Significance of events, cycles and sequences in the sedimentary carbonate record of Anticosti island

像Anticosti岛这样的厚的、岩性上重复的演替，对于试图在区域尺度上对这些单元进行高分辨率对比的地层学家来说，往往是一个挑战。一旦完成了系统的剖面描述或一系列系统的剖面描述，就可以用一套标准工具分析数据，但要与现代旋回地层学方法相结合。提出的研究计划的具体目标是：1)描述Anticosti演替中普遍存在的事件层类型和米级和十米级旋回；2)展示了它们在区域高分辨率地层对比中的应用；3)以加斯佩盆地为例，对新形成的Anticosti地层格架进行盆地外高分辨率对比试验；4)建立以Anticosti演替为代表的碳酸盐-硅-碎屑混合斜坡体系的动态沉积模式。除了这些具体目标之外，该研究项目更广泛的目标是，利用世界上最厚、地层最完整的奥陶系-志留系界线上的沉积事件、旋回和序列，更好地了解全球海平面、气候和海洋变化。

Thick, lithologically repetitive succession like Anticosti Island, often present a challenge to a stratigrapher attempting high resolution correlation of such units at a regional scale. Once a systematic section description or a series of systematic section descriptions has been completed, it is possible to analyze the data with a set of standard tools but integrated into the modern approach of cyclostratigraphy. The specific objectives of the proposed research program are to: 1) describe types of event beds and meter- and decametre-scale cycles prevalent in the Anticosti succession; 2) demonstrate their utility for regional high-resolution stratigraphic correlation; 3) test the newly developed Anticosti stratigraphic framework for high-resolution correlation outside the basin using the Gaspe Basin as an example; and more fundamentally 4) develop dynamic depositional models for mixed carbonate-siliciclastic ramp systems of the type represented by the Anticosti succession. In addition to these specific objectives, the broader aims of the research program are to better understand global sea level, climatic and oceanographic changes using sedimentary events, cycles and sequences present in one of thickest and stratigraphically most complete sections in the world spanning the Ordovician-Silurian Boundary.
