Аннотация

The article describes the indicator minerals of kimberlites from the tuffs of the Tunguska syneclise. Two types of them are distinguished: one corresponds to the eluvium of kimberlite, the second has "signs of antiquity" corresponding to kimberlite minerals from the Upper Paleozoic reservoirs associated with the Middle Paleozoic kimberlites. Most likely, the minerals of the first type are associated with the local Late Jurassic kimberlite body that cuts through the rocks of the trap formation of the Tunguska syneclise, the minerals of the second type are captured from an intermediate sedimentary reservoir, probably of the Upper Paleozoic age. Thus, there is reason to assume the existence of Mesozoic kimberlite bodies intruding the rocks of the trap formation of the Tunguska syneclise, as well as the existence of Middle Paleozoic kimberlite bodies, including diamond-bearing ones, under the syneclise traps.
