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.
