摘要
江西省瑞昌市港南金矿是上世纪八十年代发现的小型金矿床,前人称之为"铁帽"型。本文通过对以往勘查资料的进一步分析和野外调查,发现矿体受F1硅化破碎带及溶蚀侵蚀洼地控制,产于破碎带之上的溶蚀侵蚀洼地粘土层中,顶板较平整,底板随基岩侵蚀面的起伏而波动,初步认为属残积红土型金矿,矿区及外围具有进一步找矿的前景。
Located in Ruichang city, Jiangxi province, Gangnan gold deposit is a small-sized gold deposit found in the 1980＇s and has been interpreted as a ＂gossans type＂ deposit by predecessors. The previous exploration data and field surveys show that the ore body, which occurred in the clay layer of corrosional and erosional depression above fractured zone, is mainly controlled by silieified fractured zone of F1 and corrosional and erosional depression. The roof of ore body is flat hut the floor is fluctuated with the erosion surface of bed rock. Therefore, the deposit is regarded as a residual lateritic gold deposit and has a bright prospeetion of exploration in the deposit area and its peripheral areas.
