Post-collisional 1.75 Ga mantle-derived felsic magmatism in the Cauaburi Orogeny, NW Amazon Craton, Brazil

Post-collisional 1.75 Ga mantle-derived felsic magmatism in the Cauaburi Orogeny, NW Amazon Craton, Brazil

In the Amazon NW craton, ~1.75 Ga granites are commonly found inboard (eastern) the Cauaburi Magmatic Arc (1.81-1.76 Ga, flare-up phase), generated during the final stages of retreat of the arc westward, a process that lasted approximately 80 million years. This magmatism is more abundant in the No...
