一、前言我省古生代或印支期之前的地层,主要分布于闽西南及闽中,规模较大的二叠纪海浸,据知只北浸到南平至邵武大埠岗一线。此线之北,只在建瓯房村口、建阳虞墩两地见到零星二叠系文笔山组。在1∶20万南平幅、浦城幅地质图以及1∶50万福建省地质图中、另有两小块“溪口组(?)”,分别出露于南平芹山岩~(*1)和政和城关到铁山一带~(*2)。两处地层时代主要是根据岩性组合及含条带状硅质岩这一特征暂定的,均未有古生物依据,因此代号之后,加了个问号即[T_1x(?)],历来为一疑问。
I. Preface The Paleozoic or Indosinian strata in our province are mainly distributed in the large Permian sea immersion in southwestern Fujian and central Fujian. It is known that only the north is leaking to the front line of Nanbu to Shaowu Dabugang. This line of the north, only in Jian’ou Housing Village mouth, Jian Yang Yu pier saw sporadic Permian Wen Bingshan two groups. In the area of 1: 200,000 Nanpian, Pucheng amplitude map and 1: 500,000 Fujian geological map, there are two other small “Xikou formation (?)”, Respectively exposed in the Chinshan rock ~ (* 1) Hsien and Chengguan to Tieshan area ~ (* 2). The two stratigraphic epochs are tentatively identified based on the lithologic assemblage and the banded chert, without any paleontological evidence, hence the addition of a question mark [T_1x (?)], Which has always been a doubt.
