Magmatities of the Ebe-Khaya Dike Belt as a Possible Primary Source of Placer Diamonds in the Northeastern Part of the Siberian Platform

摘要

Along the periphery of ancient platforms (Africa, South America, Australia), some large alluvial diamond placer deposits with unknown primary sources of their origin are located [1, 2]. A similar situation is observed in the northeastern part of the Siberian platform in the Anabar River basin, where together with numerous nondiamond and diamond-poor kimberlite bodies there are Ebelyakh placers, unique in the resources and quality of diamonds [3, 4].
