Tóm tắt

Tại khu vực trung latitudes của Eurasia, các chuỗi loess-paleosol (LPS) cung cấp các hồ sơ trầm tích phổ biến nhất về sự phát triển của môi trường khí hậu trong thời kỳ Đệ Tứ. Tại lưu vực Trung Danube (MDB), các tài liệu này bao gồm ít nhất một triệu năm lịch sử khí hậu, và đôi khi chứa các phát hiện khảo cổ. Chuỗi Zemun LPS được nghiên cứu nằm ở bờ phải của sông Danube tại miền Bắc Serbia. Địa điểm này được công nhận là khu vực bảo vệ, dựa trên các hiện vật thời đồ đá cũ được tìm thấy trên bờ sông và xuất phát từ các mức độ phân lớp chưa rõ nguồn gốc của các vách đá loess dọc theo sông Danube. Nghiên cứu hiện tại nhằm cung cấp bối cảnh phân lớp, môi trường khí hậu cổ và thời gian cho Zemun LPS thông qua các phương pháp từ tính môi trường và phân tích màu. Các cuộc điều tra của chúng tôi đã dẫn đến một sơ đồ tuổi chứ chấp thuận cho phép so sánh trực tiếp với các hồ sơ tham chiếu khác đã được thành lập tốt trong MDB và các nơi khác. Hai lớp tephra tiềm năng được tạm thời phân loại là tephra L2 và Bag, vốn phổ biến cả trong MDB và xa hơn, đã được khảo sát về các thuộc tính từ tính phế liệu của chúng. Mô hình tuổi tích hợp nhận được cho thấy Zemun LPS ghi lại lịch sử chi tiết của việc tích lũy liên tục bụi khoáng từ giai đoạn Isotope Oxy Biển (MIS) 11–5a (c. 430–60 ka). Kết quả của phương pháp tích hợp của chúng tôi cho thấy sự khô hạn liên tục diễn ra trong bốn chu kỳ giữa kỷ băng hà/kỷ băng và chúng tôi thảo luận về những thay đổi tiềm năng trong mùa theo thời gian.
