Archean crust and metallogenic zones in the Amazonian Craton sensed by satellite gravity data

This is the geochronology data inventory for the published paper 'Archean crust and metallogenic zones in the Amazonian Craton sensed by satellite gravity data' on Scientific Reports.

As it reads in the Methods section of the publication: ' Geochronological data.To constrain our interpretations over the physical structure of the terranes regard-ing feasible geological evolution, we evaluated their age relationships from a compiled geochronology data set. We examined the TDM model and crystallization ages to unveil the relationships of parent material to a common ancestor reservoir, and crystallization of igneous and protoliths rocks, respectively. Evaluation of εNd determi-nations provide clues for the derivation of crustal material during crystallization and reworking episodes. The compiled data set comprises 414 age determinations from various minerals and methods (Sm-Nd, U-Pb, Pb-Pb, K-Ar, Ar-Ar isotopic systems). The target ages were model (n = 142) and crystallization (n = 272) ages. A total of 99 simultaneous determinations of Sm and Nd isotopic composition and crystallization ages with εNd calcula-tions were compiled to evaluate crustal evolution. Data come from more than 50 publications, most of them cited in papers14–18,21,22,26,28,30,31,33–35,42,50 and references therein. We are aware that the geochronology data set is deficient in some aspects, such as the existence of geographical gaps (e.g., western Carajás, southern Bacajá), sample collec-tion bias, and preservation of the geochronology record, or even incomplete inspection of the record'.
