5203 |a"When dealing with clay-rich samples, separating and identifying authigenic from detrital minerals into distinct subsamples are crucial steps in elucidating geological parameters for tectonic, economic and geochronological studies. The following report outlines a clay separation procedure employed at the Geological Survey of Canada to isolate authigenic and detrital minerals into different silt and clay fractions, quantifying non-clay minerals in the separated samples, and estimating the crystallinity index of clay minerals. The grain size of the fractions obtained using this procedure are examined using a laser particle size analyzer, while the identification of their mineralogical composition is achieved using X-ray diffraction analysis. This protocol provides guidelines for clay sample preparation before chemical and geochronological analyses to determine geological processes such as: diagenesis, weathering, faulting (fault slip and fluid circulation), and host-rock alteration associated with mineralization"--Abstract, page i.
