Abstract: On the basis of systematic sampling and analysis of grainsize of loess on Langgangshan Island in East China Sea, features of component were discussed. The Aeoliandust deposition on Langgangshan Island mainly consists of fine particles(10~50 μm),which is similar to the component of loess in other sections of China but comparatively coarser. The average content of clay is 24.9% and coarse particles (>50 μm) on Langgangshan Island section is over 10%, which indicates that the materials of source contain proximal aeoliandust from shelf area of East China Sea in addition to distant aeoliandust from Northwest China.

Key words: grain size, aeolian feature, Langgangshan Island, East China Sea, loess, grain size, aeolian feature, Langgangshan Island, East China Sea
