| 摘 要： | 南岭钨矿床研究一直是重要的前沿课题,近十余年来测试方法和技术的革新为南岭钨矿床研究注入了新活力,也取得了众多新进展.本文在系统查阅前人研究基础上对其进行总结,概括如下:①该区的岩浆-钨成矿活动不仅有燕山期,也有加里东期和印支期,但以燕山期最为强烈;②花岗岩浆是南岭钨矿床主要的直接物质来源,即使有少部分成矿物质是热液直接对含矿地层淋滤、萃取而来,但却被认为是次要的;③与花岗岩有关钨矿床的成矿流体主要来自花岗岩浆,在成矿作用晚期有不同程度的大气降水混入;④与钨有关的花岗岩主要由下地壳的早—中元古代岩石重熔形成,但地幔岩浆一定程度上参与了花岗岩的形成作用;⑤碱质交代在花岗岩浆演化形成钨矿床的过程中发挥了关键性作用;⑥不同学者对燕山期钨成矿作用动力学背景尚有不同看法,但该时期确定为板内伸展和裂谷环境已达成共识.

Study progress of tungsten deposit in Nanling region |

| Abstract: | The research of tungsten deposits in Nanling region is an important frontier topic.In the past few years,benefiting from application of new testing method and technology,it has achieved great progresses, and are summarized and presented under the predecessor researcher results by this paper as follows:① In Nanling region,Caledonian,Indosinian and Yanshanian granitic and metallogenic cycles have been recog-nized,with the last cycle presenting the most intense period.②Tungsten deposits obtained dominating ore-forming material from granitic magma,but little from strata.③ Their ore-forming fluid was also mainly de-rived from the granitic magma,with different degrees of addition of meteoric water at the late metallogenic period.④ Their related granitic magma primarily come from remelting of Early-Middle Proterozoic crustal, and from mantle materialto some extent.⑤ During the granitic magma evolution,the alkaline metasoma-tism played a key role in leading to the tungsten mineralization.⑥ As for the geodynamic setting of the Yan-shanian granitic and metallogenic cycle,most of scholar have reached an agreement that it formed in intra-plate extension and rift valley environment. |
