摘要
雁荡山地质遗迹为白垩纪复活型破火山。本文试从全球火山(岩)带同类地质遗迹的 视域考量雁荡山地质遗迹的科学价值。雁荡山是亚洲大陆边缘巨型火山岩带中白垩纪破火山 的典型代表,它涵盖了流纹质火山作用各类产物,是流纹质火山岩的天然博物馆,是研究亚洲大 陆边缘构造与岩浆作用的天然窗口。杰出的科学价值与优秀奇特的自然美景与浓厚山水文化, 三者融于雁荡山一体,实属世界罕见。
The Yandangshan Geologic Heritage is a Cretaceous revived caldera. Through comparing with other similar geologic heritages of global volcanic belts, its scientific value is evaluated. Yandangshan is a typical example of Cretaceous calderas within eastern Asian continent margin, includes all sorts of rhyolitic products, and can be regarded as both a natural museum of rhyolitic rocks and a natural window of tectono-magmatic process in the Asian continent margin. Yandangshan blends the remarkable scientific values, marvelous spectacles and pronounced mountains-and-waters cultures together, which is especially rare all over the world.
