Title

Geochemical Baseline Survey Of The Environment (G-BASE) For The UK.

Abstract

The G-BASE programme involves systematic sampling and the determination of chemical elements in samples of stream sediment, stream water and soil, to build up a picture of the surface chemistry of the UK. The average sample density for stream sediments and water is about one site per 1.5-2km square, and for soils one site per 2km square. Analytical precision is high with strict quality control to ensure countrywide consistency. Results have been standardised to ensure seamless joins between geochemical sampling campaigns. The data provide baseline information on the natural abundances of elements, against which anomalous values due to such factors as mineralisation and industrial contamination may be compared. Analytical data for the 150 microns fraction of soil and stream sediment samples are available for some or all of: Ag, As, B, Ba, Bi, Be, Ca, Ce, Cd, Co, Cr, Cs, Cu, Fe, Ga, K, La, Li, Mg, Mn, Mo, Nb, Ni, P, Pb, Rb, Sb, Se, Sn, Sr, Th, Ti, U, V, Y, Zn, and Zr. Most water samples have been analysed for alkalinity, pH, conductivity, F and U and some for multi-element analyses including Al, Cl, Na, Si, SO4,NO4, and TOC. The project now routinely determines the elements listed in the <2mm fraction of surface soils.

Additional information source

Regional geochemical Mapping commenced in the Caithness and South Orkney area carried out by the Institute of Geological Sciences (IGS -now BGS). Projected completion by 2015 Complete for Scotland, Wales, West Midlands, Northern England, Humber-Trent, Central England and East Anglia. Southern England ongoing. Soil samples average 1 per 2km square, sediment samples average 1 per 1.75 km square collected using 1:50 000 OS base maps. Geochemical mapping carried out according to International Geochemical Sampling methods described by IGCP 259.
