| 摘 要： | 库车坳陷西段古近系库姆格列木群中分布着巨厚的盐岩层,喜山末期构造运动使得大量的盐体在库车前陆褶皱冲断带前缘被逆冲推覆至地表,遭受大气降水的溶解.除了平衡剖面恢复所得出的缩短量之外,盐推覆构造的逆冲推覆距离还应包括溶解盐体的厚度.通过采集研究区出露地表的盐岩样品,进行溶解物理模拟实验,估算自1.64Ma以来,研究区出露盐体的溶解厚度为3.969~14.727km.根据前人利用平衡剖面恢复所计算出该区的盐推覆构造的最大推覆距离为30km以上,从而得出该区的盐推覆构造的最大推覆距离为44.727km以上.

| Abstract: | There are many thick salt layers in Kumugeliemu group,Eogene,in Kuche Depression.A lot of salt bodies thrust up to ground surface in the frontal edge of the fold-thrust belt of Kuche foreland during late Himalayan,and experienced dissolution of meteoric water.Except for the shortening amount derived from balanced cross-section restoration,the thrusting displacement of salt nappes should include the thicknesses of the dissolved salt bodies.Through the solutional physical modeling of salt samples collected from the outcrops of the studied area,we estimate the thickness of dissolved salt bodies exposed in the studid area to be 3.969~14.727 km.The maximal thrusting displacement of the salt nappes has been estimated to be more than 30 km by former balanced cross-section restoration.We suggest that the maximal thrusting displacement of salt nappes of this area should be more than 44.727 km. |
