Icelandic Volcanic Rocks Isotopic Database (IVID) ...

We compile a new geochemical database (Icelandic Volcanic rocks Isotopic Database, IVID) which includes previously reported 87Sr/86Sr, 143Nd/144Nd, 176Hf/177Hf, 206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb, 187Os/188Os and 3He/4He data and major and trace element concentrations measured in Icelandic volcan...

Description
Summary:We compile a new geochemical database (Icelandic Volcanic rocks Isotopic Database, IVID) which includes previously reported 87Sr/86Sr, 143Nd/144Nd, 176Hf/177Hf, 206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb, 187Os/188Os and 3He/4He data and major and trace element concentrations measured in Icelandic volcanic rocks. Isotopic compositions were evaluated, and filtered to identify the highest quality data and data most likely to represent mantle-derived compositions. The carefully filtered, comprehensive geochemical database is an important contribution to the geochemical community and can be used to put further constraints on the generation of geochemical heterogeneity in Iceland. We use the compiled database to examine the spatial distribution of geochemical components in the Icelandic mantle, and test whether melting processes control how source heterogeneity from the deep mantle is extracted on the surface. The PRIMELT software (which combines an inverse model for crystallization in the crust with a forward model ...
