Kaolinitic Clay

Using Ptolemaic to late antiquity pottery assemblages from Aswan (ancient Syene) as a case study, we demonstrate the imperative nature of petrographic analyses combined with geological field surveys when investigating ancient potting centres. The combination of archaeological (i.e. abundance of ceramics, vessel shapes etc.), macroscopic and natural-scientific methods allows the reconstruction of the possible extraction areas of clays utilised in Aswan, Upper Egypt. Knowledge of specific clays and their compositional characteristics helps to establish archaeometric reference groups, necessary for differentiating kaolinitic clay sediments of the Aswan area from similar geological environments further down the Nile valley.

AbstractThe use of transmission electron microscopy in association with other methods is described for the characterization of Brazilian industrial clays, especially kaolinitic-halloysitic clays. Examples are presented from: (a) tubular 7 Å-halloysites and the characterization of mixtures with ordered and disordered kaolinites in residual china clays; (b) tubular kaolinitic clay from Piedade, São Paulo; (c) platey 10 Å-halloysite from Poģos de Caldas, Minas Gerais; (d) rolled forms similar to 10 Å-tubular halloysite formed by repeated K Ac intercalation in well ordered kaolinite; (e) use of particle shape and size of kaolinite crystals in the São Simão, São Paulo ball clays as orientation for good sanitaryware ball clays; (f) characterization of gibbsite crystals in high alumina gibbsite/kaolinite clays; (g) antigorite as a clay mineral; (h) electron optical studies of thermal phase transformations involving tubular kaolinite, halloysites, antigorite, chrysotile, talc and pyrophyllite mono crystals.

Mesozoic Sediment

Early Cretaceous unconsolidated quartz sand and kaolinitic clay deposits in the lowlands of Nova Scotia are preserved in narrow half-grabens obscured by glacial drift. The Chaswood Formation sediments can be subdivided into three members; upper and lower members dominated by cyclical sand–mud facies of fluvial origin and the middle member with lignitic clay of lacustrine origin. Ferruginous oxisols are common in the fine-grained facies of the upper and lower members. Seismic data indicate that Chaswood Formation strata in the Elmsvale Basin are deformed into steeply dipping faults and fault-related folds (Rutherford Road fault zone). An Aptian–Albian age for this tectonic event is inferred from synsedimentary deformation and from the angular unconformity spanning the Late Cretaceous and Tertiary that truncates the Chaswood Formation. Exhumation of a thick cover of Mesozoic sediment (1–2 km) is needed to account for the preservation of Chaswood Formation outliers after ~80 Ma of erosion. The half-grabens that host the Chaswood Formation were formed in the Mesozoic and were antecedent to the present-day structurally controlled lowlands.

AbstractVarved clay deposits from ice-dammed lakes are a particularly important and broadly applied raw material used for the production of high-quality ceramics (red bricks, roof tiles, etc.), but the mineralogy and geochemistry of these sediments are not fully understood. The aim of the present study was to determine the chemical and mineralogical composition of ice-dammed lake sediments of the Lębork deposit. Major-element analysis of the compositions of selected samples from the ice-dammed lake clays was performed by X-ray fluorescence (XRF) and trace elements were determined by inductively coupled plasma-mass spectrometry. The mineralogical composition of clay samples was determined by X-ray diffraction (XRD). Analyses of the chemical composition of the ice-dammed lake clays of the Lębork deposit showed that the dominant component was SiO2 with a mean content of 56.13 wt.%; the second most abundant component was Al2O3, with a mean content for the entire deposit of 11.61 wt.%. Analysis by ICP-MS indicated the presence of rare earth elements (REE), e.g. cerium, neodymium, lanthanum, and praseodymium; their mean contents are: 56.9, 27.0, 26.3, and 7.3 ppm, respectively. Mineralogical analysis of the varved clays identified quartz, muscovite, calcite, and clay minerals – illite, kaolinite, and montmorillonite. The material filling the Lębork basin is characterized by small lateral and vertical variability in chemical composition. The results of the present study may be of considerable importance in determining the parent igneous, metamorphic, and sedimentary rocks, the weathering products of which supplied material to the ice-dammed lake, as well as in determining the mechanisms and character of the sedimentation process itself.
