| 摘 要： | 龙脖河铜矿产于中三叠统个旧组灰岩及其下伏地层中下三叠统火山岩建造中。矿床的形成与以红河断裂和阿龙古断裂为界的深海红河裂陷槽海相火山活动及后期的热液蚀变关系密切，矿化受地层、火山活动构造控制。富钠细碧角斑岩、火山碎屑岩、基性侵入岩为该区的主要岩浆岩类型。上述不同岩浆岩均有矿化产出，本文就区内岩浆岩的特征及其与矿化的关系作一简略的探讨。

| Abstract: | The Longbohe Cu deposit is occurred in the Middle Triassic Gejiu Formation and the underlying Middle-Lower Triassic volcanic rock formation.The formation of this ore deposit is closely related to the marine volcanism and the later hydrothermal alteration in the abysmal Honghe rift trough with Honghe Fault and Alonggu Fault as its boundaries.The metallogenesis is controlled by the strata,volcanism and structure.And the main types of magmatic rock are Na-rich spilite-keratophyre,volcaniclastic rock and basic intrusive rock,all of which have metallogenesis.A brief discussion about the characteristics of magmatic rocks and their relationship to the metallogenesis in this ore field is put forward in this paper. |
