Volcanic Eruption of Twindaung : Environmental Aspect
- The project area is situated in Sagaing Region. Volcanic craters in this area are aligned in nearly NE-SW. East Twindaung and Taungbyauk craters are phreatomagmatic cones (maars) and the others are cinder cones. During Pliocene, volcanic rocks of the area first erupted and continued up to Holocene. The type of eruption is Vulcanian type phreatomagmatic eruption. The volcanic eruption of the area can be known by studying the volcanic rocks, sedimentary rocks and rock structures in this area. Type, style, and explosivity of the eruption control its products i.e. volcanic rocks and land-forms of the area. From the geological knowledge of the volcanic eruptions of the area combined with chemical and petrological knowledge of their products (in particular, volcanic rocks) it can be known that the effect of the rock and soils on the environments in connection with composition and properties of soils and rocks. The soils on the exposures of air-fall deposits are potassium rich. Therefore, vegetation grows well. Cultivation of millet, paddy rice and other crops is favorable. The soils occurring directly above the Irrawaddian sandstones are so porous and permeable that the trees are difficult to grow, as a result, scarcity of vegetation on them.
