摘　　要：主要依据矿物成分、同位素年龄、侵入岩与断层的错断关系、火山岩内幕岩电旋回性等火成岩形成期次的划分标准,将临邑洼陷古近系火成岩形成期次划分为五期,并对每期特征进行描述。依据该地区古近系火成岩多期次形成的特点,按孔店-沙四期、沙三-沙二期、沙一-东营期三个时期分别阐述了该地区的火成岩分布特征,并详细说明了火成岩形成分布与断裂相辅相成的密切关系。Frequency of igneous rock formation in Linyi sag have been divided into five periods according to reference standards such as mineral composition, isotopic age, leap relation between intrusive rock and faults and the electrical cycling of internal igneous rock. This paper describes its characteristics in each stage and respectively analyses its distribution in Ek-Es4, Es3-Es2, Es1-Ed periods. At the end of this paper, the supplemental correlation between the distribution and formation of igneous rock and faults has been carefully explained.
