The role of plicative structures as forecast criteria in the Alakit-Мarkhinsky field (western Yakutia)

Abstract

This paper describes the tectonic features of the Alakit-Markha kimberlite field, regional factors of kimberlite magmatism control in this area, structural and tectonic preconditions for kimberlite pipe prospecting. The paper highlights kimberlite pipe formation features and the
role of tectonics in this process. The most promising areas are those related to low-amplitude negative structures
(e.g. depressions), especially transverse low-amplitude
complications of the opposite sign for the main plicative
structure: for antiforms (elevations), these are saddle-shaped depressions, and antiform elevations are for synforms
(depressions).
