Effect of Thermal Shock on Grindability of Zircon for Preparation of Zircon Flour

open access: yesHigh Temperature Materials and Processes, 2013
AbstractThis paper deals with the effect of thermal shock treatment on grindability and grinding characteristics of zircon minerals and the overall energy saving achieved. This attempt is made due to a fine dry grinding of zircon minerals to produce zircon flour is an energy intensive operation.

Comment on: 'Stonehenge revisited: A geochemical approach to interpreting the geographical source of sarsen stone #58'

open access: yesArchaeometry, EarlyView.
Abstract In a recent paper in this journal (Hancock et al. (2024) Stonehenge revisited: A geochemical approach to interpreting the geographical source of sarsen stone #58. Archaeometry https://www.doi.org/10.1111/arcm.12999), Hancock and colleagues present a reanalysis of the geochemical dataset used to identify the likely source for the majority of ...

U–Pb dating and Sm–Nd isotopic analysis of granitic rocks from the Tiris Complex : new constaints on key events in the evolution of the Reguibat Shield, Mauritania [PDF]

open access: yes, 2012
The Reguibat Shield of N Mauritania and W Algeria represents the northern exposure of the West African Craton. As with its counterpart in equatorial West Africa, the Leo Shield, it comprises a western Archaean Domain and an eastern Palaeoproterozoic ...

On Sourcing Stonehenge Sarsen Stone #58: A Response to Nash and Ciborowski's Comments

open access: yesArchaeometry, EarlyView.
ABSTRACT This is a brief response to Nash and Ciborowski's comments in 2025 on our 2024 paper, which focused on the reinterpretation of geochemical data for Stonehenge stone #58 published by Nash et al. in 2020. We address the problems they perceived in our use of absolute elemental concentrations, our selection of discriminating elements, and single ...

Machinable, high‐conductivity NaSICON through mitigation of humidity effects during solid‐state synthesis

open access: yesJournal of the American Ceramic Society, EarlyView.
Abstract The Na+ super ion conductor (NaSICON, Na1+xZr2SixP3‐xO12) is a solid electrolyte well‐known for fast, selective Na+ transport at low temperatures, uniquely enabling sodium‐based batteries. Producing high‐quality NaSICON from solid‐state methods, especially when cost‐effective, potentially hygroscopic precursors are used, is not trivial.

Confronting Episodic vs. Continuous Heat Sources in Long‐Lived Hot Orogens: Insights From Petrochronological Studies in the Nova Venecia Complex, Araçuaí Orogen (SE Brazil)

open access: yesJournal 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.
