Abstract: Phosphorite is a general term for all phosphate rocks which are economically valuable.It′s a very important mineral raw material in agricultural and industrial fields.It has a high economy value in many fields at home and abroad.Phosphorite is one of the strategic mineral resources in China and distributes extensively in the whole country.The phosphorous deposits in China have been divided into four types during analysing the formation cause and resource characteristics，the most important types of which are magma phosphate deposit，sedimentary phosphorite deposit，and metamorphic phosphate deposit.Screening of object phosphorous-ore geological data by Cores and Samples Center of Land and Resources should consider scales of gold-ore deposits，genetic types，mineralization provinces（belts），and metallogenic epochs，as well as the typical gold deposits with enormous potential.

Key words: phosphorite resources, object geological data, deposit type, mineralization province（belt）
