The main objective of this work was the study of magmatic and sedimentary environments associated to the rocks of the Neoproterozoic Tucuruí Group, and discusses their relation in the evolution of the Araguaia Belt. This unit is exposed in the region of Tucuruí, northeast state of Pará, northern Brazil, in transition zone between the Amazonian craton and Araguaia belt and is described as a volcano-sedimentary succession composed by basaltic volcanic deposits including occasional intrusions of diabase and basalt breccia intercalated with amalgamated arkosic arenite and siltstones interpreted as coastal deposits with layers oriented in the NNE-SSW dipping down to SE. The Tucuruí overthrusting fault affected this succession toward west, causin...
