the strategy of sampling should favour chemostratigraphical work both vertically and laterally, whereby the samples were intended to define from homogeneous fine- to medium-grained GdA Sst (GdA = Grès d'Annot)
all collected samples are to be treated with care from the stage of sampling and until all geochemical data are secured - to prevent data error 
all the collected samples are analysed with thin section microscopy, heavy mineral count, XRD and XRF, and a selection of the collected samples are analysed with SEM and micro probe  
determine - is grain size controlling the distribution of immobile elements, stable heavy minerals, immobile trace elements within the defined sample criteria
decide - which heavy minerals are stable in the GdA Sst and which heavy mineral ratios are representative for plotting
do the heavy mineral rates demonstrate any fingerprints in cross-plots, which might enable chemostratigraphy (vertical and lateral correlation) in the GdA Fm?
evaluate the XRF-data and apply multi variate analysis - to identify correlative immobile elements (correlation coefficient above 0.7)
do the immobile element analysis demonstrate any fingerprints in cross-plots, which might enable chemostratigraphy in the GdA Fm?
