring ...

Journal of Metamorphic Geology, EarlyView.ABSTRACT Orogenic belts that sustain elevated temperatures at intermediate crustal depths for tens of millions of years are known as hot orogens. The evolution of these hot orogens is largely influenced by thermal maturation, primarily driven by the distribution of heat‐producing elements (HPEs), such as K, Th and U in the overthickened crust.

Journal of Metamorphic Geology, EarlyView.ABSTRACT Metaophiolites and metasediments of the Piedmont Zone are exposed in the Soana Valley, a poorly studied area of the Western Alps, located between the Europe‐related Gran Paradiso massif and the Adria‐related Sesia–Lanzo zone. Previous investigations reported the occurrence of only greenschist‐facies metamorphic assemblages in the metasediments.

Field‐based evaluation of glass cullet as a supplementary sediment source for coastal restoration
Restoration Ecology, EarlyView.There is an ever‐increasing demand for sand to support projects like beach nourishment and dune restoration, but dredging and mining sand causes environmental damage. Demonstrating the environmental and ecological compatibility of crushed and ground glass known as cullet to support coastal restoration projects could simultaneously divert waste from ...

Sedimentology, EarlyView.ABSTRACT Despite high convergence velocity, the southern Ryukyu subduction has relatively low and sparse instrumental seismicity, in contrast with the Yaeyama Islands, hit by huge tsunamis over the last few thousand years. This study explores the potential of deep marine sediments to record past large earthquakes and tsunamis.

Sedimentology, EarlyView.ABSTRACT For most of Earth history, carbonate sediments deposited in shallow marine settings are the only remaining archive of changing biogeochemical cycles. All deep‐sea sediments older than >200 Ma have been subducted and are therefore lost from the record. Stable carbon isotope (δ13C) values of shallow marine carbonates are available for older time

P‐T‐t‐d Evolution of Low‐Grade Metamorphic Xenotime, Eastern Alps (Austria)
Terra Nova, EarlyView.ABSTRACT In situ LA‐ICP‐MS U‐Pb dating of xenotime was used to establish the age of low‐grade metamorphism in Permian metasediments of the Austroalpine Unit (Eastern Alps, Austria). Complexly zoned xenotime in chloritoid‐bearing metasedimentary samples possesses distinct MREE‐rich domains. In the eastern sample, this domain yielded a date of c. 135 Ma,
