山东省优势大地构造相划分初步方案

Primary Scheme on Division of Geotectonic Phases in Shandong Province

摘要:

大地构造相是反映陆块区、造山系和叠加造山-裂谷相系形成演变过程中的一套岩石构造组合，是表达大陆岩石圈板块经历离散、聚合、碰撞、造山等动力学和地质构造作用过程而形成的综合产物。根据优势大地构造相的划分原则与沉积岩、火山岩、侵入岩和变质岩建造构造等特征，山东大地构造相可划分为3个相系（Ⅰ级）、4个大相（Ⅱ级）、17个相（Ⅲ级）和51个亚相（Ⅳ级）。

Abstract:

Tectonic phase is a combination of rock structure which can reflect the formation and evolution process of land mass area, orogenic system and superimposed orogeny system. It is an integrated production formed by dynamics and geological tectonism of the continental lithospheric plate, such as discrete, aggregation, collision and orogeny. According to the division rule of superior tectonic facies and characteristics of sedimentary rocks, volcanic rocks, intrusive rocks and metamorphic rocks, tectonic phases in Shandong province can be divided into three phase systems (Ⅰ level), four major phases (Ⅱ level), 17 phases (Ⅲ level) and 51 sub-phases (Ⅳ level).
