Distribution and Origin of Analcime in Marginal Lacustrine Mudstones of the Green River Formation, South-Central Uinta Basin, Utah
Robert R. Remy,Ray E. Ferrell +1 more
TL;DR: X-ray powder diffraction and thin section analyses indicate that marginal lacustrine mudstones of the Green River Formation in the south-central Uinta basin, Utah, contain abundant analcime as mentioned in this paper.

Mineralogy and geochemistry of Terra Rossa soils, western Sicily: insights into heavy metal fractionation and mobility
TL;DR: In this article, the distribution of heavy metals in typical Terra Rossa soils and their partitioning in specific soil phases are estimated on the basis of the comparative evaluation of bulk contents, results from sequential chemical extraction procedure (SEP) and scanning electron microscopy/energy dispersive X-ray analysis ( SEM EDX ).
Journal ArticleDOI
Correlation between surface area and Atterberg limits of fine-grained soils
TL;DR: In this paper, the Atterberg limits are defined as the point at which the consistency of a fine-grained soil changes from a semi-solid state to a plastic state and finally to a liquid state.

Trace elements contamination of agricultural soils affected by sulphide exploitation (Iberian Pyrite Belt, Sw Spain)
TL;DR: In this paper, the degree of pollution by trace elements as a consequence of the extraction and treatment of sulphides in the Riotinto mining area (Iberian Pyrite Belt) has been investigated.

The Buwambo kaolin deposit in central Uganda: Mineralogical and chemical composition
TL;DR: In this article, the authors analyzed the mineral properties of the Buwambo kaolin from the Buganda-Toro cover rocks and showed that it is composed mainly of SiO2 and Al2O3, with other oxides being present in trace amounts.
