摘要/Abstract

摘要：

笏山金矿是胶东栖霞地区新发现的一个大型金矿,金资源量达30余t。矿体产出于新太古代祝家夼组黑云变粒岩和TTG质片麻岩中,受北北东向的西林—陡崖断裂控制。笏山金矿床具有独特的两期金矿化特征,即早期黄铁绢英岩化和晚期石英-黄铁矿-多金属硫化物-重晶石矿化。早期矿化中可见热液独居石与石英黄铁矿脉共生。石英黄铁矿脉中热液独居石SHRIMP U-Pb测年结果为(119.5±3.3) Ma,代表了笏山金矿的成矿早期时间,属于早白垩世,与胶东地区大规模的金矿成矿事件峰值较为一致。黄铁矿微量元素组成结果指示成矿流体主要来源于岩浆流体,原位S同位素结果显示:晚期黄铁矿的δ³⁴S值(平均值为6.75‰)普遍低于早期黄铁矿(平均值为7.26‰),这反映了随着成矿作用的进行,氧化作用加深。早白垩世时期(约120 Ma),胶东地区区域构造体制从挤压向伸展环境转换,引发了大规模的岩浆活动和热液成矿作用,伸展构造为成矿流体的减压和金的沉淀提供了有利条件。石英H-O同位素研究表明成矿后期,成矿流体中混入了大气水,导致流体的δ¹⁸O和δD值降低。结合近年来已有的研究成果认为:古太平洋板块向欧亚板块俯冲,构造体制由挤压向伸展转换,地壳伸展程度控制了金成矿强度。

Abstract:

The Hushan gold deposit is a newly discovered, large gold deposit in the Qixia area of Jiaodong, with gold resources exceeding 30 tons. The ore bodies are hosted in the Neoarchean Zhujiakuang Formation biotite granulite and TTG gneiss, controlled by the NNE-trending Xilin-Douya Fault. The Hushan gold deposit exhibits unique two-stage gold mineralization: an early stage characterized by sericitization and pyritization, and a late stage characterized by quartz-pyrite-polymetallic sulfide-barite mineralization. During the early mineralization stage, hydrothermal monazite is observed coexisting with quartz-pyrite veins. SHRIMP U-Pb dating of this hydrothermal monazite yields an age of (119.5±3.3) Ma, representing the early mineralization age of the deposit. This mineralization age belongs to the Early Cretaceous, consistent with the peak of large-scale gold mineralization events in the Jiaodong Peninsula. The trace element composition of pyrite suggests that the ore-forming fluids were primarily derived from magmatic hydrothermal sources. In situ sulfur isotope analysis reveals that the δ³⁴S values of late-stage pyrite (average 6.75‰) are generally lower than those of early-stage pyrite (average 7.26‰). This suggests an increase in the oxygen fugacity of the ore-forming system during the mineralization process. During the Early Cretaceous (around 120 Ma), the regional tectonic regime in the Jiaodong Peninsula transitioned from compression to extension, which triggered large-scale magmatic activity and associated hydrothermal mineralization. The extensional tectonics provided favorable conditions for the decompression of ore-forming fluids and the precipitation of gold. H-O isotope studies indicate that meteoric water mixed into the ore-forming fluids during the late mineralization stage, leading to a decrease in the δ¹⁸O and δD values of the fluids. Integrated with recent research findings, we conclude that the subduction of the Paleo-Pacific Plate beneath the Eurasian Plate and the consequent transition of the tectonic regime from compression to extension played a critical role in the formation of the Hushan gold deposit.
