Evaluation and quality control results of particle size estimation by MIR prediction, Pb-isotope and MMI-extraction analysis and results of the GEMAS ring test for the standards Ap and Gr. Rigorous quality control (QC) is one of the keystones to the success of any regional geochemical mapping programme. For the EuroGeoSurveys (EGS) GEMAS (Geochemical mapping of agricultural and grazing land soils) project 2211 samples (including field duplicates) of agricultural soil (Ap, Ap-horizon, 0-20 cm) and 2118 samples (including field duplicates) from land under permanent grass cover ("grazing land" -Gr, topsoil 0-10 cm) were collected from a large part of Europe, centrally prepared (air dried, sieved to <2mm, homogenised and split into sub-samples) and randomised prior to being sent out to contract laboratories. QC consisted of (I) collection of a field duplicate at a rate of I in 20 field samples, (2) preparation of two large project standards ("Ap" and "Gr") for insertion between the routine project samples, (3) preparation of an analytical replicate from each field duplicate and (4) randomisation of all samples prior to analysis.
