These kimberlites are also the youngest kimberlites in the world by over thirty million years, cosmogenic helium-3 dates of olivine indicates they were erupted in the late Pleistocene-Holocene, [15] some indicated ages being 11,200 ± 7,800 ± and 12,400 ± 4,800. [3] A poorly constrained U-Pb date is 0 ± 29 million years. The cones display a ...
