摘　　要：含有铅锌等贱金属矿床的火山沉积盆地内金矿找矿越来越为人们所关注 ,文章通过对麦兹泥盆纪火山沉积盆地含矿建造特征进行分析 ,总结 6种含矿火山沉积岩性建造 ,其岩石的微量元素地球化学表明 ,除盆地两翼边缘的花岗岩外 ,本区岩石均富集Pb、Zn、As、Sb、Au、Ag等元素。根据海相火山沉积盆地演化与成矿分析 ,麦兹地区具有金矿找矿前景。Volcanic sedimentary basins containing lead-zinc ore deposits have been paid more attention for gold prospecting. Based on the analyses of ore-bearing formation in the Maizi Devonian volcanic sedimentary basin,six ore-bearing volcanic sedimentary formations have been proposed. Trace element geochemistry studies of rocks in the formation show that elements of Pb,Zn,As,Sb,Au and Ag are enriched in those rocks with the exception of granites in the two flanks' fringes of the basin. According to evolution of the marine volcanic-sedimentary basis and mineralizing conditions,there is good prospecting for gold in the Maizi area.
