These low-energy tidal environments are typically dominated by organic-rich, estuarine deposits, but during high-energy events, water carrying significant amounts of sand can flood the mangroves and leave behind coarse inorganic sediment layers.
Some also dismiss a scenario that the State Department laid out, in which oil prices drop, new pipelines are not available, and rail costs remained high and therefore a significant amount of tar sands expansion is too costly to pursue.
The soil wetting agents were less effective at treating water repellent sand containing a significant amount of OM than sand with low OM content.
From the experiences of past earthquakes, it is found that sandy deposits which contain significant amount of fine-grains (silty sands, clayey sands) and/or gravel liquefy during earthquakes and cause lateral spreading [3, 4, 5].
Significant amounts of the sand have been replaced or displaced by iron minerals giving an average ore grade of around 25 wt% iron.
Aquifer media The main lithological constituents of the principal aquifer in the study area are a mixture of gravel and sand with significant amount of silt and clay, therefore the rating value of this media is eight (Fig. 11c).
This aquifer is also widespread over the whole area and consists mainly of mixture of gravel and sand with significant amount of silt and clay in some parts of the aquifer.
Extraction processes in the oil sand industry (northern Alberta, Canada) produces significant amount of waste slurries [0.25 m3/barrel of crude oil produced (Mikula et al. 1996)] characterized by caustic pore fluids and ore minerals suspended in bitumen contaminated liquids.
Sands said he expects a significant amount of money to be committed toward expanding enrollment in tech fields at many campuses in Virginia.
Extracting the gooey sands and separating the oil from them consumes a significant amount of energy, making the projects a growing source of greenhouse gases.
I miss a significant amount of school.
