Tóm tắt

Đoạn Tailfer (Bỉ, biên giới phía bắc của Synclinorium Dinant) phơi bày các đá vôi nước nông từ Middle Frasnian. Bài báo này đề xuất một phân tích trầm tích dựa trên khoáng vật học cổ điển, dẫn đến việc xác định 19 chuỗi bậc bốn, cấu thành ba chuỗi bậc ba. Phân tích trầm tích này được bổ sung bởi dữ liệu đồng vị carbon và độ nhạy từ tính (MS) (dựa trên mối quan hệ giữa MS và đầu vào lithogenic). Mỗi chuỗi được đặc trưng bởi một sự phát triển riêng biệt của đường cong đồng vị và MS.
