Clay mineralogy, grain size and strontium-neodymium (Sr-Nd) isotopes in core E87-30 of Bay of Bengal

The core E87-30 covers a 15.25 ka sediment record with a time resolution of several hundred years. The data records include clay mineral records, particle size records, and the isotopic data of strontium (Sr) and neodymium (Nd). Clay minerals include illite, smectite, kaolinite, chlorite content, illite chemistry index, and Illilte crystallinity. The sediment grain size record mainly consists of the average grain size.
