MVT Pb-Zn deposit （Mississippi Valley Type） is one of the most important types of lead-zinc mine. Many large oil and gas fields developed together with MVT type Pb-Zn ore in the foreland basin in the world. Hydrocarbon fluid associated with oil/gas has played a very important role in the mobilization， transportation and precipitation of metal elements of Pb-Zn. Several metallogenic models of MVT Pb-Zn deposit have been established based on the background of foreland basin structure of which hydrocarbon fluid participated in Pb-Zn mineralization， or acted as the role of reductant to precipitate in Pb-Zn minerals. The close connections between the MVT type Pb-Zn deposit and hydrocarbon fluid of oil/gas field in foreland basin is widely recognized by deposit scientists in the world. Currently geologists' attentions have been focused on the role of hydrocarbon fluid in the metallogenic characteristics of MVT Pb-Zn deposit formation， ability of mobilization and transportation of Pb-Zn elements and metallogenic mechanism of hydrocarbon fluid during tectonic evolution history. On the basis of geological and geochemical study of MVT Pb-Zn deposit， ideas and methods of petroleum geology and organic geochemistry should be used to study the coupling relationship of evolution process of hydrocarbon fluid and mineralization process of MVT Pb-Zn deposit.
