| 中文摘要: |
| 在智利北部地区的地质找矿工作中，对安托法加斯塔 Henan D矿区开展了岩屑粒度试验和1：10 000岩屑地球化学测量。粒度试验表明，采集B+C层或C层-5~+40目岩屑样品能较好的反映地质特征；岩屑测量圈定了6处Cu-Au-Ag综合异常，通过槽探和钻探异常查证，发现了良好的找矿线索，该区具有找到铁氧铜金型铜矿的潜力。工作表明，在智利安托法加斯塔大区荒漠化景观区实施岩屑测量能够达到明确找矿目标、缩小找矿范围、确定找矿靶区的目的。 |
| 英文摘要: |
| During prospecting in north Chile debris size fraction sampling and geochemical survey at scale 1:10000 were conducted in Henan D mine area. Result of debris size fraction shows that debris samples (-5~+40 mesh) from layer B+C or C can better reflect geological feature of the working area. According result of the debris sampling 6 anomlies (Cu-Au-Ag) were delineated and drilling and trenching at the anomlies show good clews for prospecting potential Fe oxide-Cu-Au type ore deposit. Debris size fraction sampling can clarify goals and reduce prospecting extent and delineate targets fast at Antofagasta desert landscape of northern Chile. |
