Abstract
In according with interpreting gravity and magnetic fields the structure of the Northern Part Yakutian diamond province crystalline basement presents as Olenek and Nakian Archean cratons, which separated Late Proterozoic Anabar-Lena mobile belt. Description are given of the inner structure of the Anabar-Lena mobile belt as two segments, Daldian and Khapchan, which separated Billiakh tectonic zone. In according with the investigation, Mesozoic kimberlite magmatism situated in the Khapchan segment of the Anabar-Lena mobile belt, on the other hand Paleozoic kimberlite magmatism situated in the Olenek Archean craton.
