| 摘 要： | 初步研究了西昆仑造山带广泛发育的一组ＮＷ—ＮＷＷ向拉伸线理的矿物组成、产状、分布层位等特征，探讨了其成因。认为该组线理为区内第三主变形期的“陆内榨挤”阶段导致西昆仑造山带逆冲推覆断层系被激发转变为大规模ＮＷ—ＮＷＷ向右旋平移走滑的产物。

| Abstract: | Preliminary studies have been undertaken on mineral types,attitudes and distributive strata of a well-developed NW-NWW-trending stretching lineation as well as its genesis. It is suggested that the lineation was developed along the thrust-nappe system which was transferred into a large-scale NW-NWW-trending dextral strike-slip fault during the intracontinental squeezing stage of the regional third main deformation phase in the western Kunlun orogenic belt |
