| 中文摘要: |
| 笔者对辽河群上百条实测剖面中岩石类型进行了加权平均统计,得出了辽河群中各种岩石类型的百分含量。笔者又在辽河群中已有的上千组岩石化学数据进行了筛选,选取具有代表性的94组数据,用以对辽河群原岩建造恢复和形成构造环境的讨论。认为,辽河群的原岩建造,为巨厚的陆源沉积碎屑岩—内源沉积碳酸盐岩(夹少量火山岩)建造,具有典型的大陆架沉积特征。在威尔逊旋回中,这是成年期洋盆(大西洋)阶段所独具的沉积特征。这个洋盆我们暂且称之为辽吉古元古洋。 |
| 英文摘要: |
| In this paper, the author makes a weighted average of the rock types in the section of the hundreds of the Liaohe Group, and obtains the percentage of various rock types in the Liaohe Group. The author in the Liaohe Group in existing thousands of group of rock geochemical data were screened for select a representative group of 94 of data, to of Liaohe Group original rock building resumes and forming tectonic environment is discussed. Think, Liaohe Group of original rock built for thick terrigenous clastic sedimentary rock - endogenetic sedimentary carbonate (clip a few volcanic rocks) to build, with typical continental shelf sedimentary characteristics. In Wilson cycle, this is the adult ocean basin (the Atlantic) sedimentary characteristics of the unique stage. The ocean we call the Liaoji Paleoproterozoic ocean. |
