The hydrothermal ore deposit formed by volcano activity is one kind of the most important mineral resource reserves in the world. The project, Investigation of Mineral Resource in the Offshore Area of Northeastern Taiwan (1/1), is proposed to evaluate the characteristic of mineral resource offshore northeastern Taiwan. The work in this project is focused on the previous data collection, geochemistry and geophysics analysis of core sediments in offshore area of Kueishantao. The main work items include the technology and equipment of mineral resource investigation, the suggestion of the need of investigation tools, data collection from Ocean Data Bank, National Science Council and Continental Shelf Project, the mechanism analysis of hydrothermal ore deposits, the information of ecology of hydrothermal vent in mid ocean ridge and back arc basin, previous data of seismic, gravity, heat flow, core sediments and ecology, the geochemistry and geophysics analysis of the new sediment cores and the measurement of sea floor temperatures in offshore area of Kueishantao.礦產調查台灣東北海域龜山島mineral resource investigationoffshore northeastern TaiwanKueishantao
