"The samples were analysed at the Environmental Geochemistry and Geochronology Laboratory at the Research School of Earth Sciences, ANU using the Neptune MC-ICP-MS"			
			
Version history	4/09/2013	V1.0 of the database. Includes all samples collected from F06-F13 and Sr isotope values for soils and plants for all of F12	
			
			
Worksheet descriptions			
Bioavailable Sr isotope ratios France			
	Sample ID	"The sample ID can be used to identify the sample in our data tables and archives. Current standard is F-year-sample#, for example F11-02 means the second sample collected in 2011. "	
	Researcher	Names of the researchers collecting the samples	
	"Latitude, Longitude, Elevation"	Coordinates of the sample site	
	Outcrop type	We distinguish different types of outcrops:	
		"Outcrop: A natural outcrop of rock, as far as we could identify. Not uncovered through recent human activity."	
		"Roadcut: Along a major road, rocks unearthed by human activity."	
		"Quarry: Outcrop created by human activity, often no longer in use."	
		Field: A sample collected from a field or meadow.	
		Turned over tree: A sample collected from or beneath a turned over tree that has excavated some fresh soil layers.	
		Ground exposure: A sample collected from ~10-20 cm deep hole dug by us. 	
	Setting	"This is a short description of our observations in the field, such as the proximity of human activities (agriculture, forest plantations) or clear indications of other recent influences. "	
	Geologic background	"Summary of the geologic information from the 1:1M BRGM geologic map (Chantraine et al., 2005) including the geologic region, rock type, geologic unit, major lithologies and age ranges. N_Caisson correlates to the name given to the geologic unit in the shapefile version of the geologic map and thus could be used to join the isotope data directly with the geologic map."	
	Sample descriptions	"Field observations during sample collection, such as rock, soil and plant type and characteristics. We used the Unified Soil Classification System and distinguished between Topsoil, Subsoil and Field samples"	
	87Sr/86Sr ratios	Strontium isotope ratios for soil leachates and plant samples	
SRM987	"Compilation of SRM987 values produced during this project between 2011-2012 at the Environmental Geochemistry and Geochronology Laboratory at the Research School of Earth Sciences, ANU."		
Reproducibility	RSES soil is an inhouse soil standard		
	"GEMAS Project are two soils (Ag and GR) used as a blind test for our laboratory. They were supplied by the Gemas Project (Jurian Hoogewerff and Reimann Clemens, personal communication)"		
	"Duplicates are samples that underwent the complete procedure multiple times, Reruns are samples ran at different times on the same Neptune MC-ICP-MS"		
			
Additional information			
Method	Soils were leached with 1 M NH4NO3-solution according to DIN 19730 (1997-06) . Plants are total digestions in conc. HN03		
Blanks	"Instrument blanks were run every two samples. Total procedural blanks are 50-250 pg total Sr, using procedural blanks with LORBSR Spike added and measured on a TRITON mass spectrometer at RSES, ANU. Only samples were the total blank contribution was less than 0.2% of 88Sr have been accepted into the dataset"
