摘要
志留系是第一个建立全球年代地层标准的系,含4统、7阶。中国志留系的研究历经百年,以全球志留系划分和对比标准为指导,在不同块体的划分和对比研究中,取得了一系列进展。依据最新成果和已有资料的分析,本文侧重于中国各地区志留纪岩石地层的划分和对比,在综合梳理岩石地层区划、主要剖面地层划分和对比的基础上,将中国志留系重新划分为7个地层区、20个地层分区,从中遴选出70条岩石地层剖面,以组为单元,以生物地层信息为主要根据,以国际标准为统一框架,用对比表的形式,提出中国不同块体间志留纪岩石地层划分和对比的方案。
Silurian is the first system to establish the global chronostratigraphic stratotypes,including four series and seven stages.During the past a hundred years,under the guidance of the international standards,a series of progress has been made in the division and correlation of Silurian in different blocks in China.Based on the latest development and available data,this paper focuses on the division and correlation of the Silurian lithostratigraphy in China.After the carding and emending,the Silurian of China are divided into 7 stratigraphic regions,20 stratigraphic subregions.70 comprehensive lithostratigraphic columns are selected.According to the biostratigraphic data and the formations as the main unit,the lithostratigraphic division and correlation scheme of different Silurian blocks in China is proposed in the form of the correlation table.
