The shape of loess particles reviewed
An important property of loess is a tendency to collapse on loading and wetting (hydroconsolidation) which can have serious consequences worldwide for civil engineering projects. This paper describesExpand
A commentary on the shape of loess particles assuming a spatial exponential distribution for the cracks in quartz
An important property of loess is a tendency to collapse on loading and wetting (hydroconsolidation) which can have serious consequences worldwide for civil engineering projects. Randomly generatedExpand
Characterization of glacial silt and clay using automated mineralogy
Abstract Glacial erosion produces vast quantities of fine-grained sediment that has a far-reaching impact on Earth surface processes. To gain a better understanding of the production of glacial siltExpand
Identifying eolian dust in the geological record
Abstract Recognition of terrestrial dust in geological records is essential for reconstructing paleoenvironments and quantifying dust fluxes in the past. However, in contrast to eolian sands,Expand
Analysis of the climatology and transport pathways of Iraq dust storms between 1985-2013
The interest of investigating the phenomenon of dust storms comes from their direct impact on human and ecosystem health and climate global change. Despite that the majority of previousExpand
Controls on the nature of loess particles and the formation of loess deposits
Abstract The story (history) of a single loess particle can be told from the formation of the planet to the making of bricks. The modal loess particle chosen for study is a 30 μm quartz particle.Expand
Problems with collapsible soils: Particle types and inter-particle bonding
Abstract A collapsible soil is composed essentially of a packing of mineral particles and a set of interparticle bonds holding the system together. Failure requires the bond system to fail and theExpand
Glacioaeolian Processes, Sediments, and Landforms
Abstract Glacioaeolian processes, sediments, and landforms are a critical component of glacial and periglacial systems. Their forms range from extensive dune systems, cover samples, thick loessExpand
Quantitative analysis of crystal-interface frequencies in granitoids: Implications for modelling of parent-rock texture and its influence on the properties of plutoniclastic sands
Abstract Generation of sediments from crystalline rocks is the result of a complex and incompletely understood suite of processes. The time evolution of the rock-fragment assemblage in sands derivedExpand
Loess as a collapsible soil: Some basic particle packing aspects
Loess is the most important collapsible soil; possibly the only engineering soil in which real collapse occurs. A real collapse involves a diminution in volume - it would be an open metastableExpand


Phase Transformations in Solids
The transformation of one polymorph to another constitutes an important aspect of phase transformations in solids. Phase transformations in many solids are accompanied by interesting changes inExpand
An occurrence of flat-topped ripple marks [Florida]
Flat-topped ripple marks from the Pennsylvanian rocks of Oklahoma have been compared with similar ripple marks formed at low tide along the modern Florida coast. It is concluded that flat-toppedExpand
The Alkali-Feldspar Join in the System NaAlSiO4-KAlSiO4-SiO2
A study, of the alkali-feldspar join $$KAlSi_{3}O_{8}-NaAlSi_{3}O_{8}$$ in the system $$NaAlSiO_{4}-KAlSiO_{4}-SiO_{2}$$ shows an unbroken series of solid solutions between these alkali feldsparsExpand
The influence of elastic strain on the shape of particles segregating in an alloy
An estimate is given of the way in which the strain energy associated with a particle of precipitate depends upon the shape of the particle. It is shown that the energy can only be reduced if theExpand
