【摘要】 鲜水河断裂带的断层破碎带在四川省炉霍县旦都一带发育成土(石)林构造。其原岩为中-上三叠统如年各岩群(一套含灰岩滑塌块体的火山-构造混杂岩地层单位)变质砂岩夹板岩,在再脆性变形机制下断裂破碎形成。其内发育一组倾角较缓的劈理构造,可能是重力与地震波联合作用的产物。其内的擦痕、阶步构造显示至少存在早期右行,晚期左行两个活动阶段,并且左行走滑常伴有逆冲分量。更多还原

【Abstract】 Earth pillars are well developed in Dandu,Luhuo in fractural zone of the Xianshuihe fracture zone.They were formed by brittle deformation from a metasandstone intercalated with slate of the Middle-Upper Triassic Runiange Group.Fault scratch and step structure indicates early right-lateral and late left-lateral strike-slip accompanied by thrust movement.更多还原
