A Laboratory Study of the Physical Properties of Colloids
<p>The colloidal state of matter exhibits phenomena due to its physical properties which may contribute heavily to the mechanical weathering of rocks and minerals. This paper is primarily a discussion, evaluation, and correlation of these phenomena as related to natural geologic conditions. …

Trace elements in agricultural soils of Saanich Peninsula, Vancouver Island, British Columbia, Canada
The concentrations of trace elements in 30 Saanich Peninsula agricultural soil samples were determined by acid digestion and inductively coupled plasma - optical emission spectroscopy (ICP-OES). A comparison of the results obtained to a 1995 BC Ministry of Environment data indicated that As, Cu, …

Nutritional contribution of atmospheric deposition to the Strandveld vegetation of West Coast South Africa Justine Muhoro Nyaga.
… depends on the balance between rates of nutrient inputs and losses. Nutrients may be lost through fire and displacement of ash, herbivory, leaching and volatilization. The main pathways through which nutrients may be acquired are weathering of rock and atmospheric deposition. Symbiotic …

Sediment chemistry as an archive of provenance and weathering in the Mekong River Basin
The chemical weathering of rocks, in particular silicate weathering, has been proposed to be an important natural carbon-removal process that regulates the Earth’s climate over millions of years. Tectonically active regions, such as the sub-Himalayan region, are considered a hotspot of silicate …

Water on Calcite (10.4) and K-Feldspar (001) - Adsorption Structure and Desorption Kinetics -
… processes such as biomineralization, weathering of rocks, and atmospheric ice nucleation by mineral dusts. These small-scale processes at mineral-water interfaces have tremendous impact on our environment. For instance, ice nucleation caused by mineral dusts changes the properties of …

Isovolumetric Weathering of Granite in Wake County, North Carolina
Saprolite, formed by chemical weathering of rocks near the earth's surface, holds water, serves as a parent material of soils, and is a medium for waste disposal. Saprolite formation consumes CO₂ and may stabilize atmospheric CO₂ levels. This dissertation examined the influence of joint orientation …
