【摘要】 正确理解亚东—东巧—葫芦湖构造带的形成与属性对深化认识青藏高原的地壳形变、物质运动的行为与轨迹和深层动力过程极为重要.通过较系统的多元要素分析和研究发现:(1)基于壳、幔结构的空间展布特征表明,这是一条在EW向拉张力系作用下的陆内裂谷带;(2)强烈地震的活动与发生、大地热流异常值展布和地幔对流应力场研究证明,它是一条现今活动的大陆裂谷带;(3)该裂谷带的形成与演化乃地球内部物质与能量强烈交换的产物.更多还原

【Abstract】 The characteristics and formation of the Yadong-Dongqiao-Huluhu Belt(YDHB)are important to the understanding of crustal deformation,material movement and deep dynamics of the Tibetan Plateau.Analyses on multiple elements suggests that:(1)The YDHB is an intracontinental rift under EW-directed extensional force as evidenced by spatial distribution of crust and mantle structures;(2)High seismicity,distribution of abnormal terrestrial heat flow and the stress field by mantle convection indicate that it is an active continental rift;(3)The formation and evolution of the YDHB is the product of intense exchange of material and energy in the Earth′s interiors.更多还原
