Abstract
Study of faults and secondary mineralization of host rocks of diamond-bearing kimberlites yields important data for local prediction of kimberlite bodies. Of special methodological interest are exploration data on deposits where the study of host rocks is based on a dense observation network. Factual material for this paper was collected from cores of all inclined exploration boreholes of the Maiskoe diamond deposit found in the Nakyn field in Yakutia in 2006. The paper shows a nonuniform distribution of tectonic deformations, stringer mineralization, O and C isotopes of calcite, and CO2 content of Lower Paleozoic host carbonate rocks of kimberlites. Our data agree with different diamond potentials of two areas of the Maiskoe kimberlite body, which can be used to search for and explore deposits.
