Precious zircon and corundum megacrysts, occurring in palaeochannels and palaeoterraces around Cenozoic volcanic rocks outcropping within an area of 20 km2. The rock types include limburgite, olivine basalt, pyroxene-olivine basalt, andesitic basalt, and minor tholeiite. They contain abundant mantle xenoliths of garnet lherzolite, spinel lherzolite and garnet pyroxenite.
