The low concentrations of niobium, tantalum and titanium observed in island-arc basalts are thought to result from modification of the sub-arc mantle by a metasomatic agent, deficient in …
Clay mineral crystallinity and crystallite (domain) size data determined by X‐ray diffraction (XRD) are methods extensively used in the characterization of very low‐grade metamorphic …
A text which aims to help undergraduate students in geology to recognize and interpret metamorphic textures and microstructures in thin-section. For lecturers and postgraduates in …

Abstract Fairly strong (r= 0.75–0.85) positive linear correlations were found between crystallinity indices (peak widths) measured on the first two basal reflections of chlorite and …
Following a round-table discussion at the Mid-European Clay Conference in Dresden 2014, new recommendations for illite 'crystallinity'Kübler index standardization have been agreed …
A detailed knowledge of Himalayan development is important for our wider understanding of several global processes, ranging from models of plateau uplift to changes in oceanic …
Instrumental settings for determination of illite/muscovite 'crystallinity'(half‐height width of the 10‐Å X‐ray diffraction peak) and the limits of the anchimetamorphic zone adopted by …

The value of peak width at half-height for the illite 001 XRD reflection is known as the Kubler index or the illite 'crystallinity'index. This measurement, which has been related to the …
Abstract In India, the Dagshai and overlying Kasauli Formations represent the oldest exposed continental foredeep sediments eroded from the Himalayan orogen. 40Ar/39Ar …
