Itinerary description

国际泥盆-石炭系界线辅助型剖面-桂林南边村界线剖面

灵川南边村剖面国际泥盆-石炭系界线副层型剖面——灵川南边村剖面,是中国第一处获确认的国际地层界线副层型剖面,位于该县定江镇定江行政村南边自然村。该剖面出露完整,为距今三亿六千五百万年前地史时期泥盆纪与石炭纪交界时期的沉积地层,化石十分丰富,包括牙形类、头足类、有孔虫、三叶虫、腕足类、腹足类等共14个门类。其中牙形类生物的演化十分完整,不仅有深水相的管刺动物群,也有浅水相的原颚刺动物群。是目前世界上所发现唯一能够反映先槽形及毛槽形管刺演化谱系的剖面。距今约四亿年至二亿八千五百万年前的地球地层运动,是地球上的生命物质发展的重要时期,而南边村的村民们在修筑水利时无意中发现的岩石上的无数的贝壳等古生物化石,是地球由泥盆纪向石炭纪过渡时期留下的物证。它对于地质考古学家研究这一时期的地球变化和生命起源与发展,具有非常重要的意义。1988年,国际地质科学联合会国际地层委员会确定南边村为国际泥盆—石炭系界线副层型剖面。

该剖面由桂林冶金地质学院于1985年首先发现。
