| 摘 要： | 在西藏申扎县的格仁错北,在原划于中、上泥盆统查果罗玛组的灰岩地层中,获得了中、晚二叠世的珊瑚化石,经鉴定,共有5属6种及1个未定种:Iranophyllum?sp.,Iranophyllum tunicatum Igo,Neokueichowpora haydeni(Cowper Reed),Praewentzelella irregularis Wu et Zhao,Praewentzelella tibetica(Reed),Waagenophyllum indicum(Waagen et Wentzel),Wentzelella zhongbaensis WuZhao等。根据珊瑚化石的时代及地层岩性特点对研究区以往认为的中、上泥盆统查果罗玛组进行了修订:剖面1—11层修订为中二叠统下拉组,11层之上修订为上二叠统—下三叠统木纠错组。该区木纠错组岩性主要以白云岩、白云质灰岩、灰岩、砂屑灰岩、砾屑灰岩为主,属于蒸发岩台地-开阔台地过渡相沉积。
