Sentence examples for particle weathering from inspiring English sources

Lumsdon et al. [58] measured arsenopyrite/pyrite particle weathering in laboratory simulations and observed that dissolved As concentrations in solutions were the lowest when the weathering products had advanced past jarosite to amorphous iron oxides, suggesting a greater degree of As adsorption on the iron oxides than jarosite.

Materials in various particle sizes are subject to weathering processes at field condition; however, the particle size dependent oxidation rate has not been investigated for understanding entire geochemical behavior at a mining site.

It is important to measure the current flux of inflow dust particles, from which the weathering effect in the past can be inferred.

Whereas we cannot completely refute this hypothesis through quantitative argument, qualitatively the number and size of impacts on the surface of such small asteroids as Itokawa that could produce an environment energetic enough to physically weather particles seems unlikely.

Fuel particles, distributed in a heterogeneous pattern across the watershed, are weathering and releasing 90Sr from the fuel matrix.

Evidence on black carbon's climate impacts has been building since at least the mid-1990s, when Ramanathan and colleague Paul Cruzan, a Nobel prize winning atmospheric chemist from the Max Planck Institute for Chemistry, first speculated that "brown clouds" laden with the dark particles influence weather patterns over South Asia, a hypothesis that was supported by future research.

Seemingly buoyant particles sank as they weathered, were colonised by organisms or caught up in storms.

This indicates that neither set of samples had lost any fine material (or any other fractions) since deposition, and that the historical samples had not been substantially weathered (producing finer particles than the original particle distribution) nor had additional, substantial fine-grained organic matter.

two types of granite weathered soil with a controlled particle size and gravel (25 mm) were compacted.

Erosion largely depends on the release of particles from the weathering rock, which in turn requires a degree of dissolution of the more soluble grains.

The space weathered rims on them are observed but less developed on the Itokawa particles collected from the second touchdown site.
