摘要: 陆地热泉钙华是沉淀于富Ca2+和HCO3-热泉(普遍T≥30℃)的陆地碳酸盐沉积物/岩。热泉钙华独特的形成环境、岩石矿物学特征、地球化学特征和流体性质对古环境、古气候、早期生命起源、新构造运动、陆相热水沉积学、地热资源等方面研究具有重要指示意义。尽管相关学者对陆地热泉钙华开展了相关研究,但由于热泉钙华沉积—成岩过程中受复杂外界条件控制,其时空分布、沉积特征、矿物组成、地球化学特征、微生物作用、流体来源、成岩作用、古气候记录等系列科学问题有待深入研究。在国内外大量文献的基础上,结合研究团队对云南腾冲火山地热区热泉钙华的认识,综述了目前国内外学者对陆地热泉钙华的研究进展,总结了热泉钙华研究意义,提出了当前热泉钙华研究存在的问题及下步研究方向,为更加全面地认识陆地热泉钙华沉积及未来研究提供启示。

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.
