摘要
Carbonate eolianites in Houshijing, Putian, Fujian, consist of three sand ridges. The geometry and sedimentary structures of these ridges are described here, and their paleodune types and the paleowind directions are reconstructed on the basis of discussion of genesis. The authors consider that they were vegetated longitudinal dunes or sand drifts and wind shadow dunes or sand shadows which were formed by reworking of adjacent beach sand by prevailing northeast monsoon during the latest Middle Holocene. The wind directions in the past and at present do not appear to have obviously changed.
