摘要

滇西保山地区广泛发育奥陶系-志留系仁和桥组黑色岩系。为了建立其笔石地层时空对比框架，以云南保山市施甸县半坡剖面和茶地剖面为研究对象，开展了生物地层学和岩石学研究。研究表明，研究区仁和桥组总厚度约71.6 m，底部发育一层厚约25 cm的古风化壳，与下伏蒲缥组呈平行不整合接触，证明研究区在晚奥陶世曾暴露于地表。基于高分辨率笔石化石调查，识别出了上奥陶统赫南特阶至志留系兰多维列统特列奇阶共9个笔石带，自下而上依次为Metabolograptus persculptus带（仁和桥组第1笔石带，后续简称R1）、Akidograptus ascensus带（R2）、 Parakidograptus acuminatus带（R3）、 Cystograptus vesiculosus带（R4）、 Coronograptus cyphus带（R5）、 Demirastrites triangulatus带（R6）

Lituigraptus convolutus带（R7）

Stimulograptus sedgwickii带（R8）和Spirograptus guerichi带（R9）。与扬子地区龙马溪组笔石生物地层对比表明，保山地区仁和桥组9个笔石带能够与龙马溪组LM1～LM9笔石带相对应。此研究成果为保山地区仁和桥组页岩气调查评价建立了良好的笔石生物地层学基础。

Abstract

The Ordovician to Silurian Renheqiao Formation

characterized by a sequence of well-preserved black shales

is extensively developed in the Baoshan region

southwestern Yunnan Province

China. ObjectiveThe primary goal of this study is to establish a graptolite biostratigraphic framework for the Renheqiao Formation. To achieve this

the research focuses on the Banpo and Chadi sections in Shidian County

Baoshan City

Yunnan Province

which are critical outcrops for biostratigraphic analysis in the area. MethodsA combination of high-resolution biostratigraphic and lithologic records was conducted to precisely define the stratigraphy and identify key biozones within the formation. ResultsThe Renheqiao Formation in the study area is approximately 71.6 meters thick

with a about 25 cm of paleo-weathering crust at the base. It unconformably overlies the Pupiao Formation

indicating that the study area was subaerially exposed during the Late Ordovician. Based on detailed fieldwork and high-resolution surveys

a total of nine graptolite zones were identified

spanning from the upper Hirnantian in the Ordovician to the Silurian Llandovery Telychian stage. These identified graptolite zones are in ascending order as follows: the Metabolograptus persculptus zone (R1)

Akidograptus ascensus zone (R2)

Parakidograptus acuminatus zone (R3)

Cystograptus vesiculosus zone (R4)

Coronograptus cyphus zone (R5)

Demirastrites triangulatus zone (R6)

Lituigraptus convolutus zone (R7)

Stimulograptus sedgwickii zone (R8)

and Spirograptus guerichi zone (R9). ConclusionThe nine graptolite zones of the Renheqiao Formation in the Baoshan region correlate well with those of the Longmaxi Formation (LM1–LM9) in the Yangtze region. This correlation not only strengthens the regional stratigraphic framework but also provides a solid basis for future shale gas exploration and assessment in the Baoshan region.
