| Research Abstract |
The widespread occurrence of petit-spot volcanoes could be indicated by the discovery of petit-spots at other sites. The research cruises were conducted at the area around the Marcus Island and off the Chile Trench oceanward slope in order to explore the submarine petit-spot volcanoes. Radiometric ages of obtained rock-samples are corresponding to the time on plate-flexure. Petit-spot volcanoes, therefore, could be formed ubiquitously wherever the plate flexes under the influence of plate tectonics.
