REE minerals in Catalão II, Goias, Brazil [PDF]

, 2012
National audienceThe REE minerals pyroxenites and sövites of Catalão II show a substantial enrichment in REE from the magmatic stage. The activity of carbonate and CO32-/ PO43- ratio have played an important role in the formation of REE-carbonate ...

Crystallisation sequence of a REE-rich carbonate melt: an experimental approach [PDF]

, 2021
International audienceCarbonatites host Earth's main REE deposits, with bastnaesite (LREE)CO 3 F being the main economic REE-bearing mineral. However, bastnaesite mineralisation processes are debated between hydrothermal or magmatic origin.

REE fractionation during granite weathering and removal by waters and suspended loads: Sr and Nd isotopic evidence [PDF]

, 2001
Very few studies deal with REE (rare earth element) mobility within the system soil–soil solution–streamwater. In this article, we try to characterize the fractionation and the migration of the REE in a granite-derived soil system located in a small ...

Soil Type Controls the Effects of the Nitrification Inhibitor DMPP on Nitrate Leaching and Mineral N Retention Under Simulated Heavy Rainfall

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Nitrate (NO3−) leaching is a major nitrogen (N) loss pathway in agriculture and may increase with more frequent heavy rainfall. Nitrification inhibitors, such as 3,4‐dimethylpyrazole phosphate (DMPP), can reduce these losses, but their effectiveness under frequent heavy rainfall events remains unclear, which limits their targeted ...

Distribution and origin of major and trace elements (particularly REE, U and Th) into labile and residual phases in an acid soil profile (Vosges Mountains, France). [PDF]

, 2004
A seven step sequential extraction procedure has been conducted on a podzolic soil profile from the Vosges Mountains in order to determine the ability of several elements to be released to the environment.

REE fractionation and quantification of sediment source in the Yellow Sea mud deposits, East Asian marginal sea

, 2021
Discriminating sediment sources quantitatively of several unique shelf-mud deposits in the Yellow Sea has received considerable attention, because they are active sedimentary depocenters that can elucidate the river sediment dispersal patterns and the ...

New constraints on the postglacial evolution of Lago Maggiore, Northern Italy

Journal of Quaternary Science, EarlyView.
ABSTRACT Lago Maggiore is situated in an overdeepened valley reach at the southern margin of the European Alps, and its thick sediment infill allows the reconstruction of the postglacial valley and lake evolution. We study here the sedimentary succession in the lower Ossola Valley, which is infilled by ~500 m of deposits. In a marginal position, a core

Rock, paper, pigeon: Exploring speculative ecologies through more‐than‐human play

People and Nature, EarlyView.
Abstract As interactive technologies and playful storytelling increasingly explore posthuman and more‐than‐human perspectives, opportunities emerge to reframe natureculture heritage—as it recognizes that human lives, technologies and societies are always connected with the lives and environments of other species and ecosystems—as intrinsically ...

The Hidden Harvest: Harnessing Colorado's Geodiversity and Environmental Heterogeneity for Sustainable Agritourism

Sustainable Development, EarlyView.
ABSTRACT Colorado's geologic, pedologic, topographic, hydrological, and climatic contrasts create strong but under‐synthesized opportunities for sustainable agritourism. This review investigates how geodiversity, and the broader environmental heterogeneity within which it operates, can be used to diversify farm income, strengthen place‐based visitor ...

Pozzolanic Activity Assessment of LUSI (LUmpur SIdoarjo) Mud in Semi High Volume Pozzolanic Mortar [PDF]

, 2012
LUSI mud obtained from the mud volcano in Sidoarjo, Indonesia, is a viable aluminosilicate material to be utilized as pozzolanic material. LUSI is an abbreviation of the local name of the mud, i.e., Lumpur Sidoarjo, meaning Sidoarjo mud.
