Abstract

Problems of the origin and tectonic structure of the South Verkhoyansk synclinorium are discussed. It is suggested that in the Late Paleozoic the South Verkhoyansk basin inherited the structure of the Sette-Daban rift graben arranged as a submarine valley across the Verkhoyansk passive margin. Lateral movements of the Okhotsk indenter during the Late Mesozoic orogenic events led to transformation of the South Verkhoyansk basin into the two-staged synclinorium of the same name, whose lower cleavage stage is an ore-bearing metamorphic layer.

South Verkhoyansk Synclinorium 构造结构的现代方面

摘要

讨论了南上扬斯克向斜层的成因和构造结构问题。推测晚古生代南维尔霍扬斯克盆地继承了塞特-达班裂谷地堑的构造，排列成横跨维尔霍扬斯克被动边缘的海底河谷。鄂霍次克压痕在晚中生代造山事件期间的横向运动导致南上扬斯克盆地转变为同名两级向斜层，其下劈理阶段为含矿变质层。
