摘　　要：根据从江翁浪—陇雷一带金矿沿甲路组中上部铁锰质层之下顺层产出的地质特征,对其成矿规律和成矿作用进行认真的分析和总结,探讨性提出了区内金矿更可能属于"化学障"成矿作用的观点,即从江县翁浪和陇雷等地顺层产出金矿,应是受铁锰质层物理化学屏蔽作用控制的交代蚀变岩型层控矿床类型,系来自深部的含矿热液的S2-与铁锰质层的Fe2+结合生成黄铁矿等硫化物,从而导致金的解析沉淀成矿的结果。For the gold deposits in the Congjiang- Wenglang zones the cautious studies are made for its metallogenetic laws and metallogenesis according to geologic characteristics in occurrence of bedding along upper - middle part of Jialu Formation below ferromanganese beds and the viewpoint is put forward in deliberation that the gold deposits much more likely belong to geochmemical barrier metallogenesis, gold production of bed- ding at Wenglang and Longlei, Congjiang County should be stratabound deposits in type of metasomatically altered rocks dominated by physical chemistry shielding process of ferromanganese beds, which come from deep lying sulphides as pyrite resulted from ore -bearing thermal S^2- and ferromanganese beds Fe^2＋ in conjugation, and consequently lead to gold resolution, deposit and metallogeny
