Correlating tephras and cryptotephras using glass compositional analyses and numerical and statistical methods: review and evaluation
We define tephras and cryptotephras and their components (mainly ash-sized particles of
glass±crystals in distal deposits) and summarize the basis of tephrochronology as a …

Phase transformations during fluidized bed reduction of New Zealand titanomagnetite ironsand in hydrogen gas
Direct reduction of iron ore in a fluidized bed reactor is usually limited by the onset of particle
sticking at temperatures≳ 800° C. This paper examines the phase and microstructural …

Wave impacts on coastal cliffs: do bigger waves drive greater ground motion?
CF Thompson, AP Young… - Earth Surface Processes …, 2019 - Wiley Online Library
Coastal cliff erosion is caused by a combination of marine forcing and sub‐aerial processes,
but linking cliff erosion to the environmental drivers remains challenging. One key …

Seismic signatures of individual wave impacts on a coastal cliff
CF Thompson, ME Dickson… - Earth Surface Processes …, 2022 - Wiley Online Library
The mechanisms through which wave action induces cliff erosion are not well quantified,
which limits our ability to model future cliff erosion. Previous studies have investigated using …

Sticking-free reduction of titanomagnetite ironsand in a fluidized bed reactor
Fluidized bed reduction of iron ore fines is typically inhibited by the onset of “sticking” at
temperatures above 973 K, which leads to particle agglomeration and defluidization of the …
