英文摘要	Sedimentary features and paleoenvironments of the fossil-bearing deposits in the lower part (Jiphyeon site) and the upper part (Jeongchon site) of the Jinju Formation at Jinju area are examined, and their stratigraphic implications are interpreted in relation with the sedimentary and paleontological occurrences of the Jinju Formation. Gastropod shell and plant fossil deposits occur at Jiphyeon site, and they are interpreted to have been formed on a mudflat to shallow lake associated with channels. The occurrence of the Jiphyeon fossil deposits implies that humid climatic condition inducing lake expansion was initiated in the beginning stage of the Jinju Formation after the deposition of the underlying Hasandong Formation to have been formed under arid condition. At Jeongchon site insect fossil deposits are common and estherid and ostracod fossil deposits occur intermittently. It is interpreted that turbidity flows influenced to the formation of these fossil deposits under persistence of lake environment with development of arid condition during the depositon. Considering the paleoenvironments of the fossil deposits at Jiphyeon and Jeongchon sites and overall stratigraphic occurrences of the Jinju Formation, the Jinju Formation is deemed to have been deposited under balanced-fill lake type basin. The lake expansion and subsequent retreat recorded during the development of the Hasadong-Jinju-Chilgok Formations might have been related to the paleoclimatic changes of warming-cooling-warming and the expansion of arid condition in eastern Asia during the early Albian.
