摘要	Titanium, because of its high strength and corrosion resistance, has been widely used in aerospace, medicine, mobile phone and other fields. It is a strategic metallic element in the 20th century. In nature, ilmenite, titanomagnetite and rutile are the most economical titaniferous minerals. Titanium was initially considered to be an inactive metallic element, however, more and more evidences support that it can migrate into metamorphic hydrothermal fluids in certain conditions. The presence of rutile and apatite as paragenetic minerals in high-pressure metamorphic veins may be due to the influence of F-rich fluids on the migration and enrichment of Ti. When fluorapatite precipitates from the F-rich fluids, the K6TiF6 complex will decompose, therefor the solubility of Ti will decrease and rutile will crystallize, which is probably the mechanism of metamorphism and enrichment of the metamorphic rutile deposit. In the magmatic deposits, titanium is often associated with magnetite deposits. It is generally believed that the degree of partial melting, volatile content and the temperature of ore-forming magma determine the formation Ti-bearing deposits or high Ti intrusions. This paper considers that the remelting of recycling rutile-rich oceanic crust or Ti-rich sedimentary deposits is the important source of ore-forming materials for magmatic-type titanium deposits. The formation of sedimentary titanium deposits are related to regional geology, physiography and hydrodynamics. They are often located on the passive continental margin, with high weathering, high-grade titanium sources through weathering, denudation and transgression, and are mainly formed along the costal zone, especially between the low latitudes of 30 degrees N and 30 degrees S. In conclusion, the successful mineralization of Ti is determined by the Ti-rich sources, the depth of provenance, the temperature and degree of partial melting, the degree of contamination of the continental crust, volatile content, the ability of weathering and denudation, etc.
