摘要
作者在桂东北发现由生物－热卤水作用形成的新类型铅锌矿床，本文提供了生物成因的硫、碳同位素证据并着重讨论矿床的生物成因。矿床产于寒武－奥陶系与下泥盆统间不整合面之下的构造角砾破碎带，有机碳含量高的地段对矿化有利。
It is found that a new type of Pb Zn ore deposits formed through biological hot brine actions in Northeast Guangxi.It would mainly be discussed its biological genesis in this paper.The deposits located in structural breaking brecciations which overlying by the unconformable contact between the Cambrian Ordovician and the lower Devonian.The localities with high organic content are particularly favorable for the mineralization.Biological textures and organic relics are commonly observed in metallic sulfides and alteration rocks.In addition,the isotopic evidence of S and C are also mentioned in it.
