摘要
海南省儋州市峨蔓地区是一座天然的地质宝库,地质资源十分丰富,有著名的笔架岭火山口、峨蔓湾、龙门激浪等地质遗迹。笔架岭火山口地质遗迹是北西走向的五个火山口形成的火山口群,火山口附近有巨大的火山集块岩,离火山口2 km的靠海方向有一系列火山碎屑沉积物,构成十分完整的火山口喷发由粗到细的沉积系列。峨蔓湾是儋州第一湾,是中国保存最好的尚未开发的海湾之一,其玄武岩台地及海岸,主要是早更新世和晚更新世火山熔岩构成的,长期以来历经风化和海浪撞击、侵蚀作用形成了陡峭的海蚀崖、海蚀柱等,成为海南岛火山熔岩海蚀地貌发育最典型的岸段。笔架岭火山口及峨蔓湾是国内少有、省内罕见的地质遗迹。利用和保护好该地质遗迹对于海南国际旅游岛建设具有重要的意义。
It has a nature geological treasure trove in Eman area, Danzhou city. Geological heritage of Bijialing Crater is volcanic crater group formed by five NW-trending craters , huge volcanic rock near the crater, a series of volcaniclastic sediments seaward direction two kilometers away from the crater, constitute a very complete caldera eruption sedimentary series from coarse to fine. Mindanao Man Bay is First Beach in Danzhou, best preserved untapped Gulf. A long time after weathering and the waves crash of basalt platform formed sea cliffs and sea column, become the most typical coast of lava sea landscape development in Hainan Island. Use and protection of the rare geological heritage has important implications for the construction of Hainan International Tourism Island.
