The Boundaries of the West African Craton - Special Publication no 297 (Geological Society Special Publication)Publisher: Geological Society of London edition 2008 PDF 536 pages 18,7 mb
The boundaries of rigid cratons can be affected by subsequent orogenic events, leading to 'metacratonic' characteristics not often properly recognized and still poorly understood. Major lithospheric thickening is absent and early events such as ophiolites are preserved; however, metacratonic boundaries are affected by major shear zones, abundant magmatism and mineralizations, and local high-pressure metamorphism.
