摘　　要：通过成矿元素地球化学、矿石与围岩Pb同位素、S同位素、C同位素、Co和Ni等微量元素、稀土元素的对比研究,认为金矿质主要来源于沉积岩地层,其中中三叠统浊积岩为最重要的矿源岩。Youjiang basin is one of the most important micrograined-disseminated gold districts in China. Studies on geochemistry of ore-forming elements,isotopes of lead,sulphur and carbon, trace elements and rare earth elements show that gold material must have been derived from sedimentary strata, in which Middle Triassic turbidites seem to be the most important source rocks.
