摘要
福建中部闽清池园—上莲一带晚侏罗世南园组火山岩地层之下覆盖着一套沉积 -火山岩 ,原划归晚侏罗世长林组 ,通过对该地区 1∶ 50 0 0 0区调 ,依岩性组合特征、同位素地质年龄值、古生物化石及接触关系等资料 ,重新厘定划分为梨山组、藩坑组、漳平组。早侏罗世藩坑组的发现为福建中部火山岩基底地质构造研究、火山岩区找矿提供新的线索。
There is a suit of sedimentary volcanic rocks beneath the strata of Late Jurassic (Nanyuan Formation)volcanic rocks in the Chiyuan Shanglian area of Minqing County,which was grouped into Late Jurassic Changlin Formation.Based on the 1∶50 000 regional geological surveying,isotopic ages and paleaobiofossils,the features of lithologic assemblage and the data of stratigraphic contract relation,in the paper the above mentioned strata are re sorted out and divided into Lishan Formation,Fankeng Formation and Zhangpig Formation.The discovery of Fankeng Formation (Early Jurassic strata)will provide a new clue for studying the geological stuctures of volcanic rock basement and prospecting for ores in a volcanic terrain in the middle part of Fujian Province.
