Monazite U-Pb dating and 40 Ar- 39 Ar thermochronology of metamorphic events in the Central African Copperbelt during the Pan-African Lufilian Orogeny

Rainaud, C.; Master, S; Armstrong, Richard; Phillips, David; Robb, L

Description

New SHRIMP U-Pb age data on metamorphic monazite, as well as step-heating 40Ar-39Ar ages on metamorphic biotite, muscovite and microcline, from Katangan metasedimentary rocks of the Central African Copperbelt are presented. These rocks were deformed and metamorphosed during the Pan-African Lufilian Orogeny. Three samples of metamorphic monazite from the Chambishi structural basin give ages of 592 ± 22 Ma, 531 ± 12 Ma and 512 ± 17 Ma, which correspond respectively to the ages of eclogite facies...[Show more]
