矿床位于马兰峪复背斜核部即冀东中部侵入岩带西段,钼矿化主要发育在太古宙变质岩、角砾岩及中生代二长花岗岩内,矿脉呈细脉状、浸染状产出,目前初步控制的远景储量有望达到大型以上。通过对该矿床找矿经验、成矿地质特征、物化探异常特征和找矿标志等进行总结,经对比分析发现,区内其它几个中生代花岗岩西侧的钼异常,同样具有较好的找矿前景。该矿床的发现不仅对在冀东马兰峪复背斜核部寻找大型钼矿具有重要的指导意义,而且对促进区域成矿理论与成矿规律的研究,都具有重要的理论与实际意义。
礦床位于馬蘭峪複揹斜覈部即冀東中部侵入巖帶西段,鉬礦化主要髮育在太古宙變質巖、角礫巖及中生代二長花崗巖內,礦脈呈細脈狀、浸染狀產齣,目前初步控製的遠景儲量有望達到大型以上。通過對該礦床找礦經驗、成礦地質特徵、物化探異常特徵和找礦標誌等進行總結,經對比分析髮現,區內其它幾箇中生代花崗巖西側的鉬異常,同樣具有較好的找礦前景。該礦床的髮現不僅對在冀東馬蘭峪複揹斜覈部尋找大型鉬礦具有重要的指導意義,而且對促進區域成礦理論與成礦規律的研究,都具有重要的理論與實際意義。

The deposit is located in the Malanyu anticlinorium, which is the west of the middle of Eastern Hebei intrusive rock belt. The molybdenum mineralization is mainly formed in the Archean metamorphic, breccia and the Mesozoic monzonitic granite, in veinlets, disseminated output. At present, the scale under control is prospective to be more large-scale reserve. Through the research of the prospecting experiences, metallogenic features, the abnormal characteristics of geophysics and geochemistry, indicator for prospecting, we found that there are better exploration prospects of Mo anomalies of the Mesozoic granite in this area. The discovery and research of Taipingcun Mo deposit have great importance guiding significance to find large molybdenum deposit in Malanyu anticlinorium, and to develop regional metallogenic theory and the regularity.
