In this new article, the results of a study of high spatial precision dating using ionic microprobe of dykes of the southern São Francisco craton are presented. Mafic dykes are very important as they are excellent temporal and spatial markers of magmatic, tectonic and basin opening events. They usually form swarms of defined orientation thatContinuar lendo “MAGMATIC BARCODES HELP TO RECONSTRUCT ANCIENT SUPERCONTINENTS! / CÓDIGO DE BARRAS MAGMÁTICO AJUDA A RECONSTRUIR ANTIGOS SUPERCONTINENTES!”

THE AGE OF MOUNTAINS AND CONTINENTS FROM TINY MINERALS /A IDADE DAS MONTANHAS E DOS CONTINENTES EM PEQUENOS MINERAIS
Some minerals found in rocks are special in that they accommodate a lot of specific chemical elements in their structures and almost none of other elements. This is the case of zircon (ZrSiO4), which likes Uranium but allow almost no Lead in it’s structure. This turns zircon in an ideal mineral to calculate the ageContinuar lendo “THE AGE OF MOUNTAINS AND CONTINENTS FROM TINY MINERALS /A IDADE DAS MONTANHAS E DOS CONTINENTES EM PEQUENOS MINERAIS”
