摘　　要：陕西岚皋南宫山国家地质公园内火山岩形成于距今4.2亿年前的志留纪早期,是我国目前最古老的国家级火山岩地质遗迹保护区。公园以火山岩石峰林地貌和古火山岩崩塌地貌为特色,包括四大类、六类、七亚类地质遗迹资源。通过对南宫山地质公园内地质遗迹资源系统调查,采用定性与定量相结合的方法,进行了南宫山地质遗迹资源单体定量评价和综合价值评价。公园内国家级地质遗迹资源有4种,古火山岩石峰林地貌景观典型独特,具有秦巴地区志留纪火山岩建造的唯一性,具有重力崩塌地质作用过程遗迹的完整性,是区域地质历史演化研究的理想场所,是华南板块北缘晚加里东期裂谷构造活动特征的典型实例。Volcanic rock of Nangongshan National Geopark in Langao county of Shaanxi province formed in the Early Silurian dating back 42 million years ago,is the currently China＇s most ancient national volcanic geological relics protection zone. volcanic rock peak forest landform and ancient collapsed volcanic landform are the main features. There are four broad classes,six subclasses,and seven classes. Through the investigation on Nangongshan Geopark geological relic resources,we carried out quantitative evaluation and comprehensive value evaluation on Nangongshan geological relic resources by combination of qualitative and quantitative methods. In the park there are 4 kinds of national level geological relics. The ancient volcanic rock forest landform is typical and unique. with unique Silurian volcanic rocks construction in Qinba area,complete process of collapse relics by gravity,ideal research place of regional geological evolution and typical example of rift tectonic activity along the north margin of Southern China plate in late Caledonian.
