摘要: Abstract The Rei Bouba Group is a sedimentary and volcanic sequence (750–?650 Ma), regarded as remnant of Pan-African (back-arc?) orogenic basin that separated remobilized Paleoproterozoic crust from an accretionary area (Poli Complex: 800-650 Ma). latter was subjected to early deformation (D1) intruded by calc-alkalic plutons (670 Transpressive tectonics major thrusting, with emplacement synkinematic granite, occurred at ca 630 Ma (D2-3) late compression (D4), 570 Ma.
