The aim of the research reported herein was to study the weathering of glauconite taking place in a Luvisol profile developed on quartz-glauconitic sand in Góra Puławska (eastern Poland) using X-ray diFouriermetransforminfraredspectroscopyed spectroscopy, Mossbauer spectroscopy, SEM EDS, and an optical microscope.
Three stages of soil development corresponding to specific landscapes were observed within a 2-m deep profile: 1) a stabilisation surface within an active drift sand landscape, 2) an A-horizon that developed on a stabilised drift sand landscape and 3) a pronounced podzol that developed in a stabilised landscape from the last glacial.
Three representative weathering profiles developed on the hilltops indicate that sand represents more than 50% by weight throughout most of the weathering profile, and silt- and clay-size fractions are also well represented, filling the interstices among corestones.
That will not begin until later this year, and in the interim the city has developed a "transition center" on Sand Island.
The interpretational limits largely result from a lack of laboratory experiments that focus on developing analogues for sand injection.
For the slopes on the sedimentary terrain with little cohesion, the high permeability of the materials ensured significant pore pressure was developed at the sand-shale interface.
The State Department had earlier concluded that Keystone would have little impact on developing the tar sands – and that the oil would be extracted anyway.
State Department XL Keystone pipeline's analysis, dismissing the pipeline's impact on developing dirty tar sands, was created by companies tied to Big Oil... who would have guessed?
Native American tribes, building on their treaty rights, are blocking efforts to develop tar sands pipelines and new coal export facilities; non-Native allies are joining in.
Several large companies postponed decisions on whether to go forward with big projects to develop oil sands in Canada, for instance, and smaller independents slashed their exploration budgets.
