Research on multi-dimension data models and ore area delineation of cobalt-rich crust

The ore area delineation is the aim of cobaltrich crustresearch because it is related to the economic benefit of countries. After analyzing all kinds of data about cobaltrich crust, the models of terrain, abundance, thickness and diggings are established using GIS. Orear eas are delineated using the prescriptive models which are brought forward by the International Seabed Authority, and one of the results is stated. Parameter, which can indicates the result is better or not, is also discussed. The results show that the data models are not perfect because of the limitation of data, and more researches should be done comb-i ning the geophysical data. In the same prospecting condition, the small block model is better than the big block model. The spot areas, where there are nocobal-trich crusts or cobaltrich crusts cannot formore, can influence the placement and amount of oreblocks only when their areas are more than some value.
