Thec early Cretaceous volcanic rocks in the Yishu rift zone and its adjacent area are mainly basaltic trachyandesite,trachyandesite,and trachyte of alkaline series,as well as some rhyolite,dacite and andesite according to the chemical classification of volcanic rocks(Le Maitre,1989). The rocks of alkaline series are mainly of potassic sub series,in particular,those in easternand western Shandong regions are essentially the potassic sub series whereas some sOdic sub series rocks are present in the Yishu...

Thec early Cretaceous volcanic rocks in the Yishu rift zone and its adjacent area are mainly basaltic trachyandesite,trachyandesite,and trachyte of alkaline series,as well as some rhyolite,dacite and andesite according to the chemical classification of volcanic rocks(Le Maitre,1989). The rocks of alkaline series are mainly of potassic sub series,in particular,those in easternand western Shandong regions are essentially the potassic sub series whereas some sOdic sub series rocks are present in the Yishu rift zone. Their REE distribution patterns show higher LREE conte nt relative to HREE with steep slopesto right and δEu values of 0. 78~1. 28.

沂沭裂谷及邻区下白垩世火山熔岩以碱性系列的玄武粗安岩、粗安岩、粗面岩为主。而亚碱性系列以钙碱性为多。碱性系列以钾质亚系列为主,其中鲁东、鲁西基本上是钾质亚系列,而沂沭裂谷内有一定数量的钠质亚系列。稀土元素标准化曲线均呈向右陡倾斜,其斜率相似,为典型的富轻稀土,而亏损重稀土的型式。多数δEu在0.78-1.28之间。

In order to resolve the regional stratigraphic correlation related to the Middle Permian and Late Permian, the authors studied the palynology of the Upper and Lower Shihezi formations of Permian in coal mines of western Shandong region. More than 100 samples were selected and macerated. Through systematic study, two palynological assemblages in this region have been established as follows:

为解决鲁西地区上、下石盒子组分界问题 ,在相关地层共采集处理孢粉样品 10 0多块 ,经系统研究建立本区上、下石盒子组两个孢粉组合 ,自下而上为 :1)Sinulatisporitessinensis Patellisporitesmeishanensis组合 ;2 )Ant icapipollisreticorpus Macrotorisporagigantea组合。根据所建立的孢粉组合特征 ,经与华北各地二叠系孢粉组合广泛对比 ,进一步阐述各孢粉组合的地质时代 ,并为本区二叠系上、下石盒子组的分界提出了较为可靠的意见。该界线与区内中期华夏植物群晚期和晚期华夏植物群早期植物群界线基本一致。
