Abstract: A thermal spring travertine is a form of terrestrial carbonate rock/deposit formed in Ca2+ and HCO3- enriched hot springs(generally T ≥ 30℃). Its unique depositional environment,petrological and mineralogical characteristics, geochemical features,and fluid characteristics are of great significance to studies of paleoenvironment,paleoclimate,origin of early life,neotectonic evolution,terrestrial hydrothermal sedimentology,geothermal resources,etc. Although geologists have carried out many studies related to thermal spring travertines,their spatial and temporal distribution,sedimentary characteristics,mineral composition,geochemical characteristics,microbial processes,fluid origins,diagenesis,and paleoclimate significance are still unclear because of the complex depositional and diagenetic conditions of thermal spring travertines,and further studies are needed. Based on a detailed literature review and our previous studies, this study:1) reviewed the current research progress of thermal spring travertines, 2) summarized the significance of thermal spring travertine research,and 3) proposed the current problems and next directions in thermal spring travertine research. Combining this information,this study can help us better understand the geological features of thermal spring travertines and their significance and provide new insights into further research.
