青海省构造体系反映了青藏高原北部陆壳的形变特点。在长期构造应力作用下,青海构造体系逐渐形成了南北三分的应变格局:秦岭—昆仑东西复杂构造带横亘省区中部;青藏川滇歹字型构造头部独踞南侧半壁;昆仑以北则发育着一系列不同型式的扭动构造(祁吕贺兰山字型构造、河西系多字型构造、阿尔金山入字
The tectonic system of Qinghai Province reflects the deformation characteristics of the continental crust in the northern part of the Qinghai-Tibet Plateau. Under long-term tectonic stress, the Qinghai tectonic system gradually formed a north-south three-point strain pattern: the Qinling-Kunlun complex structural belt runs across the middle of the province; the Qinghai-Tibetan Sichuan-Yunnan-Zihe head has only one half of the south side in the south; Then developed a series of different types of twist structure (Qilu Helan mountain font structure, the Hexi Corps multi-font structure, Altun into the word
