摘要

 High-resolution grain size, biogenic silica and its mass accumulation rate (MAR) records are gained by AMS¹⁴C dating and analyses of grain size and biogenic silica in Core MZ02 from the muddy area on the inner shelf of the East China Sea. The grain size results reflect a low-energy shallow sea shelf depositional environment dominated by the coastal currents. The biogenic silica content in Core MZ02 is less than 1.5%, mainly controlled by the low supply of biogenic silica remains, high silica dissolution and terrigenous matter dilution.
