| 1. | Geochemical characteristics of precambrian metamorphic rocks in north wuyi region 北武夷地区前寒武系变质岩地球化学特征 |
| 2. | Reservoir capacity of cambrian carbonate of foreslope facies in danzhai and sandu , eastern guizhou 黔东三都-丹寨地区寒武系斜坡相碳酸盐岩的储集性 |
| 3. | The lower palaeozoic group mainly includes cambrian , medial and lower ordovician , which are marine carbonate in the district 下古生界包括寒武系和下、中奥陶统,主要由海相碳酸盐岩构成。 |
| 4. | Notes are also given on the problem related to the regional and local chronostratigraphic subdivisions of china 讨论了与我国寒武系年代地层的划分和建立地方性、区域性年代地层系统的相关问题。 |
| 5. | ( 6 ) the paper founded the cambrian + ordovician + carboniferous - ordovician + carboniferous ( 1 ) petroleum system of the hetian paleo - uplift paleozoic ( 6 )建立了和田古隆起古生界寒武系+奥陶系+石炭系?奥陶系+石炭系( ! )含油气系统。 |
| 6. | According to petrology , biological assemblage and structural features of carbonate rocks , the sedimentary environments of formations of the carbonates in yichang area are reconstructed 根据本区寒武系的岩石学特徵、生物组合特徵和沈积构造特徵重建了各组段的沈积坏境。 |
| 7. | The key point of this thesis is the strontium isotope composition and control factors of cambrian marine carbonate , upper yangtze platform , which the samples were collected from xiushan section in chongqing 论文研究重庆市秀山溶溪寒武系海相碳酸盐的锶同位素组成及主要控制因素。 |
| 8. | This paper also discusses the strontium isotope evolution curve published over the world , present strontium isotope results of the section of cambrian in xiushan of chongqing 本文评述了国际上已有的寒武系海相碳酸盐的锶同位素演化曲线,公布了重庆秀山寒武系海相碳酸盐的锶同位素分析结果。 |
| 9. | The section of the cambrian in xiushan of chongqing has been well re - appraised over again by studying its stratigraphy , sedimentary petrology , sedimentary facies and environment in this thesis 通过较系统地研究重庆秀山溶溪寒武系剖面的地层学、沉积岩石学、沉积相及环境,本文对该剖面进行了重新认识。 |
| 10. | A new global chronostratigraphic subdivision of cambrian system into 4 series and 10 stages has been developed to replace the tripartite traditional framework of the system , which has been used for more that 170 years 摘要重新划分全球寒武系年代地层为4统和10阶,取代了国际地学界沿用了近170年的上、中、下3统的传统划分框架。 |
