One of the key concerns in Mongolia’s geomorphological study has been introducing the topic of volcano morphological research, explaining it at a contemporary theoretical level, and then developing it of the knowledge of people. To summarize the results, the composition of garnet lherzolite in Togoo mountain origin basalt was at temperatures between 960-1000°C and pressures between 18-22 kbar. In the south-north direction, the flowing lava is 80 km² in size, 25 km long, and 50 meters thick, with a geochemical composition of 45.1-48.5 percent SiO₂. The Orkhon-Selenge belt’s volcanoes are thought to be late Miocene to Pleistocene in age, and they have a mantle plume source. The morphometric parameters of the Hamilton volcano in Australia and the parameters of the volcanoes under study showed a strong positive correlation (R² = 0.65), which was close to the morphometric parameters of Uranus, Togoo, Tulga, and Jalavch. These volcanoes have a morphology that is similar to that of lava cones. This research can serve as a model for determining the type of craters that are formed due to lava overflows with basic compositions distributed in Mongolia.
