萨马尔加古岛火山带为早白垩世古岛系,分布于锡霍特-阿林主复向斜东部。该火山带从马尔加里托夫卡河流域呈北东-南西向延伸,在图姆宁河流域则呈北东向延伸。萨马尔加带东南面为东锡霍特-阿林火山带的上白垩统地层所覆盖,它的北西界是东构造缝合线。萨马尔加古岛火山带的形成与锡霍特-阿林地槽区的最后发育阶段有关,当时本区在普遍抬升的背景上,其东南部分除有亚普第-阿尔必期的沉积作用外,还发生了活火山活动,从而在这里导致形成了巨厚的火山成因-沉积岩系的堆积。在锡霍特-阿林主复向斜内,在它与东锡
The Samar Gagud volcanic belt is of the Early Cretaceous Palaeoclines and is distributed in the eastern part of the Sikhot-Alin anticline. The volcanic belt extends northeast-southwest from the Togar River in the Margaritata, and extends north-east in the Tumen River basin. The Samarga belt is southeasternly covered by Upper Cretaceous strata of the East Sikhute-Arling volcanic belt, and its north-western boundary is the east structural suture. The formation of the Samarghoga volcanic belt was related to the last developmental stage of the Sikhot-Alhindi Slot. At the time of the general uplift in this area, in addition to the deposition of the Yapu-Al-Faisal, Active volcanic activity also took place, which led to the formation of a massive volcanic origin - the accumulation of sedimentary rocks. Within the synopsis of the Sikhhot-Alin, within it and East Tin
