Molar-tooth structure and sedimentary characteristics of the Wanlong Formation of Neoproterozoic at Erdaojiang section of Tonghua County in southern Jilin Province;
吉林南部通化二道江剖面新元古界万隆组臼齿构造及其沉积特征
Various ribbon-shaped molar-tooth structures are developed in the leionite limestones(aphanitic limestones) of the upper part of the succession of the non-stromatolitic carbonate,and lots of spherical or sub-spherical bodies with the sizes from several millimeters to m.
在该非叠层石序列上部的均一石灰岩(隐晶质泥晶灰岩)中普遍发育大小不等的带状臼齿状构造,与臼齿状构造共同产出的是一些数毫米乃至厘米级的球形体或似球形体。
This paper primarily focuses on the description of Molarochoerus yuanmouensis gen.
