帕里西-维拉海盆的风尘记录数据集（近2 Ma）

本研究对帕里西-维拉海盆PV090102钻孔柱状沉积物进行了系统的粒度、放射性成因Sr、Nd同位素以及风尘通量研究。分别从粒度和同位素角度获得了帕里西-维拉海盆沉积物主要来源于亚洲风尘的关键证据，并基于风尘通量结果重建了近2 Ma亚洲风尘输入帕里西-维拉海盆的历史，探讨了其对近2 Ma亚洲大陆古气候演化的响应。

This study conducted systematic analyses of grain size, radiogenic Sr and Nd isotopes, and aeolian flux on core sediments from Hole PV090102 in the Parisi-Villa Basin. Key evidence that the sediments in the Parisi-Villa Basin are primarily derived from Asian aeolian dust was obtained via grain size and isotopic analyses respectively. Based on the aeolian flux results, we reconstructed the ~2-million-year (Ma) history of Asian aeolian dust input to the Parisi-Villa Basin, and discussed its response to the paleoclimatic evolution of the Asian continent over the past ~2 Ma.
