郭家屯铅锌矿床位于冀北隆化县郭家屯镇，在空间上与棋盘山深断裂及燕山期陆相火山盆地关系密切。硅酸盐全分析结果显示，同为铅锌矿体围岩的熔结凝灰岩和花岗岩在蚀变过程中有明显的物质交换，其中Si由花岗岩向凝灰岩方向迁移，K、Ca、Mg则由熔结凝灰岩向花岗岩方向迁移。稀土元素分析显示，矿化蚀变过程中稀土元素有从熔结凝灰岩向铅锌矿体和花岗岩方向迁移的趋势，与含氟、含碳和含硫络合剂的活动有关。微量元素分析显示， Cu、Pb、Zn、Ag等矿化元素在蚀变过程中由青磐岩化带向黄铁绢英岩化带迁移。郭家屯铅锌矿的形成与燕山期陆相火山活动及所伴随的热液活动有关，水岩反应与水的电离反应关系密切，并以水岩反应链的形式出现。

The Guojiatun Pb-Zn deposit is located in Longhua County of northern Hebei Province. In space it re-lated closely with Qipanshan deep fault and Yanshanian continental volcanic basin. Silicate analysis shows that obvious material exchange between the welded tuff and the granite in alteration. Si transferred from the granite to the welded tuff, while K, Ca, Mg migrated from the welded tuff to the granite. REE analysis showed that rare earth elements migrated from the welded tuff to the lead-zinc ore and the granite in mineralization, which related with activities of the complexing agents containing fluorine, sulfur and carbon. Trace element analysis shows that mineralization elements such as Cu、Pb、Zn、Ag ect. trended to transfer from propylitization zone to beresitization zone in the alteration. The formation of Guojiatun Pb-Zn deposit associated with the continental volcanic activity in Yanshanian and its hydrothermal activity. Water-rock interaction is closely related to the ionization reaction of water and showed as the form of water-rock interaction chain.
