A new kimberlite body in the Alakit-Markhinsky field – Morozov tube

The article provides general information about the Alakite-Markha kimberlite field (AMCP) The Yakut diamondbearing province (YAP). New results are presented concerning the features of the tectonic structure of the AMCP, which influences the choice of methods used to search for kimberlite bodies. The history of the discovery of the Morozov tube is shown, which was accomplished due to the timely positive implementation of the acquired methodological, mainly structural-tectonic and geological-mineralogical techniques for searching for kimberlite bodies in geological sections saturated with traps. A characteristic is given and a description of this technique is presented, based on the developed search features and prerequisites, the use of which led to the discovery of a new kimberlite pipe. The main prerequisites (structural-tectonic, stratigraphic, mineralogical, and lithological) and search features (geophysical anomalies, kimberlite bodies, near-ore changes, and ore halos of indicator minerals) are shown. The geological structure and morphology of the new kimberlite body are characterized, its position relative to the enclosing and overlapping sediments is shown, the morphology and description of the internal structure of the kimberlite body are characterized. The first results of studying the material composition (mineralogy, petrography, geochemistry) of various rock complexes of the new kimberlite body and a detailed description of the indicator minerals contained therein are presented. Using the example of the AMCP, the correctness of the methodological approach used to search for kimberlite bodies in closed territories saturated with traps is shown. It is emphasized that the identification of a new kimberlite body of significant size in a well-studied area with a high density of the exploration drilling network indicates the high residual prospects of the Alakit-Markha kimberlite field for the identification of new diamond deposits. we express our gratitude to R.F.
