地处胶莱拗陷西北边缘的桃村附近,分布有上侏罗统莱阳组——白垩系王氏组,在上述中生代各地层组中,夹有多层砾岩,而本文所论述的桃村砾岩,系指分布于桃村断裂东南侧的卧龙——铁口之间,在地层层位上不整合于王氏组第二段及其以前地层之上的一套较新的砾岩层。因未获化石,故其确切时代尚难决定,不过从岩石地层学的角度来看,它代表着一次地壳运动之后的产物,有可能归属第三纪。本文暂称之为桃村砾岩。 相似文献

Through the field exploration,we have established the unconformity,distributed eastern of Taocuen fault, between Taocuen conglomerate and Jurassic Laiyang group and Cretaceous Wangshi group,This unconformity is beieved to be the result of a crustal movement which happened at the end of Cretaceous period,May its occurence be in Tertiary period? The analysis of structural location and enviroment of Taocuen conglomerate has shown that it was controlled by the movements of Taocuen fault,which is important to the research of both the evolution of Taocuen fault and Taoeuen basin and the historical evolution of Jiaodong district after Mesozoic era. 相似文献
