Abstract
The discovery of kimberlite pipes containing diamonds in the Viluy-Markha dyke belt led to a surge in interest in studying the products of Middle Paleozoic basic magmatism associated with these pipes in terms of their spatial and temporal characteristics. A distinct group of high-titanium rocks linked to diamond-bearing kimberlites was identified among the basic intrusions, serving as a key indicator for locating kimberlite pipes. This discovery prompted further research on basites and potential areas, such as the northeastern region of the dyke belt within the Muno-Tunga interfluve region, where alluvial diamonds have been found but their original sources remain unidentified. The presence ofdiamond varieties typical of kimberlites with high diamond concentrations in the placer diamonds of this area suggests the possibility of a new kimberlite field. The study of Middle Paleozoic basites in the Muno-Tunga interfluve region revealed high-titanium basites with similar petrochemical characteristics to those associated with diamond-bearing kimberlites. These basites are situated on the flanks of the dyke belt marked by compensating compression, making them a promising indicator for kimberlite prospecting. This study has demonstrated that areas with preferential compression are highly prospective for identifying primary diamond deposits.
Supporting agencies: This study was conducted as part of the research plan for the DPMGI SB RAS “Mantle magmatism, lithosphere evolution and ore content of the eastern part of the Siberian platform, geoecology of subsurface use” (No. FUFG-2024-0007).
