摘要:
玲珑金矿田是全球典型的石英脉型金矿产区，矿体空间分布受区域断裂严格控制。石英脉通常以脉群形式出现，在主矿脉的两翼分布多条支矿脉，探索主脉与支矿脉的空间产出关系，对区域地质勘探有重要意义。基于长期野外构造填图与地质研究，提出了玲珑金矿田“入”字型构造的控矿规律。研究表明，主矿脉和支矿脉的空间展布普遍以小角度斜交状产出，形成类似汉字“入”的构造形态。其中，主断裂通常具多期活动性，为导矿通道；次级断裂与主断裂呈锐角相交，多为张扭性或压扭性裂隙，是储矿空间。基于“入”字型构造控矿规律，在西山矿段 108矿脉和大开头矿段 48矿脉下盘等处成功找到了高品位支矿脉，取得了找矿突破。这些找矿成果不仅丰富了玲珑金矿田的构造成矿理论，还为深部及外围找矿提供了重要的科学依据，对同类金矿床在复杂地质条件下的勘探工作具有重要参考价值。

Abstract:
The Linglong Gold Field is a globally representative quartz vein⁃type gold mineralization zone, withorebody distribution strictly controlled by regional fault structures. Quartz veins generally occur in groups, with numerousvein branches distributed on both flanks of the main vein. Investigating the spatial relationship between main vein andvein branches is of great significance for regional geological exploration. Based on long⁃term structural mapping andgeological research, a“入”⁃shaped structural ore⁃controlling pattern is proposed for the Linglong Gold Field. The studyreveals that the main vein and vein branches typically exhibit low⁃angle oblique intersections, forming a geometryresembling the Chinese character“入”. The main fault is usually characterized by multi⁃stage activity and serves as theore⁃guiding channel, while the secondary faults intersect it at acute angles, forming transtensional or transpressionalfractures that provide favorable ore⁃hosting space. Applying this structural model, several high⁃grade vein branchs havebeen discovered in the hanging wall of Vein Branch 108 in the Xishan ore section and Vein Branch 48 in the Dakaitouore section, marking significant breakthroughs in prospecting. These findings not only enrich the structural metallogenictheory of the Linglong Gold Field but also provide a scientific basis for deep and peripheral exploration. The studyoffers valuable reference for the exploration of similar gold deposits under complex geological conditions.
