Abstract

Very little information has been published on sampling and sample preparation procedures, yet these are paramount to the success of chemostratigraphy as, without good quality data, it is not possible to produce robust chemostratigraphic schemes. This is especially true of studies involving the analysis of cuttings samples, which have to be washed, sieved, meticulously ‘picked’ and ground prior to analysis. Core and field outcrop samples are simply described and then ground. The principal analytical techniques used to acquire inorganic geochemical data are ICP-OES (Inductively Coupled Plasma-Optical Emission Spectrometry), ICP-MS (Inductively Coupled Plasma-Mass Spectrometry) and XRF (X-ray Fluorescence). For the best quality data acquired for the largest number of elements, it is recommended that a combination of ICP-OES and ICP-MS are used. The XRF technique produces data for a lesser number of elements, but can be useful where rapid analysis of samples is required. Irrespective of the analytical technique used to acquire data, however, it is important to check the results for accuracy (closeness of result to ‘known’ values of particular elements), precision (repeatability of results) and detection limits, before the data can be utilized for chemostratigraphic purposes.
