摘要
本文以柳江盆地为研究对象,通过地质遗迹资源调查与评价工作,系统对柳江盆地内地质遗迹类型进行划分,总结其地质特征及分布规律,研究探讨其成因演化.本研究共在柳江盆地及周边发现重要地质遗迹点101处,可分为3大类,11类,22亚类,其中基础地质大类50处、地貌景观大类43处、地质灾害大类9处.地层剖面、古生物群化石产地等地质遗迹分布于向斜东翼低山和丘陵一带;褶皱与变形、断裂地质遗迹主要分布于向斜西翼;岩溶地貌、水体地貌多分布于盆地内河流两岸或地势低洼处;地质灾害大类地质遗迹点主要分布在黑山窑—上庄坨—义院口一带.华北地台多次抬升与沉降及由其引起的岩浆活动和构造运动造就了柳江盆地丰富的地质遗迹资源的形成.
Abstract
Based on the investigation and evaluation of the geo-heritages in the Liu River Basin,the types of geological remains in the Liu River basin are classified systematically,and their geological characteristics and distribution patterns are summarized,to study its origin and evolution.In this study,a total of 101 important geological sites were found in and around the Liu River basin.Among them,50 are basic geologic sites,43 are geomorphology and landscape sites,and 9 are geological disasters sites.The geological remains such as stratigraphic section and fossil origin of Palaeobiota are distributed in the low mountains and hills of the east flank of the syncline,and the geological remains of folds,deformation and faults are mainly distributed in the west flank of the syncline Karst landform and water landform are mostly distributed on both sides of rivers or in low-lying areas in the basin,and geological disasters are mainly distributed in Heishanyao-Shangzhuangtuo-Yiyuankou area.The uplift and subsidence of the North China Platform and the magmatic activity and tectonic movement caused by it have resulted in the formation of abundant geological relics resources in the Liu River basin.
