峨眉山玄武岩与台状山地地貌

On Mount Emei Basalt and Platform Mountain Landform

广泛分布于云、贵、川三省的二叠纪至三叠纪的峨眉山玄武岩是我国唯一被国际学术界认可的大火成岩省。其中,晚二叠世地幔柱活动喷发形成的峨眉山玄武岩面积达26万km2,形成了风光旖旎多彩地貌,是国内潜在的宝贵旅游资源之一。其中扬子板块西沿陆相喷发的“厚层”以钙碱性玄武岩、致密性和杏仁状构造玄武岩为主,形成了北起瓦屋山,南到大山包独特的桌山式玄武岩和斜台式玄武岩台状山地,是国内可贵的旅游地貌资源。在此,初步揭示峨眉山玄武岩台状地貌的特征,提出峨眉山玄武岩台状地貌在旅游资源的重要性,以期引起学者们对这一宝贵旅游资源的进一步研究与重视。

The Mount Emei basalt,widely distributed across the provinces of Yunnan,Guizhou,and Sichuan from the Permian to Triassic periods,is the only large igneous province internationally recognized by the academic community.Among these,the Mount Emei basalt formed by the eruption of the late Permian mantle plume covers an area of 260,000 square kilometers,creating a picturesque and colorful landscape that represents one of the potential valuable tourism resources in China.The"thick layer"of the Yangtze Craton's western continental eruption is predominantly composed of calc-alkaline basalt,dense and amygdaloidal textured basalt,forming a unique table mountain-style basalt and inclined platform-style basalt mountains ranging from Wawushan in the north to Dashanbao in the south,which are precious tourism geomorphological resources in China.This paper reveals the characteristics of the Mount Emei basalt's tableland topography and proposes the significance of this topography as a tourism resource,encouraging more focus and further research on this invaluable tourism resource.
