摘　　要：通过对金岭金矿矿区和矿床地质特征的系统分析,在详细研究了金岭金矿埠上矿区控矿断裂面形态、产状的空间变化和矿体空间展布特征的基础上,结合金岭金矿控矿构造面等值线图、工业矿体展布与控矿构造面夹角关系等值线图、勘探线剖面图和应力分析示意图等图件以及成矿后构造的改造与影响,并相互比较,综合研究,揭示金矿体是在断裂构造走向上偏北、倾向上倾角变陡的局部引张部位富集成矿的规律,总结并建立了金矿体受控矿构造左旋正断控制和分段富集的空间定位模型,进而为矿区及其外围开展矿体定位预测和矿产开发提供有益的信息。The shape, occurrence variety of the ore-controlling faults and the orebody stretching characteristics were discussed in detailed based on analysis to the geological characteristics of Jiling gold deposit. And being combined intercomparsion among the contour map of ore-controlling structural plane, the contour map of relationship of included angle between industrial orebody stretching and ore-controlling structural plane, the profile map of prospecting line, the sketch map of stress analysis and reconstruction of postmetallogenic faults, it was concluded that gold ore-bodies were located in partial extensional positions among the ore-controlling fault, where striked northwards and dipped steeply. Then a localization model was proposed, which the orebodies were controlled by laevorotatory normal faults with segmentation enrichment. It will provide usefull information to predict location of orebodies or exploit mineral products in the orefield and its periphery.
