| dc.description | Orogenic bending, extension during orogenic convergence and tectonic control of Cu-dominated mineral remobilisation are well illustrated in the Pan-African Lufilian Arc and its Kundelungu foreland (Katanga, DRC). A fault-kinematic analysis and paleostress inversion of brittle structures at 19 mine sites covering the entire area has been performed. The 63 stress tensors obtained, representing 1444 fault-slip data have been grouped into 8 stress stages spanning the brittle tectonic evolution since the Lufilian orogenic climax: Lufilian compressional climax (stage 1), orogenic bending (stage 2), strike-slip deformation (stages 3-4), late-orogenic arc-parallel extension (stage 5), post-Lufilian, early Mesozoic transpressional inversion (stage 6) and Meso-Cenozoic, rift-related extension related to the Tanganyika trend (stage 7) and to the Moero trend (stage 8). Remobilisation, generating vein-type ore deposits, only occurred during the strike-slip to extensional stress stages (2-5, 7-8), while the compressional stages (1, 6) did not caused reworking of the ore deposits. | |
