  "description": "This dataset consists of seven lava samples that were analyzed for Pb, Sr, and Nd isotopes.  The dataset accompanies the planned publication, ‘The geochemical and petrogenetic evolution of Þingmúli central volcano:  Insights to magma processes in Iceland’, as well as planned future publications on this volcanic complex.  Pb, Sr, and Nd isotope data were used for this study to determine both the mantle source, and the relationship between the lavas (rhyolite to basalt) found at Þingmúli.  Samples were collected from Þingmúli central volcano by Amanda Hughes (Edge Hill University, UK) who sent them to the USGS Denver for analysis. The laboratory work and thermal ionization mass spectrometry (TIMS) analyses were performed from April 2024 to Oct 2024.",
