桂林不同沉积相泥盆—石炭系界线

桂林地区海相泥盆—石炭系发育,剖面露头连续,具有不同沉积相和不同生物群的泥盆—石炭系界线剖面,可与国内外同类剖面对比.本文对国际泥盆—石炭系界线辅助层型——桂林南边村剖面等作了介绍,依据牙形刺、菊石、有孔虫、介形类、腕足类、珊瑚等多门类化石的地质分布,以及生物事件、岩石（沉积）事件,对泥盆—石炭系界线作了探讨,为不同沉积相和生物群的泥盆—石炭系界线的划分和对比提供了较丰富的资料。

THE DEVONIAN-CARBONIFEROUS BOUNDARY OF DIFFERENT SEDIMENTARY FACIES IN GUILIN

In the Guilin area, marine Devonian-Carboniferous sediments are well developed. The Devonian-Carboniferous boundary section with continuous outcrops and different sedimentary facies and biotas can be well correlated with analogous sections both at home and abroad. This paper introduces the sections including the auxilliary international Devonian-Carboniferous boundary stratotype-the Nanbiancun section of Guilin. The Devonian-Carboniferous boundary is discussed on the basis of the distribution of conodonts, ammonoids, foraminifeis, ostracods, corals and brachiopods as well as biotic events and rock events. The paper provides abundant data for the definition and correlation of the Devonian-Carboniferous boundary with different sedimentary facies and biotas.
