Geological relics assessment on E’man volcanic coast in the Hainan Island

The E’ man area of Danzhou City, northwestern Hainan Island hosts large volume of volcanic geomorphological relics, especially those geological relics of volcanic coast extensively distributed and best preserved along the coast are of high scientific value. The geological relics are important part of the Leiqiong rift volcanic belt. The unique natural landscapes are part of Leiqiong rifting volcanic zone and formed due to long-term tidal and geological forces in the intertidal zone. The landscapes include volcanic landforms, coastal landforms, water physiognomy, typical geological stratigraphy(strata, rocks)profiles, volcanic edifices and environmental geological relics. On the basis of field investigation and relevant data, this study classified the geological relics of E’man volcanic coast and conducted qualitative evaluation in terms of various values in geological science, popular science, aesthetics and tourism development. Meanwhile, the improved Fishbein-Rosenberg model was used to quantitatively analyze the geological relics. The evaluation and analysis results show that volcanic coastal landforms and geological relics in the E’man area are of distinctive features and the typical landform in China. Therefore, it has had the basis for constructing a provincial geopark, is the best place for geological research and science education, and is of great development value.
