| 摘 要： | 长江中下游成矿带铜陵矿集区,长期以来为国内外研究的热点地区之一,但大都集中于研究Cu、Au、S、Fe等矿产,而铅锌矿的相关报道或科研工作相对较少。铜陵张家冲铅锌矿位于长江中下游成矿带繁昌盆地内,属次火山口控制的铅锌矿,是繁昌火山岩盆地内发现的第一个有色金属矿床,同时也是通过对盆地内硅化带的系统解剖发现的矿床,有着较高的科研和生产价值。笔者近年来组织了对该区的施工,提交(332+333)铅锌矿石资源量675.87×104t,Pb+Zn金属量11.90×104t。本文旨在通过对该区铅锌矿地质特征、矿床成因、找矿标志及成矿规律等进行总结,进一步丰富该地区成矿模式和理论,为本区乃至整个繁昌盆地下步找矿提供参考和借鉴。

| Abstract: | The Tongling mining camp in the mid-lower Yangtze River metallogenic zone has been one of hot spots for study at home and abroad for a long time, which mostly focused on minerals of Cu, Au, S and Fe, with less report on Pb and Zn. The Zhangjiachong Pb-Zn ore deposit, Tongling is situated in the Fanchang basin of the mid-lower Yangtze River metallogenic zone. Controlled by a subvolcanc crater, it is the first non-ferrous ore deposit ever found in the Fanchang volcanic rock basin, and is also a result of systematic analysis of silicified zone in the basin, bearing higher scientific research and production values. In recent years, the author organized work in the area and presented a resource 332＋333of Pb-Zn ore at 675.87×10^4t, and Pb＋Zn metal at 11.90×10^4t. This paper aimed to summarize geological features, ore genesis, ore-prospecting indicators and ore-forming pattern of Pb-Zn deposits in the area, further enrich metallogenic model and theory for the area and provide a reference for ore prospecting in the area and even the whole Fanchang basin in the future. |
