摘要柴達木盆地西部第三系的碳酸鹽巖層中發現有藻類、介形蟲、有孔蟲、腹足類、多毛類等化石。The results improve our understanding of the utility of tl as an indicator of sedimentary environment and provide insight into what types of ocean sediments are amenable for study. the comparison of the 18o with the tl cycles indicates that the tl dose display the expected coupling relation with interglacial and glacial climate cycles
尤以位於東經90海嶺上的以遠洋沉積作用為主的md81349巖芯最為理想,陸源剝蝕產物在其沉積記錄中所佔比例較少,有孔蟲和超微化石為代表的遠洋成因的灰白色生物軟泥構成主要的沉積組分。Based on the elaborate research on the stable oxygen isotope stratigraphy, carbonate stratigraphy, biostratigraphy, magnetic susceptibility, grain size and clay mineral of cores marked md81349, md77190, md77181 and bar9427 in the northeastern indian ocean, this thesis focus on the application of the tl properties in the above cores to infer the paleoclimatic change, and discuss the response of tl of sedimentary records with climatic cycles during the last 300, 000 years
論文對東北印度洋地區不同地理位置的md81349 、 md77190 、 md77181 、 bar9427四支巖芯的全巖熱釋光和md81349巖芯純凈有孔蟲的熱釋光測量,與已知氧同位素地層資料對比后發現四支巖芯的熱釋光變化與氧同位素地層揭示的氣候變化及可能的隆升事件有良好的對應關系。
