U-Pb age and geochemistry of zircon from mantle xenoliths of the Katoka and Kat-115 kimberlitic pipes (Republic of Angola)

The Katoka and KAT 115 kimberlitic pipes are located on the ancient Archean Kasai Shield (North eastern Angola). The Katoka pipe has a complex geo logical structure and is characterized by significant variability of the rocks [1, 2]. The UPb age of zircon from kimberlite is 118 Ma
