Abstract：The Tongshankou deposit is a typical skarn-porphyry Cu (Mo) deposit in the East Hubei Province, thick tungsten ore bodies have been discovered in deep part of this deposit recently.In this paper, systematic researches on geological characteristics, petrology, and mineralogy were carried out on tungsten mineralization from the Tongshankou deposit.It is found that tungsten ore bodies were mainly produced at or near the contact zone between sedimentary rocks and granodioritic porphyry.Therefore, their occurrences are controlled by the shape of contact surface.Tungsten can be produced either as a separate tungsten ore body or as a byproduct element in Cu and Mo ore bodies.Scheelite is the mainly tungsten-bearing mineral, and is characterized by a significant enrichment of Mo.Tungsten mineralization process of the Tongshankou deposit is temporally, spatially and genetically associated with skarn alteration, and these features are consistent with those of oxidized W skarns.Tungsten and Cu mineralization are the product of different stages from the same magmatic-hydrothermal process, but the location of W ore bodies are relatively deeper than that of Cu.The Tongshankou porphyry stock shears a lot of similarities with stocks associ-ated with W mineralization in East Hubei Province, suggesting that they were probably partly controlled by Cu and W fertile Jiangnan basement, and the connect part of Jiangnan and Dongling basement under the East Hubei Province probably located nearby the Yangxinpluton.
