摘　　要：澳大利亚南部拉克兰造山带西缘(维多利亚州)本迪戈-巴拉腊特褶皱带内分布多处规模不等的金矿体,各矿体展布均与区域构造线方向一致,矿体严格受褶皱及层间断层控制,属造山带的浊积岩型金矿。本文对该区成矿背景、矿床地质特征、成矿规律及找矿标志总结分析的基础上,结合矿集区近年勘查成果的重大发现,提出了进一步的找矿方向,供今后勘查工作部署参考。In the Western margin of the Lachlan orogenic belt(Victoria State)in south Australia,there are many gold ore bodies of different scales distributed in the Bendigo-Balarat fold belt.The distribution of the gold ore bodies is consistent with the direc⁃tion of regional tectonic lines.The ore bodies are strictly controlled by folds and interbedded faults,which belong to turbidite type gold deposits in the orogenic belt.Based on the summary and analysis of metallogenic background,geological characteristics of ore deposits,metallogenic regularities and prospecting criteria in this area,combined with the major discoveries in recent years,this paper puts for⁃ward further prospecting directions for reference for future exploration work.
