| 龙头山次火山岩体的供金潜力以及该矿床的金成矿模式、控矿作用了解还不够深入,尽管其成因成矿模式受到了较多的关注,但研究实例还不多。燕山晚期是华南地区重要的铜金矿成矿期,广西龙头山斑岩型铜金矿床的成矿时代、温度和压力等都已经得到精确厘定,为研究华南燕山晚期金矿形成与岩浆作用的关系提供理想的研究对象。本文通过系统采集矿石及围岩样品,在详细的岩相学研究的基础上结合前人研究成果得出以下结论:龙头山金矿床具有“上金下铜”分带规律,深部存在斑岩型铜金矿体,这为深部找矿勘查扩大了范围。并首次提出龙头山金矿中铜、金的成矿动力学模式及成矿模式。 |
| 英文摘要: |
| The gold supply potential of the Longshan subvolcanic volcanic rock and the gold mineralization model and ore-controlling function of the deposit are not deep enough. Although the genetic model of the genesis has received more attention, there are not many research examples. The late Yanshanian period is an important copper-gold mineralization period in South China. The ore-forming age, temperature and pressure of the Longshan porphyry copper-gold deposit in Guangxi have been accurately determined which provide the ideal research object to study the formation and magmatism of the late Yanshanian gold deposits in South China. This paper system collects ore and surrounding rock samples. Based on the detailed petrographic research, combined with the previous research results, the following conclusions are drawn:the Longtoushan gold deposit has the zoning law of the up gold and down copper, and the porphyry copper-gold deposit exists in the deep. Copper and gold ore bodies, which expanded the scope of deep prospecting exploration. And for the first time, the ore-forming kinetics model and metallogenic model of copper and gold in Longtoushan Gold Mine were proposed. |
