英文摘要	The lacustrine deposits in the middle part of the Hasandong Formation at Yangpori coast, Hadong County, Gyeongsangnam-do, Korea, have been studied in the aspects of paleoenvironments and stratigraphic implications. The examined deposits are gray to dark gray and lacking in red beds. They consist of massive medium-to fine-grained sandstone, planar-laminated fine-grained sandstone, planar- to cross-laminated fine-grained sandstone, interlaminated to interbedded siltstone and mudstone, and shaly mudstone. They arc even-bekided, and wave ripples, stromatolites, gastropod shell-bearing deposits, and invertebrate burrows formed in lake shore to shallow lake are present in these deposits, indicating that they are lacustrine deposits. Tectonically induced cracks were formed in the sublacustrine shaly mudstone beds. The lithostratigraphic unit, 'Yangpori Member' is newly suggested for the gastropod shell deposit-bearing lacustrine beds in the middle part of the Hasandong Formation in Hadong region including study area. The Type area of the Yangpori Member is the costal area of Yangpori, Jingyo-myeon, Hadong County, Gyeongsangnam-do, Korea. The Holostratotype is the sections of the lacustrine deposits of the study area (Component stratotype). The Yangpori Member is the lithostratigraphic unit in which stromatolites firstly appeared in the Gyeongsang Supergroup. It has stratigraphic significance in that arid climatic conditions began to form alkaline lake in the Gyeongsang Basin during the Hasandong time (Aptian-Albian).
