| 中文摘要: |
| 团山异常是一个由小比例尺到大比例尺逐次开展化探扫面、缩小找矿范围并最终圈定的一个土壤测量地球化学异常。团山异常位于早白垩世灵山岩体东南部，为一个高温及稀有金属元素组合（Mo-Nb-Ta），以Mo为主，伴有Nb、Ta的异常；Mo异常呈近似等轴状，面积0.258 km2，强度高，规模大，已达到二级浓度梯度，具浓集中心。团山异常地表未见矿化，蚀变仅在局部发育，但验证钻孔中钼矿化发育，钼矿化受区域性NE向剪节理控制，且沿节理面及两侧无蚀变作用，与已知的钼矿床相比，属于细脉型钼矿床。依据异常特征和查证结果显示，团山Mo-Nb-Ta异常具有较大的钼矿找矿潜力。 |
| 英文摘要: |
| Tuanshan anomly is one outlined by narrowing target through coverage of geochemical survey from small scale to large scale. It is a high temperature and rare metal elements(Mo-Nb-Ta combination)anomly located in southeast of the Early Cretaceous Lingshan intrusion. Mo is the main anomly element accompanied by Nb and Ta; Mo anomly takes an approximately equal-axis shape covering an area of 0.258 km2 with high strength about the level 2 concentration gradient and a concentration center. At the anomly no mineralization occurs at surface and alteration is locally developed. Drill holes hit Mo mineralization and the mineralization is controlled by regional NE joints. However, on the surface and either sides of the joint no alteration occurs. Compared with the known molybdenum deposit here is a veinlet type molybdenum deposit. According to the abnormal characteristics and check results, it may be potential for prospecting in the area. |
