| 摘 要： | Whole-reck Rb-Sr isochron dating of Sb-bearing granites and alkaline rocks at Gejiu, Yunan Province has been conducted for their emplacement ages and initial ^87Sr/^84Sr ratios. The Sr isotopic compositions of apatites from some basic rocks in Jiasha and granite bodies have also been studied in decal, The genesis and evolution of Gejiu Snbearing granites as well as ore-search indicators are discussed on the basis of the available data in conjunction with the geochemical data on trace elements, such as Rb and Sr, Sr isotopic characteristics of the volcanie rocks, meta-diabase and host rocks, and isotopic features of ore leads.
