摘要
Abstract
Geological and economical evaluation methods for on-going Chineseexploration on the cobalt-rich manganese crusts in the Pacific ocean are discussed. The importance of several key indexes including the topography and gradient of seamount, abundance, thickness, coverage and metal grade of crust is emphasized. Survey transect vertical to the bathymetric contour should be integrated with that parallel the water depth contour on the seamount. The resource evaluation method must be correspond with the exploration proceeds. In view of the present objective for the selection of exploration area, the geological method for the resource assessment should be emphasized at the first. Arithmetic average method is suitable for the first and the last stage, and the Kridge method is the best in the middle stage for the evaluation of Co-rich manganese crust.关键词
