Abstract

We analyzed the content of CaCO₃ in the loess of Shengshan Island and Langgangshan Islands,and found the content is only about 0.1%, which is far below that in other loess sections.That should be caused by high precipitation,thin thickness of the section and lots of volcanic eruptions around. The CaCO₃ in the loess of Shengshan Island and Langgangshan Islands belongs to deuterogenic residual CaCO₃, and cannot be used to reflect paleoclimate. We contrast the content of CaCO₃ in the loess of Shengshan Island and Langgangshan Islands with other loess sections, and find the content of CaCO₃ in the loess is decreased equably, which should be the result of different velocity of eluviate and illuviate caused by precipitation changes.
