小秦岭地处 NWW 向天山—秦岭—大别山构造带和 NE 向大兴安岭—龙门山构造带交汇部位。区内发育着一系列 NE 和 NWW 向等距平列分布的次级构造带。这两系统的构造互相交织,将该区织编成规律的斜方网格构造格局。构造波峰带控制着成矿带的分布;网结(构造带交汇处)控制着金矿田、矿床和含金石英脉密集区及金的化探异常区的分布;网眼(波谷与波谷带交汇区)是与金有关的Hg、Sb、As 异常分布区,不利金矿形成。具体断裂则控制着具体的含金石英脉和蚀变构造带的分布。这些控矿构造具有级级相套和等间距分布的规律性,因而矿带、矿床、矿脉亦具等间距分布规律。
Small Qinling Mountains are located in NWW to the Tianshan - Qinling - Dabie Mountains tectonic belt and NE to Daxinganling - Longmen Shan tectonic belt intersection. There are a series of sub-tectonic belts with equidistant and equidistant NE and NWW developed in the area. The structures of these two systems are intertwined with each other, and the area is woven into a regular rhombic grid structure. The structure of the peak zone controls the distribution of metallogenic belt; the network junction (tectonic belt interchange) controls the distribution of geochemical anomalies in the gold orefield, ore deposit and gold-bearing quartz vein-intensive area and gold; Area) is the gold-related Hg, Sb, As anomaly distribution, adverse gold formation. Specific faults control the distribution of specific auriferous quartz veins and altered tectonic belts. These ore-controlling structures have the regularity of class-level sets and equidistance distribution. Therefore, the ore-belts, ore deposits and veins also have equal spacing distribution.
