Defined as fossil remains of higher plants, rhizoliths are the best fingerpost for studying terrestrial ecosystems changes. Rhizoliths with their related features are also indicators of incidence of palaeosols and subaerialvadose environments in ancient successions. In recent decades, the classification, genesis, geochemistry and significance of rhizoliths have been widely researched at environments such as loess, coastal zone and saline lake, for they can provide important information on paleogeography, paleoclimate, and plant paleoecology. Rhizolith has important significance. In this paper, we summarized the research progresses on rhizoliths at different environments, including their morphology, mineral compositions, carbon and oxygen isotopes, carbon dating and other information in hopes of giving a clear understanding of the formation process of rhizoliths and their significance to environment.
