Abstract
An Ediacaran complex of dyke rocks has been identified for the first time in the Yenisei Ridge orogen. These igneous rocks are represented by basic, intermediate and acid variants and formed in the conditions of the transform active continental margin at the stages of its development before and during the interruption of subduction and slab breakoff: from dykes of the picrodolerite - dolerite-quartz diorite - leucogranite association with age in the range of 626-623 Ma (U-Th-U isotope data for zircons, SHRIMP-II method, this work) up to adakite - gabbro-anorthosite magmatism at the end of the Ediacaran.
在叶尼塞岭造山带首次发现了埃迪卡拉纪岩脉杂岩。这些火成岩以基性、中性和酸性变异体为代表，形成于大陆边缘在俯冲和板块断裂中断之前和期间的转化活动发育阶段的条件下。从年龄在626-623 Ma (SHRIMP-II方法中锆石的U-Th-U同位素数据)范围内的微白云岩-白云岩-石英闪长岩-浅花岗岩脉，到埃迪卡拉纪末期的埃克岩-辉长岩-斜长岩岩浆作用。
