The middle granodiorite in the Luolei Copper district, Roshipina area, Namibia, intruded in the Orange group (quartz- mica schist). The 206Pb/238U weighted age of magmatic zircons from the granodiorite intrusion is 1875. 1±3. 8 Ma(n=21，MSWD=0. 59), which suggests that the magma was formed in the Paleoproterozoic, and was part of the magmatism during in the Amazon orogeny process. The 10 tested samples from the middle granodiorite intrusion in the Luolei Copper district are from peraluminous rocks, which exhibit the geochemical characteristics of enriched LREE, depleted HREE, and display distinctly negative Eu anomaly. The geochemical characteristics of the middle granodiorite intrusion in the Luolei district suggest it is an I- type granitoid, and the magma was derived from the mixing of the lower crust and upper mantle sources, and experienced distinct fractional crystallization during its emplacement. Moreover, the whole- rock geochemical features indicate the middle granodiorite intrusion is Cu- rich granitoid, which is the ore- forming intrusion of the Luolei Copper deposit. Combining the geology, geochronology and geochemistry characteristics, we conclude that the middle granodiorite intrusion related the Cu mineralization in the Luolei district was formed within a post- collisional background.
