| 摘 要： | 砂(页)岩型铜矿床是全球第二重要的铜矿类型,重要性仅次于斑岩型铜矿,具有巨大的资源量和找矿潜力。本文总结了砂(页)岩型铜矿床的时空分布特点,然后选取该类矿床的典型——赞比亚砂(页)岩型铜矿床来探讨大型砂(页)岩型铜矿的控矿因素。本文系统论述了赞比亚砂(页)岩型矿床的地质背景,报道了赞比亚铜带省典型矿床卢安夏矿床黄铜矿Rb-Sr放射性同位素等时线年龄为501±19 Ma,Sm-Nd等时线年龄为499.1±38 Ma,总结了赞比亚砂(页)岩型矿床的分布规律,探讨了其成矿物质来源,认为赞比亚砂(页)岩型矿床为岩浆期后热液充填矿床。

| Abstract: | As the second most important copper deposit type in the world, ranking only second to the porphyry copper deposit, the Sediment-hosted Stratiform Copper Deposit (SSC) has huge resource and is very potential for prospecting. This research summarizes the temporal and spatial distribution characteristics of the SSC Deposits in the world, and selects Zambian SSC deposits as the typical case, in order to explore the possible controlling factors of large-scale SSC deposits. The geological background of the Zambia SSC deposits is systematically described. New Rb-Sr and Sm-Nd isotopic ages of the chalcopyrite in the Luanshya deposit in Zambia Copper Belt Province are reported as 501±19Ma and 499.1±38 Ma, respectively. This paper also summarizes the distribution of the deposits and ore bodies of the SSC deposits in Zambia. The genesis of the SSC Deposits in Zambia is closely related to post-magmatic hydrothermal fluids. |
