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

像安提科里岛这样的厚的、岩性重复的层序，往往对试图在区域尺度上对此类单位进行高分辨率对比的地层学家构成挑战。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，但可以将其整合到旋回地层学的现代方法中。拟议研究方案的具体目标是：1)描述安提科里序列中普遍存在的事件层和米级和分米尺度旋回的类型；2)论证它们在区域高分辨率地层对比中的作用；3)以加斯佩盆地为例，检验新开发的盆地外高分辨率对比的安提科西地层格架；更根本的是，4)发展以安提科里序列为代表类型的碳酸盐-硅质碎屑斜坡混合体系的动态沉积模型。除了这些具体目标外，该研究计划的更广泛目标是利用横跨奥陶系-志留系边界的世界上最厚、地层最完整的剖面之一的沉积事件、旋回和层序，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.
