图1 SEDEX型Pb-Zn矿床成因模式对比［7］ （a）近喷口型成因模式；（b）远喷口型成因模式；（a）和（b）成因模式中成矿均受海底喷流沉积作用及封闭、还原沉积环境控制；（c）热液交代成因模式，成矿受压实成岩地层热液交代作用控制，沉积环境为开放、氧化环境

Fig. 1 Genetic model comparison of SEDEX Pb-Zn deposits［7］ （a）Vent-proximal genetic model； （b）Vent-distal genetic model； Both of （a） and （b） are controlled by submarine sedimentary exhalative and enclosed and reduced sedimentary environment； （c）Hydrothermal altered genetic model of SEDEX Pb-Zn deposits. Notably， mineralization is controlled by hydrothermal alteration within the diagenetic strata and formed in the open and oxidation environments
