| Characteristics and Geological Significance of Quaternary Volcanic Geoheritages in Northern Hainan Island |
| Northern Hainan volcanoes constitute an important segment of Leizhou–Hainan volcanoes, and serve as a significant window to explore the tectonic evolution and basaltic magmatism process since Cenozoic in Southeastern coastal area of China. The volcanoes in the study area are mainly concentrated along the regional NE–trending Changliu–Xiangou Fault. There are abundant and typical types of volcanic geoheritages, especially for their integrated volcanic edifices with high degree of preservation and multiple volcanic eruption. In this paper, based on the geological survey and evaluation of the geoheritages, the authors divided the volcanic geoheritages and related resources into 6 categories, 4 types, 14 subtypes and 39 kinds. Additionally, the authors compared the characteristics and values with features of the typical Cenozoic volcanic geoheritages in China, highlighting their advantages in geoheritages and related resources, and emphasizing the geological significance of Quaternary volcanoes in northern Hainan Island. |
