中文摘要:
      Q315是近几年来在小秦岭金矿田发现的规模最大且取得勘查突破的南北向近直立的石英脉型金矿床。金矿体受南北走向近直立的构造带控制。Q315号金矿床北段矿体群(Ⅳ、Ⅰ号矿体)、中部矿体群(Ⅱ、Ⅲ号矿体)、南段矿体群(Ⅴ、Ⅵ号矿体)沿构造带走向呈等间距分布,垂向上呈"火炬状"。对原生晕研究表明:由浅至深金矿化具有弱→强→弱的特征,深部南部矿化强于北部,南部Ⅴ、Ⅵ号矿体在500m以深具有较好的成矿潜力。
英文摘要:
      The Q315 gold deposit is a nearly SN upright quartz vein type gold deposit in Xiaoqinling gold ore field, which is the largest gold deposit discovered in recent years. The gold ore bodies are controlled by the north-south-distal tectonic belt. The ore bodies in the northern section (orebodies in IV and I), the central section (orebodies in Ⅱ and Ⅲ) and the southern section (orebodies in V and VI) of the Q315 gold deposit are distributed along the structural belt at even intervals, which vertically present "torch-like" shape. The primary halo study shows that the Au mineralization from shallow to deep is weak→strong→weak. In the depth, the mineralization is stronger in the southern part than that in the north, and the ore bodies of the V and VI have good mineralization potential for in the depth of 500m.
