A seminar by Otago Geology PhD student Rong Zhang.

Monogenetic volcanoes are a type of volcano compared to polygenetic volcanoes, which are characterised by smaller volumes and shorter eruptions. However, they pose no less risk of geological hazard than polygenetic volcanoes.

Investigating the factors that control their formation and predicting their eruptions has become more difficult as more research discovered their complex volcanic origins, plumbing systems and eruption styles. They may have occurred at the same time as polygenetic volcanoes in many areas, such as Changbaishan, China-North Korea and Dunedin, New Zealand, which means that they may be related to polygenetic volcanoes in these areas.

My research used geomorphological, spatial, age, and geochemical information of monogenetic volcanoes to explore the development and evolution of monogenetic volcanic systems and their relationship with polygenetic volcanoes.
