Resumo

A barita é um mineral de ganga comum em sistemas hidrotermais de baixa temperatura. Na área do Seival, a cronologia relativa dos minerais indica que a barita, a calcita e a pouca hematita estão associadas aos estágios hidrotermais de baixa temperatura (< 157° C) de uma mineralização epitermal da Bacia do Camaquã, Cinturão Dom Feliciano, Neoproterozoico. Interpretações anteriores de dados geoquímicos sugeriram que o enriquecimento de Cu nos sulfetos está relacionado à albitização e à cloritização, mas não determinam as origens ou as condições de cristalização da barita. O conteúdo de Ba, S e suas condições de precipitação foram examinados e foi observado um conteúdo menor de Ba no plagioclásio alterado que possui composição de albita, do que na porção menos alterada que possui composição de andesina-labradorita. Além disso, a análise de elementos de terras raras (ETRs) de barita e plagioclásio sugere que a composição elementar da barita na área de Seival veio de material vulcânico (magmático) com influência de água meteórica em vez de água do mar. Os diferentes padrões de ETRs da barita mostram dois grupos relacionados a duas fontes magmáticas de ETRs. Essas diferentes fontes de S, Ba e ETRs foram interpretadas como alteração dominante de rochas vulcanogênicas locais, como rocha piroclástica e fluxos de lava andesítica ou, menos provavelmente, dique lamprofírico.
