Journal ArticleDOI
Illite-smectite structural changes during metamorphism in black Cambrian Alum shales from the Baltic area
Holger Lindgreen,Victor A. Drits,Boris A. Sakharov,Alfred L. Salyn,Per Wrang,Lidia G. Dainyak +5 more
TL;DR: In this paper, the authors used X-ray diffraction (XRD) and infared spectroscopy (IR) to determine the mechanism of the clay transformation in early diagenetic and anchimetamorphic black shale.
Journal ArticleDOI
The structure and diagenetic transformation of illite-smectite and chlorite-smectite from North Sea Cretaceous-Tertiary chalk
Holger Lindgreen,Victor A. Drits,Boris A. Sakharov,Hans J. Jakobsen,Alfred L. Salyn,Lidia G. Dainyak,H. Krøyer +6 more
TL;DR: In this paper, the detailed structure and diagenetic clay transformation was investigated using X-ray diffraction (XRD) including simulation with a multicomponent program, and the structural formulae were determined from chemical analysis, infrared (IR) and 27 Al NMR spectroscopy and XRD, and particle shape by atomic force microscopy (AFM).
Journal ArticleDOI
Tobelitization of smectite during oil generation in oil-source shales. application to north sea illite-tobelite-smectite-vermiculite
Victor A. Drits,Holger Lindgreen,Boris A. Sakharov,Hans J. Jakobsen,Alfred L. Salyn,Lidia G. Dainyak +5 more
TL;DR: In this paper, the authors demonstrate a link between the two reactions: NH3 released from kerogen during maximum oil generation is fixed as NH 4 + mica or tobelite layers formed from smectite or vermiculite layers in I-S, in a diagenetic interval which they name the Tobelitization window.
Journal ArticleDOI
Structural and chemical heterogeneity of illite-smectites from Upper Jurassic mudstones of East Greenland related to volcanic and weathered parent rocks
TL;DR: In this paper, the phase composition and layer sequences were determined by X-ray diffraction (XRD), the distribution of octahedral cations over trans - and cis -octahedra by thermal analysis, the structural formulae by XRD, Mossbauer spectroscopy, and total chemical analysis, and the short-range order in isomorphous cation distribution by infrared (IR) and Mossbau spectroscopies.
Journal ArticleDOI
Interpretation of the nontronite-dehydroxylate Mössbauer spectrum using EFG calculations
TL;DR: In this article, the structure model of dehydroxylated Fe 3+ -rich dioctahedral 2:1 phyllosilicates (celadonites, glauconites and nontronites) was studied using Mossbauer spectroscopy.
