研究认为，胶东地区晚三叠世(230～200Ma)、晚侏罗世(160～140Ma)、早白垩世中期(130～125Ma)、早白垩世晚期(120～100Ma)花岗质岩石可以与扬子板块、华北板块、太平洋板块相互作用的不同阶段相对应。

Maturity of Lower Cretaceous source rock, researched by the authors, is closely relative to the deposition thickness of the Tertiary and the Quaternary. It shows that source rock at the depth of 4,000-4,400m is low mature, and 4,400-5,200m is in the peak of oil generating. Correspondingly, the source rock of the Zhonggou Formation is immature; the Upper Xiagou Formation is low mature; and the Lower Xiagou Formation and the Upper Chijinpu Formation are in the peak of oil-generating; and the Lower Chijinpu Formation is at the stage of generation of condensate-wet gas with high maturity. There is no source rock reaching the overmature stage of dry gas at present.

可溶有机质转化率、镜质体反射率、热解、生物标志物特征等参数表明：青南凹陷中部的下白垩统烃源岩生油门限深度为4000m（相应的镜质体反射率为0.65％），埋深4000～4400m为低成熟阶段，埋深4400～5200m为成熟生油高峰阶段，因此中沟组烃源岩未成熟，下沟组上部烃源岩低成熟，下沟组下部和赤金堡组上部烃源岩处于成熟生油高峰阶段，赤金堡组下部烃源岩处于高成熟的凝析油—湿气阶段，目前尚无烃源岩达过成熟干气阶段。

结果表明，青山组第一旋回中偏碱性富钾火山岩的形成年龄为10 9.9± 0 。6Ma ，第二旋回酸性流纹质火山岩形成年龄为 10 8.2± 0 。6Ma ，据此确定胶莱盆地青山组火山岩应为早白垩世岩浆活动的产物。

Parisite is hosted in the granular rhyolite, rhyolite and rhyolitic ignimbrite. The host rocks were formed in Late Early Cretaceous Epoch buried to depth of
