| 摘 要： | 西藏班戈地区的遥感地质调查研究表明:该区发育菱形网结状构造;错那、东错、蓬错、巴木错呈明显的"多字形"斜列,应为统一应力场下形成的伸展断陷盆地,并受到后期右行活动破坏;在东卡错-东错菱形块体中央隆起内发现有较大规模的岩浆岩侵入,推测该隆起区下为一地幔热柱;由北向南出露有东巧蛇绿岩带、东错-蓬错蛇绿岩带、白拉-觉翁蛇绿岩...

| Abstract: | Investigation of remote sensing geology shows that rhombic anastomosing structure is developed and Cuona,Dongcuo,Pengcuo,Ba Mucuo are distributed in xi-type struoturd system en echelon in Bange area of Tibet.They should be extensional fault basins formed under the same stress field and exposed to later right lateral shear.Large magmatic body intruded in central dome of Dong Kacuo-Dong Cuo lozenge rhombic block suggesting that under the dome occurs a mantle plume.From north to south are exposed intermitently... |
