Abstract

This paper presents the description of the structural-tectonic prospecting criteria of kimberlite bodies which are among the most important ones for the Alakit-Markha kimberlite field. The key criteria elements determining the kimberlite fields’ structure and kimberlite bodies’ location are dislocations with a break in continuity of various orders.
The most prospective areas considered are those where multidirectional dislocations with a break in continuity make up tectonic knots associated with the contrast diamond indicator mineral (DIM) dispersion haloes. The paper also de- scribes the methods that are used for disjunctive dislocations mapping and cites the list of ore-bearing faults as well as patterns of kimberlite bodies’ location within their bounds.
