红柳河蛇绿岩中的堆晶辉长岩层具有强烈的韧性变形现象．用 Ｔ Ｅ Ｍ 观察辉石的超显微位错组态特征，其自由位错从直线状、弓弯状、环状及具尖点、三结点结构直至漫散结构的胞结构，位错壁组态表现为由直线形和环形位错排列而成的两种类型，还可见清晰的亚颗粒构造．显微与超显微特征表明，辉石以晶内位错滑移为主导变形机制．利用动态重结晶的辉石－ 斜长石矿物对讨论了糜棱岩形成的温压条件：温度大约为４２０ ℃，压力１５０ Ｍ Ｐａ ；用动态重结晶颗粒大小对古差异应力进行估算，平均为８５ ．７８ Ｍ Ｐａ．认为红柳河辉长质糜棱岩是在洋盆扩张过程中，洋壳上部冷的刚性层与下伏较热的塑性层拆离，沿拆离面韧性剪切形成的．
The ductile gabbro in the Hongliuhe ophiolite has a strong ductile deformation. The super-microscopic dislocation configuration of pyroxene was characterized by T E M with free dislocations ranging from linear, bowed, ring-shaped and cusp-shaped, three-node structures to the bulk structure of diffuse structures, dislocations The wall configuration is characterized by two types of linear and ring dislocations, with clear sub-particle structures. The microscopic and ultra-microscopic features show that pyroxene is dominated by intramolecular dislocation slip. Based on the dynamic recrystallized pyroxene-plagioclase minerals, the temperature and pressure conditions of mylonite formation are discussed: the temperature is about 420 ℃ and the pressure is about 150 M Pa. The paleo-differential stress is estimated by dynamic recrystallization grain size with an average of 85. 78 M Pa. It is considered that the Hongliuhe gabbro is a detachment of the cold rigid layer above the oceanic crust and the underlying hot plastic layer during the oceanic basin expansion and is formed along the ductile shearing of the detachment plane.
