The Tellus geochemical survey began in the summer of 2004 and was completed in 2006. This was a multi-media survey of soil, stream-sediment and stream-water samples in rural and urban areas. The results will establish the natural geochemical baseline signature and any man-made overprint. For rural soils, samples were collected at an interval of approximately one site per 2 km2 (about one site every 500 acres). Samples were collected from two depths (20 cm and 50 cm) at each site to provide an insight into vertical geochemical variations. The samples were analysed by XRF for Ag, Al2O3, As, Ba, Bi, Br, CaO, Cd, Ce, Cl, Co, Cr, Cs, Cu, Fe2O3, Ga, Ge, Hf, I, In, K2O, La, MgO, MnO, Mo, Na2O, Nb, Nd, Ni, P2O5, Pb, Rb, SO3, Sb, Sc, Se, SiO2, Sm, Sn, Sr, Ta, Te, Th, Tl, TiO2, U, V, W, Y, Yb, Zn, Zr. Au, Pt and Pd were analysed by 10g Fire Assay SO4 by Aqua Regia ICP-MS pH and Loss on Ignition were also recorded. The survey followed the British Geological Survey's Geochemical Baseline Survey of the Environment (G-BASE) standard developed over many years that defines the specifications for mapping the regional geochemistry of the United Kingdom.
