| 摘 要： | 通过对新疆北山裂谷已知坡十铜镍矿提取的遥感找矿信息的综合分析与验证,建立了镁铁-超镁铁岩型镍矿的以遥感信息为主的找矿模型.以此找矿模型为指导,我们利用多光谱ETM数据,提取了构造形迹和羟基遥感异常,通过综合分析和实地查证,发现了罗东镁铁-超镁铁岩型镍矿,取得遥感找矿突破.新疆地矿局第六地质队通过矿区地球化学、地球物理测量、地表矿化带的少量工程控制以及一个钻孔的深部控制,圈定出两个镍矿体,求得镍金属预测资源量5.72万吨.罗东镍矿有形成大型矿床的找矿前景,值得进一步投入工作对其进行评价.罗东镍矿的发现进一步扩展了北山成矿带岩浆熔离型铜镍矿的找矿前景.我们还在罗东镍矿的北西部优选了找矿靶区.随着航天技术与信息处理技术的迅猛发展,遥感找矿信息在矿产资源预测与勘查中的作用将会变得越来越重要. |

| Abstract: | By comprehensive analysis and field validation of remote sensing mineral exploration information for the known Poshi Cu-Ni deposit in the Beishan rift zone,Xinjiang,a mineral exploration model mainly of remote sensing information was constructed for mafic-ultramafic type Ni deposits.On the basis of this exploration model,the multi-spectral ETM data were used to extract structural features and hydroxylate remote sensing anomalies,and the LuoDong malic-ultramafic Ni deposit was found through an integrated analysis and on-the-spot checks in July 2005.Thus a breakthrough in mineral exploration using remote sensing has been made.The 6th Geological Party of the Xinjiang Bureau of Geology and Mineral Exploration and Development has outlined two Ni orebodies by geochemical and geophysical surveys of the ultrabasic body,some pits and trenches for the control of the superficial mineralization zone and one borehole for deep control and obtained Ni metal resources of 57,200 tons.The Luodong Ni deposit has potential of a large deposit.It is worthwhile to further input work for evaluation of the deposit.The discovery of the Luodong Ni deposit has further expanded the ore prospects for magmatic liquation-type Cu-Ni deposits in the Beishan metallogenic belt.The authors have selected some ore target areas in the northwest of the Luodong Ni deposit.With the rapid development of the aerospace technology and information processing technology,the role of mineral exploration information using remote sensing in prospecting and forecast of mineral resources will become more and more important. |
