Mineralogy is an Earth Science focused around the chemistry, crystal structure, and physical (including optical) properties of minerals. Specific studies within mineralogy include the processes of mineral origin and formation, classification of minerals, their geographical distribution, as well as their utilization. petrology is the study of rocks, and the conditions in which they form. An ore deposit is an accumulation of ore. An ore deposit is one occurrence of the particular ore type. We focus on the study fields as follows: accumulation analysis of hydrocarbon near shore; hydrothermal circulation and metal sulphides at the sea floor; rickcobalt encrusted polymetal nodule; origin and distribution rule of placer deposits at coastal and nearshore areas; advanced technology of submarine mineral resources explorations; evaluation methodology of submarine mineral resources. This forms the peculiar marine features in this study field.
