摘　　要：本文从元素迁移和同位素交换出发，研究崇浦地区粒状碎斑熔岩和５７０铀矿区熔结状流纹岩的水─岩氧同位素相互作用，并用缓冲开放系统模式估计水─岩氧同位素相互作用的持续时间。Based on the movement of elements and isotpic exchange, it is detailed studied in this paper that water-rock oxygen isotopic interaction of mortar lava in Chongpu area and of welded rhyolite in 570 ore area. Besides,it is estimated that the residence time of water-rocks oxygen isotopic interaction by the buffered open model.
