Here is Leiqiong Global Geopark - Haikou park. In 2004, it was approved as Shishan volcanic cluster national geopark, Haikou. In 2007, it declared global geopark successfully with Zhanjiang Huguangyan national geopark and the North Sea Weizhou island national geopark, which all belong to the Leiqiong rift volcanic belt.

The whole Leiqiong rift volcanic belt have 177 volcanos, including 101 volcanos in Haikou and 76 volcanos in Zhanjiang and Weizhou island, contain all types of basaltic volcanic eruptions. In terms of distribution area and quantity of volcanic rock, they are first in the Quaternary volcanic belt in China. Basaltic volcanic in park is the super probe of rocks in lithosphere within the scope of specific tectonic structure, also is the natural sample to explore the deep magmatism process.

Here distributed large number of pahoehoe lava, scoriaceous lava and massive lava, their formation is relevant to rock flow viscosity, temperature, cooling rate. After the maga eruption, its surface condensed first, then lava under the surface continued to flow, which made the surface rolled. Volcanic bombs can be seen everywhere, they were lava ejectas which were thrown into the air from the crater, and suffered from resistance and tension in the rapid flight, then through rotation and condensation formed.
