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。 A series of sedimentary-volcanic rocks under the Late Jurassic Nanyuan Formation volcanic rocks in the Minqingchiyuan-Shanglin area of ​​central Fujian are covered by the Late Jurassic Changling Formation. Through the adjustment of the 1: 50 0 0 area in the area, Lithology combination characteristics, isotopic geological age values, paleontology fossils and contact information and other information, re-defined as Lishan group, Fan pit group, Zhangping group. The discovery of early Jurassic fengkeng formation provides new clues for the study of volcanic basements in central Fujian and prospecting in volcanic areas.
