Technical changes in the glaze composition of tin‐glazed sculptures by Benedetto Buglioni c. 1490–1510

open access: yesArchaeometry, EarlyView.
Abstract During the 15th and into the mid‐16th centuries, tin‐glazed terracotta sculptures were celebrated for their luminous colours, perceived durability, and technical ingenuity of the novel medium. Although in high demand, the supply of these pieces was restricted because of the secrecy of the recipes used by the pioneers of the technique on the ...

The downward directed grounds hypothesis and very large cardinals [PDF]

open access: yesarXiv, 2017
A transitive model $M$ of ZFC is called a ground if the universe $V$ is a set forcing extension of $M$. We show that the grounds of $V$ are downward set-directed. Consequently, we establish some fundamental theorems on the forcing method and the set-theoretic geology. For instance, (1) the mantle, the intersection of all grounds, must be a model of ZFC.

Geochronology and geochemistry of the intrusive rocks in Yucun Au deposit, Jiangnan Transition Belt, Eastern China: Constraints on their petrogenesis, geodynamical setting and mineralization

open access: yesSolid Earth Sciences, 2020
A large number of Au polymetallic deposits have been mined in the Jiangnan Transition Belt (JTB), Eastern China. However, the formation and genesis of these Au polymetallic deposits remain unclear.

Regional study of the Archean to Proterozoic crust at the Sudbury Neutrino Observatory (SNO+), Ontario: Predicting the geoneutrino flux

open access: yes, 2014
The SNO+ detector, a new kiloton scale liquid scintillator detector capable of recording geoneutrino events, will define the strength of the Earth radiogenic heat.

Boninite and Harzburgite from Leg 125 (Bonin-Mariana Forearc): A Case Study of Magma Genesis during the Initial Stages of Subduction [PDF]

open access: yes, 1992
Holes drilled into the volcanic and ultrabasic basement of the Izu-Ogasawara and Mariana forearc terranes during Leg 125 provide data on some of the earliest lithosphere created after the start of Eocene subduction in the Western Pacific.

Tracking Bronze Age ‘itinerant smiths’ in western Poland: insights from Nd and Sr isotope data

open access: yesArchaeometry, EarlyView.
Abstract The neodymium (Nd) isotope composition of stone casting moulds found in graves of Bronze Age ‘itinerant smiths’ in western Poland was analysed to determine the provenance of their raw materials. For the first time in archaeological research, the Nd model age (TDM)—a highly useful parameter in studying the provenance of geological materials—has

Active megadetachment beneath the western United States [PDF]

open access: yes, 2008
Geodetic data, interpreted in light of seismic imaging, seismicity, xenolith studies, and the late Quaternary geologic history of the northern Great Basin, suggest that a subcontinental-scale extensional detachment is localized near the Moho.

Drivers of glacially induced fault reactivation in the Baltic Sea sector of the Tornquist Fan

open access: yesBoreas, Volume 54, Issue 2, Page 220-245, April 2025.
We analyse the effect of Quaternary glaciations on the complex tectonic pattern of the Baltic Sea sector of the Tornquist Fan. Using 2D marine reflection seismic data we determine the strike and dip angles of more than 40 potential glacially reactivated faults and calculated the Coulomb failure stress changes (ΔCFS) over the past 200 000 years.
