| 摘 要： | 钙华是在泉水、河水、湖水、洞穴周围沉积的非海相碳酸钙沉积物。钙华是陆地水循环过程中物质迁移的一种表现形式,研究钙华的形成有助于了解局部水文循环中的物质迁移规律并间接了解古气候与古水文地质条件。部分温泉的泉口附近沉积有形态多样的钙华。本文综述温泉钙华的形成过程、钙华沉积的主要影响因素和它们之间的相互影响关系。水化学条件是钙华沉积的物质基础和必要条件,水动力条件是钙华沉积的充分条件,生物效应对钙华沉积起到加强的作用,沉积环境通过影响水化学条件或水动力条件间接控制钙华的沉积。

| Abstract: | Travertines or tufas are non-marine carbonate precipitates around springs, rivers, lakes and caves, a manifestation of material migration in water cycles on lands. Studying the formation of travertines is helpful to understand the material migration regularity in local hydrologic circulation processes and indirectly examine the conditions of paleo-climate and paleo-hydrogeology. There are various travertines deposits near some of the hot springs. This paper presents a brief review on the formation of travertines from hot springs and the main factors controlling the deposition of travertinesand their interrelation. Research suggests that hydrochemical conditions are the material basis and necessary conditions for travertine deposition, which are the sufficient conditions for travertine deposition. Biological effects may accelerate the travertine deposition and the depositional environment may indirectly control the travertine deposition through changing hydrochemical or hydrodynamic conditions. |
