The H. Ode theory indicates that a relation of stress-strain may begained by the differentiation with a plastic medium due to the velocitydiscontinuity in plastic deformation. Thus the medium can glide a long thecharacteristic planes with slab-smooth, and a ductile shearing de forma-tion may occur there. On the basis of researches in two examples andthree experiments, the Ode theory has been expounded and discussed, andthe forming conditions, the moving mechanism and the mechanic featureshave also been analysed....

H.O de理论认为,塑性变形存在着速度不连续,介质可沿其速度相同的平滑面发生韧性剪切变形。本文通过两个实例和三个实验的观察研究,对该理论进行了初步的阐述和探讨。

The orogeny of Dabie mountain was resulted from collision between the North China and Yangzi massifs in early Mesozoic. The tectonic evolution of Dabic orogenic bolt underwent two stages. The intcrfomational sliding and shearing appeared in Indosinian movement. Thrusts and tcnsional structure occurred in southern and northern parts of Dabic orogeny separately, when hot-uplift formed in Yanshan movment. Three tectonic belts can be divided in the orogeny of Dabic mountain: the Nanhuaiyang thrust belt, Dabic upheaval...

大别山在中生代时期的造山运动是由于华北地块和扬子地块继晚元古代之后再次发生碰撞活动而发生的。造山运动经历了两个阶段:印支期自北向南的推挤,形成韧性剪切变形和逆冲断层系;燕山期出现以中、酸性岩浆活动为背景的构造隆起,在北淮阳形成盆岭构造带。

This paper deals with the ductile shear zones and their deformed rocks in the crust and upper mantle. In most cases, the deformed rocks within ductile shear zones are my-lonites, because rock grain size obviously reduced and strengthening foliation (lineation) developed. In some cases, however, when aphanitic limestone or feldspar-rich rocks undergo ductile shearing, the deformed rocks within shear zones show local increase of rock grain size or no remarkable grain size reduction. They are not typica Imylonites....

This paper deals with the ductile shear zones and their deformed rocks in the crust and upper mantle. In most cases, the deformed rocks within ductile shear zones are my-lonites, because rock grain size obviously reduced and strengthening foliation (lineation) developed. In some cases, however, when aphanitic limestone or feldspar-rich rocks undergo ductile shearing, the deformed rocks within shear zones show local increase of rock grain size or no remarkable grain size reduction. They are not typica Imylonites. It is evident that the deformation products of rocks within the shear zones are differernt due to different deformation condition, deformation medium and deformation mechanism.

本文讨论了地壳和上地幔中韧性剪切带及其中的变形岩石。在大多数情况下,韧性剪切带中的变形岩石为糜棱岩,因为经受韧性剪切变形时,岩石的粒度显著减小并发育了强化的叶理(线理)。但是在某些情况下,例如,当隐晶质灰岩及富含长石的岩石经受韧性剪切变形时,剪切带中的变形岩石粒度局部增大或者没有发生明显减小,它们并不是典型的糜棱岩。由于变形环境、变形介质及变形机制的不同,韧性剪切带内岩石变形的产物是不同的。
