The GEMAS project collected samples from grazing land (n=2118, 0-20cm depth) and agricultural soil (n=2211, 0-10cm depth) at a scale of 1 site/2500km2 in most of Europe1. Elemental analysis using different extractions (Aqua Regia and MMI), whole soil XRF data and Q-ICPMS lead isotope data have been published1. Here we report high-precision 87Sr/86Sr results for the first 1000+ samples.

Strontium is a ubiquitous trace element present in rocks, soil, waters, plants, and animals. The 87 Sr/ 86 Sr ratio is a function of the geochemical origin, Rb concentration, and age of the source rock. Because of the high mass of Sr, the ratio is essentially unchanged as the rock weathers and moves through the water cycle and food chain.

The isotope ratios of Sr are useful tracers for studying parent material sources, weathering processes, and biogeochemical cycling. Mineralogical and geochemical investigations of two lateritic weathering covers, in an area close to the Tropic of Cancer (Guangxi Province, southern China), were undertaken to study the regional weathering processes and Sr isotopic sources.

Feb 01, 1998· Strontium isotopes can be a powerful tool in ecosystem studies, both as a tracer of nutrient sources and as a monitor of the weathering process.
