The climate change of Antarctic Peninsula is particularly sensitive to global warming, thus representing one of the hotspot of the recent climate study. Holocene climate changes in this region provide insights of the future development of the recent rapid warming. Terrigeneous components including clay minerals and coarse fractions in the sediment document direct information of the surrounding environment changes related to climate oscillations and ice-sheet instability. Terrigeneous components are investigated on gravity core Dl-7(62°16.163'S, 56°35.457'W;1100m water depth) collected from the Bransfield Strait, Antarctic Peninsula region, during the 28th Chinese National Antarctic Expedition. The core mainly consists of silty clay, with coarse megascopic black ash layer at 214~222cm. A total of 154 samples were taken at 2-cm intervals over the total core length of 307cm. AMS ~(14)C dating was performed in Beta Analytic Inc., Miami, on organic carbon in 8 bulk samples and benthic foraminifera (Bulimina aculeata) in 1 sample. Other analyses were carried out in State Key Laboratory of Marine Geology, Tongji University. The core covers the period of 0.28 ~ 5.83ka. The organic carbon based ~(14)C age is biased by the fossil carbon contamination of about 2.lka. 7 layers containing abundant tephra were identified (0.33ka, 2.12ka, 2.82?2.94ka, 3.34ka, 3.96ka, 4.76ka and 5.57ka),which can be regionally correlated. Clay mineral composition in the core is rather stable, mainly consists of smectite (>60%), chlorite (24%) and illite (9%), kaolinite is generally less than 6%. Smectite remarkably increases in the major tephra layer (3.96ka). The clay mineral composition suggests the volcanic origin as the major source in this region. The low abundance of deep weathering minerals reflects the weak weathering intensity in the cold Antarctic region. Frequent ice rafted debris (IRD) events are recognized in the Late Holocene interval and consistent with the adjacent marine and ice core records suggesting the cooling and increased glacial ice discharge during the Late Holocene in the Antarctic Peninsula region, driven by the ENSO and seasonal insolation changes.
