It had been believed that the genesis of Gejiu tin deposits were granitic mineralization of Yanshanian epoch by most researchers for a long time. However, recently the authors obtain a great deal of information to indicate that the Gejiu tin deposits are occured as mineralization of many time periods and many sources, being divided as three metallogenic series namely the seabed basic volcano- metallogenic series, the seabed exhalative hydrothermal metallogenic series in the Indo-Chinese epoch and the granitic superimposed metallogenic series in the Yanshanian epoch. The metallogenic pattern may be summed up as “rift setting—the volcano-sedimentary metallogenises—the exhalative hydrothermal sedimentary metallogenises—the granit rebuild superimposed metallogenises”.The paper demonstrater the metallogenic viewpoint in terms of the trace rare earth element, stable isotopes and fluid inclusion.
