| 摘 要： | 根据褶皱形成的运动学特征,对膝折带迁移、翼部旋转和混合生长3种模式的沉积与抬升关系进行探讨,并针对3种褶皱发育模式提出利用生长地层厚度推测褶皱抬升速率与褶皱过程的方法.研究表明:以膝折带迁移为变形机制的褶皱,发育过程中翼部倾角不变,褶皱顶部与翼部的抬升速率相同,形成翼部平行状生长地层;以翼部旋转为变形机制的褶皱,发育过程中翼部长度不变,沿翼部各点的抬升速率呈线性变化,形成翼部楔状的生长地层;以混合生长为变形机制的褶皱,发育过程中翼长和翼部倾角都发生变化,部分生长地层呈平行状,反映了膝折带迁移的特征,部分生长地层呈楔状,各点的抬升速率仍呈线性变化,反映了翼部旋转的特征.

| Abstract: | Based on the kinematics characteristics of fold forming,the relationship between sedimentation and uplift of three kinds of models including hinge migration,limb rotation and hinge migration with limb rotation was discussed. According to three kinds of development models of fold,a method was proposed to calculate fold uplift rate and folding process using the thickness of growth strata. The results show that the limb dip angle of fold developed by hinge migration keeps constant,and the fold has the same upl... |
