碱性煌斑岩类的棕闪斜煌斑岩,起源于上地幔。煌斑岩脉空间上与金矿脉关系密切,形成时间
与金成矿作用接近,岩脉的Au、Ag和挥发分的含量较高。煌斑岩浆可能为金矿成矿提供了部

Lamprophyre in the Denggezhuang and Jinqingding Gold Mining Areas of Jiaodong:Its Characteristics and Relationship to Gold Mineralization |
| |
| Abstract: | Petrology, petrological chemistry and trace element characteristics of lamprophyre in the Denggezhuang and Jinqingding mining areas of Jiaodong shows that it belongs to barkevikite-plagioclase lamprophyric series, derived from the upper mantle. Lamprophyric veins, which mainly spread parallel to gold ore veins, might have provided some ore-forming materials and volatiles for gold mineralization. The characteristics of lamprophyre and its intimate connection with gold mineralization suggest that geologic activities related to gold mineralization took place
not only in the crust but also in the upper mantle. |
