Abstract: In order to explore the relationship of magmatite and mineralization（uranium and lead-zinc mine)in Xiangshan uranium polymetallic mining area in Jiangxi province，the microphysiography and petrogeochemistry of the composite pluton are researched，its genetic types and source rocks characteristics are discussed and the ore-forming material sources are analyzed based on the field investigation.The field survey and in-door analysis showed that there are the same lithologic character between the uranium host surrounding rocks and lead-zinc host surrounding rocks.In space，the uranium mine is above the lead-zinc mine.The surrounding rocks belong to rich silicon and high potassium calcalkaline S-type granite with a high degree of difference.Rocks with different lithology are homologous，and mainly come from re-melting of the upper curst metamorphic sandstone.According to rock geochemistry，chronology and regional comparison，it is inferred that，at the stage of tectonic evolution and the formation of the tectonic environment，the surrounding rocks of uranium mine and lead-zinc mine is formed during the tectonic transition environment of the continental extrusion and tension.The mantle provides part of heat sources，but the main heat sources come from the process of the crustal stress releasing and temperature increasing.The sulfur sources of lead-zinc mine mainly come from magmatic hydrothermal of the granitic rocks and are contaminated by the metamorphic rocks series.Sulfur sources of the uranium mine come from the mantle.
