| 摘 要： | 分布于济南东部六山圈—大有一带的侵入岩，为燕山早期同一岩浆热事件多次侵入形成的杂岩体，依其形成顺序可划分为山张庄、西杜、大有、赵家鹊山四个单元，归并为埠村超单元。该超单元的形成与幔源基性岩浆上侵及同源岩浆分异产生的中偏基性—中性岩浆多次侵入有关，属热气球式膨胀与火山口塌陷复合就位机制。

| Abstract: | Intrusives in Liushanguan-Dayou where located in the east of Jinan is the complex of early Yanshan period,which was formed by multi-time intrusion in the same magmatic-thermal event.According to its forming order,it can be divided into four units,namely Shanzhangzhuang,Xidu,Dayou and Zhaojiaqueshan,which constitutes Bucun superunit.Its formation was related to the intrusion of basic magma(mantle source)to multi-time intrusions of basicly medium to medium magma which differentiated from the same magma.The complex emplacement mechanism was air-ball type inflation and volcanic mouth collapse. |
