山东省构造体系的成生发展历史

GENERATION AND DEVELOPMENT HISTORY OF THE STRUCTURAL SYSTEMS IN SHANDONG

摘要:

本文用地质力学的观点,以构造体系的成生发展过程来反映山东地质发展历史,分别叙述了每个地质年代内,山东所处的构造应力场,各种构造体系的活动方式,以及它们活动所控制的沉积和岩浆活动。太古代至古生代山东主要受到了东西向构造体系的控制,形成了基底“地槽”和“地台”盖层。中生代以来主要受到了新华夏系的控制,此外尚有东西向构造和南北向构造体系的活动。在新华夏系活动的同时,还分别派生了一些大型的帚状构造、“S”型构造、入字型构造等。上述这些构造体系的成生发展过程,形成了许多拗陷、凹陷、断裂、褶皱等结构面;沿着断裂还侵入有岩浆,形成大小不等的各种岩体;同时控制形成了各种内生和外生矿产;在一些地方各种不同的构造体系还发生了联合和复合作用。新生代,尤其是新构造活动,各种构造体系的活动还控制了现代山川形势和地层及岩体的展布。

Abstract:

From a standpoint of geomechanics, the paper depicts the geological development history of Shandong by showing the generation and development of its structural systems. Seperately, the structural stress fields Shandong was in, the activity modes of the various tectonic systems, and the sedimentary and volcanic activities under their control in each geological time were addressed.From the Archaean to the Palaeozoic, Shandong was controlled predominantly by the E-W extending structural systems, and the baseme...
