资源简介：
通过对中国第28次南极科学考察在南极半岛Bransfield海峡采集的D1-7钻孔样品粘土矿物组合、粗颗粒组分、火山灰丰度及AMS14C测年分析，辅以火山灰层对比，建立了该钻孔精确的年代框架，探讨该区域陆源组分含量与古环境古气候变化间的关联。该数据集提供了南极半岛ANT28D1-7孔的年龄数据及陆源组分数据等，为重建该区域中全新世以来的古气候研究提供支持。
Analyses of clay mineral assemblages, coarse-grained components, volcanic ash abundance, and AMS ¹⁴C dating were conducted on core D1-7 samples collected from Bransfield Strait, Antarctic Peninsula during China's 28th Antarctic Scientific Expedition. Supplemented by volcanic ash layer correlation, an accurate chronological framework was established for this core, and the correlation between terrestrial component contents and paleoenvironmental and paleoclimatic changes in this region was explored. This dataset provides age data and terrestrial component data, along with relevant information, for core ANT28D1-7 from the Antarctic Peninsula, and supports paleoclimate reconstruction studies in this region since the Mid-Holocene.
