Dynamic effect of traps on kimberlites: identification of kimberlite klippen

Abstract

Vigorous dynamic activity of trap bodies was reported for the Alakit-Markha kimberlite field (Yakutia). This activity is illustrated by the displacement of the Lower and Upper Paleozoic blocks of sedimentary rocks and kimberlites, both horizontal and vertical. The amplitude of these displacements depends upon the morphology of trap bodies, their thickness, and is equal to 180 m and more (the full thickness of sill) vertically and several hundreds meter along strike.
