东南沿海大陆边缘剪切带是西太平洋活动大陆边缘构造带的组成部分,它是一条具有多次活动的左旋韧性平移剪切带。在本剪切带中可以观察到3种类型的构造:(1)规模巨大的呈北北东—北东向展布的糜棱岩带以及山拉伸线理组成的线状构造带。它们在平面上有明显的从断目两侧向中心递进变形特征;(2)呈北东走向陡倾角的糜棱叶理(Sa)、应变滑劈理或破劈理(Sb)、小型剪切带(Sc);(3)由西到东断层作用样式和断层岩具有明显的递进变化特点。西部(浅部)断层作用以脆性剪切滑动为主,其断层岩则由假玄武玻璃及镜面糜棱岩组成;中部断层作用以跪—韧性剪切为主,为断层泥—碎裂岩—超碎裂岩;东部(深部,以韧性剪切作用为主,其断层岩为暖棱岩—花岗糜桂片麻岩—眼球状糜棱岩系列。以上特点表明在本剪切带内透入性和非透入性变形之间有着密切的关系,反映出在变形过程中具有由韧性变形逐渐向脆性变形的发展趋势。

The Ailaoshan fault, regarded as an important boundary of tectonic units in western Yunnan (separating Cathaysia in the east from Gondwana in the west), is a large lithospheric fault developing progressively on the Precambrian oceanic crust. It exhibited strong subduction in the early stage of development before the Middle Jurassic to Early Cretaceous and gradually became ductile strike-slip shearing in nature from the end of Late Gre-taceou to Eocene and was basically a ductile strike-slip shear belt in the late stage fome the terminal Oligocene to Pliocene.The deformation structures in the Ailaoshan ductile strike-slip shear belt mainly include flow (and also fracture) cleavages, lineations and micro-folds.A series of microstructural evolution may be observed perpendicular to the direction of the shear belt which consists from northeast to southwest zones of dominant gneissic structure (granular mosaic texture), augen-like to flaser or phacoidal structures (porphro-clastic and other cataclastic textures) , schistose-folded structure (schistose to phyllonitic textures) and slaty -phyllitic structure (fine granoblastic to lepidoblastic textures). Of these, the zone of schistose-folded structure is the centre of the shear belt which exhibits the strongest plastic strain.The deformation structures and fabric evolution have shown that this belt is a dextral one. The main criteria for determining the shear direction are S-C fabric, folded (wavy)foliation, pressure shadow, rotationaJ porphyro-clasts and oblique extinction zones of crystals as well as echelon shear fractures.Theγ-X and ψ-X curves of the belt assume an irregular sine shape of which the highest peak value appears at the centre of the belt, with the shear strain γ=12.6 and the angle strain ψ = 85.5°, and the next highest peak appears near the Red River fault, with γ = 8 and ψ = 82.9°. The flow stress value and strain value obtained by calculation of dynamic recrystallized grains show the same regularity of changes, which are the greatest in the centre of the belt, being up to 389 MPa. Another high value appears near the Red River fault, being 224.5MPa. The shear belt has a cumulative displacement of about 53km.The calcite fabric shows that the Ailaoshan ductile shear belt underwent two stages of dextral strike-slip shearing.In the first stage, the principal compressive stress (σ1) was 3°/49° and the stress tensor -1.575, and in the second stage, 252°/1° and -0.876. It is estimated by referance to the regional geological information that the dextral shear stress originated from the lateral dextral shearing resulting from northward subduction of the Indian plate.In addition, the microstructures and stress field show that in the process of formation and evolution of the Ailaoshan shear belt there possibly existed a stage of sinistral strike-slip shearing, which was earlier than the dextral one.The study of the Ailaoshan ductile strike-slip shear belt also indicates that in the process of formation and evolution the Red River fault experen-ced dextral strike-slip shearing.
