Petrography descriptions and U-Pb zircon datasets from the Archean Pavas Block, Precambrian of Uruguay

Abstract

This database is a geological and geochronological compila- tion made to study a small Archean/Paleoproterozoic block located in the centre of the Precambrian rock exposition of Uruguay. Petrographic and field outcrops data supporting the samples from which the zircons for textural analysis and U-Pb dating (LA-ICP-MS) come are presented at first with their descriptions. The first table (1) contains the new U- Pb isotopic data. The second table (2) presents a correlation of textures from different zircon samples. The last table (3) contains an inventory of different U-Pb ages found in an- tecedents. All these data are associated with the paper en- titled: “The Archean Pavas Block in Uruguay: extension and tectonic evolution based on LA-ICP-MS U-Pb ages and air- borne geophysics".
