چکیده انگلیسی
The accretion of the Pan-African Anti-Atlas belt to the West African super continent (WAC) was a four-stage event, involving extension, subduction, moderate collision and extension. The calc-alkaline magmatism of the subduction stage was associated with large-scale base metal and gold mineralisation. Metallogenic activity was greatest during the final extensional stage, at the Precambrian-Cambrian boundary. It is characterised by world-class precious metal deposits, base-metal porphyry and SEDEX-type occurrences.
