文摘

Juruena orogen took place in SW Amazonian craton between 1.81 and 1.51 Ga. Is a accretionary orogen with E-W trend about 1100 km long and 350 km wide. The orogen includes Jamari and Juruena terranes, products of long-lived convergence. The orogen has been the site of two orogenic reativation in the Mesoproterozoic. It is relevant to establish of the Amazonian craton in the Columbia supercontinent.
