Figure 9.7. Statistics on diamond morphologies associated with different kimberlite pipes in Siberia. The areas with vertical lines represent an octahedral morphology with only a slight dissolution those with the circles show crystals bounded by curved faces, which received heavier dissolution. Blank areas correspond to an intermediate type.

Fig. 2. Schematic map showing mean redepletion model ages determined for peridotite nodules from kimberlite pipes erupted in southern Africa. Cratonic regions are outlined in yellow, the Limpopo Belt in brown. Solid coloured circles indicate individual kimberlite pipes from which several xenoliths have been analysed.

A diamond bearing kimberlite pipe was discovered in Siberia in 1954. There are at least 300 kimberlite pipes in Siberia. The most productive of these is the Udachnaya mine near the town of Udachnaya.
