The Guéra Massif of South-Central Chad is composed of collisional and post-collisional intrusive rocks related to the Central African Orogenic Belt. Collisional granites were emplaced at 595-590 Ma but there are a series of post-collisional intrusions that were emplaced at 570-560 Ma. The older gran...
