摘要
威远穹隆是四川盆地内一个陡然凸起的穹状背斜,在地貌上形成以砂岩方山群为特征的穹状山体。背斜核部出露了含煤岩系和铁矿层,天然气在背斜中聚集形成了著名的威远气田;还孕育了方山古寨群、地质学研究遗址、矿产采冶遗址等历史文化景观。这些丰富的自然与文化遗产,为该区域的经济结构调整、地质公园建设与旅游发展提供了重要基础条件。
The Weiyuan dome is a suddenly bulge quaquaversal anticline in the Slchuan basra, geomorphologically forming a domal moumain characterized by sandstone mesa group. Coal-bearing series and iron ore beds are exposed in the core of the anticline. The famous Weiyuan gas field was formed in the anticline. Ancient mesa strongholds, geoheritage, mining and metallurgical sites are scattered within the boundary of the dome. All these abundant natural and cultural heritages lay a foundation for readjustment of economic structure, geopark construction and tourism development in this region.
