摘　　要：水系沉积物测量技术在马达加斯加应用较少,笔者通过在马达加斯加阿巴通德拉扎卡地区水系沉积物测量找矿勘查,探讨该方法在此类地球化学景观地区的应用效果。应用该方法,在马达加斯加阿巴通德拉扎卡地区圈定147处综合异常,通过野外1∶1万地质填图和地表工程揭露,发现钛铁、镍、金等矿产,这说明水系沉积物测量方法适用于马达加斯加中部高原地区的地球化学景观条件,圈定的异常准确、有效,并可取得较好的找矿效果。水系沉积物测量方法可在马达加斯加的同类地区推广使用。Stream sediment survey has been relatively rarely employed in Madagascar.Based on stream sediment ore-prospecting work in Ambatongdelazhaka area of Madagascar,the authors probed into the application effect of this method in such geochemical landscape areas.With the stream sediment survey,147 composite anomaly areas were delineated in Ambatongdelazhaka area,and the delineation proves to be accurate and effective.Titanium-iron,nickel,gold and some other mineral resources were detected through 1∶10 000 field geological mapping and field work,which indicates that the stream sediment survey means is suitable for the geochemical landscape conditions of Central Highlands of Madagascar.The stream sediment survey method can also be extensively used in the same sort of areas in Madagascar.
