Characterization of clay mineral fractions in tuffisitic kimberlite breccias by X-ray diffraction
Kimberlite is described as a diverse and complex hybrid rock in the literature. It is also described as volatile rich, potassic, ultrabasic, igneous rocks that occur as volcanic pipes, dykes and sills1. The minerals present in kimberlites vary widely and can include from trace to predominance any of the following minerals: apatite, calcite, chlorite, diopside (pyroxene), magnetite, monticellite...
متن کاملIn situ characterization of aluminum-containing mineral-microorganism aqueous suspensions using scanning transmission X-ray microscopy.
In situ characterization of colloidal particles under hydrous conditions is one of the key requirements for understanding their state of aggregation and impact on the transport of pollutants in aqueous environments. Scanning transmission X-ray microscopy (STXM) is one of the few techniques that can satisfy this need by providing element- and chemical-state-specific 2-D maps at a spatial resolut...
متن کاملORIENTING INTERNAL STANDARD METHOD FOR CLAY MINERAL X-RAY ANALYSIS by
USE of a platy internal standard that will orient to the same degree as clay minerals preserves the relative diffraction intensities between the basal reflections from the platy components, regardless of degree of orientation. The method is illustrated with basic zinc chloride and pyrophyllite as the internal standards for quantitative clay mineral anMysis in the systems kaolinite-liVid illite ...
متن کاملTransmission X-ray microscopy reveals the clay aggregate discrete structure in aqueous environment.
The utilization of new transmission X-ray microscopy (TXM) using the synchrotron photon source enable for the first time the study in three dimensions microsize clay particles in aggregates in their natural aqueous environment. This technique makes possible remarkable accurate images of nanosize mineral interparticle structure which forms a new nanocomposite. The Birdwood kaolinite/LDH aggregat...
متن کاملTransmission X-ray Microscopy (TXM) Reveals 3-D Nano-structure of Clay-water Suspension
The unusual behaviour of smectites, their ability to change volume when wetted (swelling) or dried (shrinking), makes soil rich in smectites very unstable and dangerous for the building industry due to possible or likely movement of building foundations and poor slope stability. These macroscopic properties are dominated by the structural arrangement of smectites finest fraction. Here, we show ...
