The Geological Survey of Northern Ireland (GSNI) and the British Geological Survey (BGS) completed a regional geochemical survey of Northern Ireland's soils between 2004 and 2006. Sampling and quality control were undertaken according to the G-BASE protocol of BGS. 6,862 sites were sampled (at depths of 20 cms and 50 cms) an average of one site per 2 km2. This dataset are the results of Major Oxide and Trace Element analysis of shallow soils (20 cms) by XRF presented as a point shapefile.
Analytes include: Ag, Cd, In, Sn, Sb, Te, I, Cs, Ba, La, Ce, Na2O, MgO, Al2O3, SiO2, P2O5, SO3, K2O, CaO, TiO2, MnO, Fe2O3, Cl, Sc, V, Cr, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Br, Rb, Sr, Y, Zr, Nb, Mo, Nd, Sm, Yb, Hf, Ta, W, Tl, Pb, Bi, Th, U.
