项目摘要
We propose to test and extend existing sequence stratigraphic and sedimentological interpretations of rocks of Neoproterozoic to earliest Cambrian age in the Adelaide geosyncline, South Australia. Sequence stratigraphy provides an independent method for significantly improving intro-basinal correlation in sparsely fossiliferous rocks, and a physical context in which to analyze biostratigraphic, chemostratigraphic, magnetostratigraphic and geochronological data. To the extent that the waxing and waning of Neoproterozoic ice sheets must have influenced sea level, we infer that at least some of the most persistent sequence boundaries are of global extent. This possibility needs to tested against the emerging stratigraphic record in key sections. The Adelaide geosyncline was selected as a reference section for sequence stratigraphic research on the basis of its great thickness (15 km), quality of outcrop, limited deformation and metamorphism, availability of seismic and core data in adjacent basins of the same age, varied biota (including acritarchs, trace fossils, Ediacara assemblage metazoa, and stromatolites), and amenability to stable isotope geochemistry. There is some potential also for U-Pb geochronology of ash beds, and we propose to search systematically for such layers. The proposed research will be co-ordinated with the work of others under the umbrella of Project 320 of the International Geological Correlation Programme (Neoproterozoic Events and Resources), with the long-term objective of documenting and evaluating the connections between a variety of biological, environmental and tectonic phenomena recorded in younger Neoproterozoic rocks.
我们建议测试和扩展现有的层序地层学 和沉积学解释的新元古代岩石, 南澳阿德莱德地槽的最早寒武纪。 层序地层学提供了一种独立的方法, 显著改善了稀疏区域的流域内相关性 含矿岩石,以及分析的物理背景 生物地层学、化学地层学、磁性地层学和 地质年代学数据 在某种程度上, 我们推断,新元古代冰盖一定影响了海平面 至少有一些最持久的层序边界 全球范围。 这种可能性需要对照 关键地段出现地层记录。 阿德莱德酒店 选择地槽作为层序的参考剖面 根据其厚度大(15 km)的特点, 露头质量好,变形变质作用有限, 邻近盆地的地震和岩心数据的可用性 同一时代,不同的生物群(包括疑源类,遗迹化石, Ediacara组合后生动物,和叠层石),并服从于 稳定同位素地球化学 对U-Pb也有一定的潜力 火山灰层的地质年代学,我们建议系统地寻找 对于这样的层。 拟议的研究将与下列机构协调: 其他人在320项目下的工作 国际地质对比方案(新元古代 事件和资源),长期目标是记录 并评估各种生物之间的联系, 年轻时记录的环境和构造现象 新元古代岩石。
