长春市南湖-桑家窝堡断层特征及活动性研究
|
摘要
南湖—桑家窝堡断层是一条穿越长春市区的北西向隐伏活动断层,该断层对长春地区的地壳稳定性影响较大。利用高分辨率遥感信息解译、探地雷达探测、浅层人工地震勘探和钻孔联合剖面探测等资料,并结合第四纪沉积物的ESR年龄测定资料,讨论了南湖—桑家窝堡断层的空间展布和运动特征。南湖—桑家窝堡断层沿逯家窝堡、后三家子、南湖公园、长春公园、桑家窝堡、大合隆一线展布,断层产状为45°∠65°,断层线较平直。在断层西北端大合隆一带,南湖—桑家窝堡断层错断了上白垩统嫩江组(K2n)岩层,并在嫩江组岩层顶部沿断层形成了侵蚀沟谷,但没有错断早更新世和中更新世地层。在断层东南端的逯家窝堡附近,南湖—桑家窝堡断层错断了白垩纪泉头组(Kq)岩层,但没有错断中更新世和晚更新世地层。南湖—桑家窝堡断层形成于中生代末期,第四纪早期曾经活动,活动方式以左旋走滑运动为主,第四纪中更新世以来断层没有明显的活动迹象。
Nanhu-Sangjiawopu Fault is a buried active fault striking in northwest and crossing Changchun City.It is very important to the crust stability of Changchun district.Based on the data of high-resolution remote sensing information interpretation,ground penetrating radar probing,shallow seismic investigation and exploration of composite drilling section and the data of ESR dating for Quaternary deposits,we discuss the spacial distribution and active characteristics of Nanhu-Sangjiawopu Fault.Nanhu-Sangjiawopu Fault is with a straight fault trace extends along Lujiawopu,Housanjiazi,Nanhu park,Changchun park,Sangjiawopu and Dahelong.Its occurrence is 45° ∠65°.At Dahelong village in the northwest segment of the fault,it displaced the strata of Upper Cretaceous Nenjiang Formation leaving a eroded gully along the fault trace at the top of the Nenjiang Formation but displaced the strata of Early and Middle Pleistocene.Near Lujiawopu in the southeast segment of the fault,it displaced the strata of Cretaceous Quantou Formation but displaced the strata of Middle and Late Pleistocene.Nanhu-Sangjiawopu Fault was formed in the end of Mesozoic and became active as a left-lateral slip fault in Early Quaternary.It has not acted since Middle Pleistocene.
