Techniques in Sedimentary Geochemistry: (1) Separation of the Detrital and Non-Detrital Fractions of Limestones

D. M. Hirst, G. D. Nicholls


A method is outlined whereby the contents of ten trace elements in the non-detrital fraction of limestones can be determined spectrographically down to values of the order of 0.05 ppm. For five other elements the method is useful but less sensitive. The method is based on the mixed precipitants technique of Mitchell and Scott (1947) and Heggen and Strock (1953) modified to satisfy the requirements of investigations in sedimentary geochemistry.
