福建福安潘洋地区晚侏罗世火山岩与侵入岩的关系探讨

福安潘洋地区晚侏罗世南囝组碎斑熔岩与潜石英二长斑岩、斑状细粒石英闪长岩及中细粒花岗闪长岩分布于同一火山构造内，形成时间相近，具有相似的岩石学、岩石化学及地球化学特征，均是同源岩浆演化序列不同定位环境下形成的火山-侵入杂岩，构成了喷发相、侵出-溢流相、潜火山相及火山侵入相等4相为一体的共生组合地质体。

On the Relation between Late Jurassic Volcanic Rock and Instrusive Rock in Panyang County of Fuan City, Fujian Province

The late Jurassic Nanyuan formation porphyroclastic lava , secondary quartz monzonite porphyry, fine-grained porphyritic quartz diorite and medium-fine grained granodiorite arc distributed in the same volcanic structure in Panyang County of Fuan City, and form a similar time with similar petrology, petrochemistry and geochemical characteristics. They are the volcanic instrusive complex of the homologous sequence of magmatic evolution under the environment of different positioning, and they have fomed a symbiotic 4 phases combined geological bodiy with eruption phase, invasion-flooding facies, secondary volcanic facies and volcanic instrusion facies.
