Abstract

Kimberlites of the Alakit-Markha field formed in the middle Paleozoic and were repeatedly eroded over a long time period. Measured surface kimberlite erosion is compared with the reconstructed thickness of the host rocks, which includes sedimentary and igneous rocks of the Tunguska syneclise. The surface erosion of host rocks of individual kimberlites contradicts to their size and shape. Kimberlite formation features by stages are considered. The discrepancy between kimberlite size and shape, and volume of host rocks surface erosion is explained. The two-stage manifestation of the middle Paleozoic kimberlite formation is confirmed: late Silurian – early Devonian and late Devonian – early Carboniferous. Three sub-stages are distinguished in the last stage
