一、前言测区属政和县石屯公社富竹庄—马面山一带,福建省区测队(1972年)曾测制过地层剖面(图1),层位划归前震旦系建瓯群的一部分。这次我们对典型地段Ⅰ、Ⅲ(见图1)进行详细的岩性—构造编录,对地段Ⅱ及剖面两侧做了概略地质构造观测,对这里的岩性、变质程度、原岩、地层时代及变质期构造演化序列等问题进行初步研究。本文着重根据测区样品分析中所获微体古生物组合情况结合地质构造特征对地层时代进行探讨。
I. Preface The survey area belongs to the Fu Zhuzhuang-Ma Mianshan area of Shitun Commune, Zhenghe County, and the survey team of Fujian Province (1972) has measured the stratigraphic profile (Figure 1). The strata are classified into the former Sinian Jianou Group Part. This time, we conducted a detailed lithology-tectonic cataloging of the typical sections I and III (see Figure 1) and conducted rough geotectonic observations of the sections II and II. We analyzed the lithology, metamorphism, Age and tectonic evolution sequence of the metamorphic period and other issues for a preliminary study. This paper focuses on the stratigraphic age based on the assemblage of micro-organisms obtained from the analysis of the samples in the area and the geological structure.
