在远东,对亚洲大陆与太平洋接合带研究得比较详细。研究表明,接合带具有明显的地质特征,它是具有地槽和造山带特征的特殊“过渡型”岩系的分布区。在这些岩系中,淡水相粗粒煤系地层与较深海相硅-泥质沉积层互层。与后者共生的是基性火山和次透辉石组分的火山岩;以基性岩为主,其中发现有碱性岩、钙质—碱性岩和拉斑玄武岩变体。这种岩
In the Far East, the study of the convergence zone between the Asian continent and the Pacific has been more detailed. The study shows that the joint zone has obvious geological features, which is the distribution of special “transitional” rock series with the characteristics of troughs and orogenic belts. Among these rock series, the freshwater facies coarse-grained coal series interbedded with the deeper marine siliceous-muddy sedimentary layers. The symbiosis with the latter is volcanic rocks of basic volcanic and diopside components; basic rocks are mainly alkaline rocks, calc-alkaline rocks and tholeiite basalts. This rock
