Based on a systematic study of the results obtained from the geophysical and geochemical exploration in the Donggou deposit, the authors generalize in detail the three-dimensional distribution regularity of the ore deposit. The data of geophysical and geochemical exploration were used step by step. The discovery of the superlarge Donggou Mo deposit not only deeply affects the stable development of Mo industry in China in coming decades but also provides rare and valuable experience in search for more molybdenum resources in the Mo mineralized zone of East Qinling-Dabieshan areas. The geophysical and geochemical exploration should be further used as a necessary means.
