摘要:

柴胡栏子金矿位于中国东部大兴安岭北北东向构造带与华北地块北缘近东西向构造带的交汇部位。该交汇区经历了多期构造-岩浆活动,产出了柴胡栏子、莲花山、红花沟等多个大-中型金矿床。航磁和遥感资料解译结果表明,矿田内发育北北西向、北西西向、北北东向和北东东向共4个方向的构造形迹,呈现“米字型”结构的展布特点,分别控制了晚古生代岩浆岩(脉岩)和主要金矿床的展布。在柴胡栏子金矿区,4个方向的构造形迹也组成了“米字型”结构,控制了矿体(矿化带)和化探异常的展布。矿田和矿区级别的构造形迹均呈现“米字型”分布特点,是新华夏构造体系分级控岩控矿规律的具体表现。上述认识为矿床成因研究和矿田成矿预测提供了重要的依据。

Abstract:

The Chaihulanzi gold deposit is located at the intersection of NNE-trending tectonic belt in the Great Hinggan Range and the EW-trending tectonic belt in the northern margin of North China Block. The Chaihulanzi, Lianhuashan, and Honghuagou gold deposits in the area have undergone multistage tectono-magmatic activity. Results of aeromagnetic and remote sensing data interpretation show four tectonic trending features (NNW, NWW, NNE and NEE) in the orefield, which constitute the double-cross-shaped structural pattern that controlled the emplacement of Late Paleozoic magmatic rocks (dikes) and gold mineralization. At Chaihulanzi, structural features of these four directions also form a double-cross-shaped pattern, which controlled the distribution of orebodies (mineralized zones) and geochemical anomaly zones. Both the orefield and ore-deposit tectonic features show the double-cross-shaped distribution characteristics, which demonstrate the magmatic and mineralization controled by different levels of the Neo-cathaysian tectonic system. Our findings provide an important foundation for studying metallogenesis and mineral prediction in the orefields.

Key words: Chaihulanzi gold ore field, tectonic system, double-cross-shaped structure, geomechanics, structure control of rocks and ores
