| 摘 要： | 尖笔岽铅锌矿床位于粤东晚休罗世火山岩盆地中，矿化类型为独特的细脉浸染型脉状矿体，具热液矿床特征。矿石的结构构造研究表明矿液致裂现象明显，成矿溶液在成矿过程中参与了容矿构造的形成，矿化发生于控矿断层形成的雏形阶段。矿床的成因类型为与深部同熔型岩浆来源有关的岩浆期后热液矿床。

| Abstract: | The Jianbidong Pb-Zn deposit located in the Late Jurassic volcanic basin of Eastern Guangzhou. The mineralization made the orebody presented a special veinlet disseminating status, which reflected characteristics of hydrothermal deposit. The structure and texture of the ores shows obviously that ore-forming fluids induced fracture. The ore-forming fluids participated in the formation of ore-host structure during mineralizing period. The mineralization occurred in elementary stage when ore-controlling fault formed. The studying deposit is a postmagmatic hydrothermal deposit related to the sources of syntactic magma in deep part. |
