初论开合构造方式

On opening-closing patterns

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。

Abstract: 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 compressi
