(2006)This chapter discusses clay mineral identification and quantification and reviews the corresponding literature. Quantitative analysis is most often performed to obtain percentages of clay minerals either in the bulk rock ...
-
(2006)Because of their great abundance, high specific surface area, layer charge, laminar morphology, and chemical reactivity towards both neutral and charged species, clay minerals are of great importance to agriculture, industry, ...
-
(2006)In this chapter we will see how to predict the course of chemical reactions occurring during the geological disposal of CO 2, building on the thermodynamic and kinetic grounds that were reviewed in previous chapters.
-
(2006)The structure and composition of clay minerals are modified by heating. The concomitant changes in properties can be exploited for practical purposes. The actual temperatures at which changes occur vary greatly from one ...
-
(2006)Paleomagnetic and rock magnetic investigations were carried out on four gravity cores recovered from the western continental rise of the Antarctic Peninsula during the SEDANO II cruise of RV OGS-Explora. The studied cores, ...
-
(2006)Fourier transform infrared (FTIR) spectroscopy is a rapid, economical, easy, and non-destructive technique. The IR spectrum of a clay mineral is sensitive to its chemical composition, isomorphous substitution, layer stacking ...
-
(2006)Stable light isotopes in ratite eggshells have been shown to be reliable indicators of shifts in climate and environmental conditions in the past. Here, we show that δ18O and δ13C values in fossil and modern ratite eggshells ...
-
(2006)Phyllosilicates, and among them clay minerals, are of great interest not only for the scientific community but also for their potential applications in many novel and advanced areas. However, the correct application of ...
-
(2006)The joint application of electromagnetic techniques for near-surface exploration is a useful tool for soil pollution monitoring and can also contribute towards describing the spatial distribution of pollutants. The results ...
-
(2006)Despite a long research history over the past 150 years, the geometry, kinematics, and dynamic evolution of the Himalayan orogen remain poorly understood. This is mainly due to continued emphasis on the two-dimensionality ...
-
(2006)This study examines the δ18O and δ13C composition of cryogenic carbonate deposits in relation to the initial δ18O, δ13CDIC and chemical composition of the water from which it precipitated. This study focuses on cryogenic ...
-
(2006)The molecular environment of iodine in reference inorganic and organic compounds, and in dry humic and fulvic acids (HAs and FAs) extracted from subsurface and deep aquifers was probed by iodine L3-edge X-ray absorption ...
-
(2006)The Mawson Formation and correlatives in the Transantarctic Mountains and South Africa record an early eruption episode related to the onset of Ferrar-Karoo flood basalt volcanism. Mawson Formation rocks at Coombs Hills ...
-
(2006)Kahak salt playa in South Khorasan province of Iran, have special geomorphological characteristics by the presence of ephemeral saline lakes, wetlands, salt crusts, surface accumulations of salt and zones of patterned ...
-
(2006)The key ingredients to successful real-time reservoir management, also known as a “closed-loop” approach, include efficient optimization and model-updating (history-matching) algorithms, as well as techniques for efficient ...
-
(2006)New and previously published micro-gravity data are combined with InSAR data, precise levelling and GPS measurements to produce a model for the processes operating at Krafla volcano, 20 years after its most recent eruption. ...
-
(2006)Polycyclic aromatic hydrocarbons (PAHs) in soil originate from various sources under different spatial scales. Coregionalization analysis is more revealing than univariate geostatistical analysis. Scale-dependent spatial ...
-
(2006)This paper examines the surface sediments collected from Dongping Lake in China for speciation and distribution of toxic heavy metals (Cu, Pb, Ni, Cd) in different grain size fractions, and for the factors that need to be ...
-
(2006)Various soil zones such as Bw, C1, and C3 are developed on spilite. Montmorillonite, vermiculite and chlorite is moderately occurred in the C1 and C3 soil zones, in contrast montmorillonite and vermiculite are absent in ...
-
(2006)The forms, rotational patterns and trends of hysteretic loops of dissolved organic carbon (DOC) and nitrate (NO3) were investigated in three headwater Mediterranean streams during one autumn–winter period using two ...
