The IRHUM (Isotopic Reconstruction of Human Migration) database is a web platform to access, explore and map strontium isotope data. It is maintained at the Research School of Earth Sciences, ANU. Details about the data and their source is located in the individual layer files.

Kriging with external drift for soil and plant samples

Layer from Malte, 1 year, 9 months ago

The dataset consists of 540 sample locations, with a total of 968 individual samples.We grouped the lithological units and their strontium isotope ranges into 5 isotope groups. The contribution of each lithological unit to its isotope group was weighted by the relative area of that lithological unit.

Layer from Malte, 4 years, 8 months ago

This layer provides the mean 87Sr/86Sr isotope values for the lithological units of France. The strontium isotope data is the IRHUM database (layer Sr_france_t2_v4) and the surface geologic map of France is from the OneGeology Europe Project.

Layer from Malte, 4 years, 11 months ago

The dataset consists of 87Sr/86Sr isotope ratios of plant samples and soil leachates covering the major geologic regions of France. In addition to the isotope data it provides the spatial context for each sample, including background geology, field observations and soil descriptions. The dataset can be used to create Sr isoscapes for France. Citation: Willmes M, Mcmorrow L, Kinsley L, et al.
