| Résumé : | The porphyritic granite from the Luina dome (Shaba, Zaire) has been dated at 1882 +23/-19 Ma (U-Pb on zircon); it has also recorded an event at 526 ± 250 Ma. This late-Ubendian age can also be attributed to the granitic plutons of the whole Copperbelt. We propose to relate these granitic domes to the Bangweulu Block which here has been overthrusted by the Katangan sequence. Moreover, strontium isotopes show that the basement behaved as an open system during the Pan-African (=Lufilian) orogeny, a fact which must be taken into account when attempting to explain the genesis of the overlying Cu and U mineralizations. There is an abridged English version. -English summary |
