The Amazon Basin is a major sedimentary basin located roughly at the middle and lower course of the Amazon River, south the Guiana Shield and north of the Central Brazilian Shield. The basin develops on a rift that originated possibly about 550 million years ago during the Cambrian. Parts of the rift were reactivated during the opening of the South Atlantic.[1]
The basin has an elongate shape with a SWW-NEE orientation. It long axis runs from the vicinity of Manaus to the area near the confluence of Xingu River with the Amazon River.
