摘　　要：开合构造方式是开合构造学中的一项重要要素,涉及开合构造动力学。开合构造方式可根据开裂带和聚合带的形态和方向性,以及扩张应力与挤压应力之间的相互关系分为平行式、斜交式、剪刀式和夹子式。夹子式开合方式是本文首次提出的,故举蒙古-鄂霍次克中生代岩浆岩带和华南晚前寒武纪构造2个典型例子予以较详论述。The opening-closing pattern is an important element in opening-closing tectonics and concerns the opening-closing tectonic dynamics.According to the shapes and directions of opening and closing zones and mutual relation of extensional stress and compressive stress,the opening-closing patterns may fall into four types:parallel,oblique,scissors and clip movements.The last pattern is first proposed by this paper and has great significance.So taking for example the Mongol-Okhotsk Mesozoic tectonomagmatic belt and the Late Precambrian tectonics of South China,it is elucidated in more detail.
