证据权重法在黑龙江省伊春地区铅锌矿成矿预测中的应用
|
摘要
伊春地区为黑龙江省重要的铅锌矿集区,矽卡岩型铅锌矿成矿地质条件优越。在成矿条件分析的基础上,借助GIS平台,应用证据权重法优选了地质、物探、化探、遥感等方面的15个证据层,划分了三级远景区,共圈定77处远景区。其中,81.08%的已知矿床(点)位于远景区内,表明本次预测结果较为可靠;54处远景区尚未发现铅锌矿床,其与已知矿床具有相似的成矿条件,有望取得找矿突破,在后续勘查工作中应给予足够的重视。
Yichun area is an important lead-zinc ore district in Heilongjiang Province,where the metallogenic geological conditions of skarn lead-zinc mine are superior.Based on the probe into the metallogenic conditions,15 evidence layers from geological,geophysical,geochemical and remote sensing are optimized and constructed through spatial analysis of the GIS system.Three class metallogenic prospect areas have been divided and seventy-seven prospective areas of lead zinc have been circled finally by the evidence weight model.81.08% of the known deposits(points)are located inthe prospective areas,indicating the reliability of the prediction results.Among them,fifty-four prospective areas have not found lead-zinc deposit and they have the similar metallogenic conditions with known deposits.Thus,big attention should be paid to these areas for a prospecting breakthrough.
