Starting from the definition of the beach bar, this paper comprehensively reviews the latest progress of the beach bar research. According to the deposit types, the locations and the responses to the tidal action, the beach bars can be classified. According to the deposit types, the beach-bars can be divided into the carbonate beach-bars and the detrital beach-bars. According to the development locations, the beach-bars can be divided into the near shore beach-bars and the off shore beach-bars. According to the responses to the tidal actions, the beach-bars can be divided into the low tidal beach-bars, the middle tidal beach-bars and the high tidal beach-bars. In this paper, in view of the sedimentary characteristics of China's lacustrine beach bars, the sedimentary patterns of the beach bars are summarized and their internal microfacies are further divided. The development of the beach bars is controlled by the paleogeomorphology, the hydrodynamic conditions, the material source, the sedimentary cycle, etc. The controlling function of the paleogeomorphology is reflected in the configuration of the shoreline and the local topographic uplifts. The hydrodynamic condition controls the water flow in the development of the beach-bar, which is reflected in the wave actions of different strengths. The material source is the material foundation of the beach-bars and the beach-bars are better developed with abundant materials. The controlling effects of the sedimentary cycle on the beach bar is reflected in two aspects, the rise and fall of the datum level and its cycle. The paleo water depth and the paleoclimate control the development of the beach-bars, especially, the carbonate beach-bars.
