| 摘 要： | 文章通过对河流阶地、溶洞及断裂地震活动的研究,认为南宁市自新生代第四纪以来,一直处于持续抬升状态,而交替出现较短的稳定期.晚更新世至全新世,抬升速度减缓,稳定时间增长,而且在总体抬升的背景上,出现了沉降运动.由于该区处于区域性大断裂包围之中,属较稳定地块,断裂和地震活动虽较频繁,但强度较小,近期内不会造成较大的破坏性.

| Abstract: | In this paper, based on the study of river terrace, karst grotto, fault and earthquake, The auther considers that the crust in Nanning city has been uplifting since Quaternary period. The crust uplifted for a long time and stabilized for a short time in palaopeistocene and Middlepleistocene.The speed of uplift became slow,and the period of stability became long from Neopleistocene to Holocene epoch .There were descending movement on the uplift background in Holocene epoch.This area is surrounded by regional fault,and belongs to stability block.The activities of fault and earthquake are frequent in this bloke,but the strength is weak.So it will not preduce terrible destruction in recent time. |
