论盐风化过程及其地貌意义

盐风化是一种重要的地貌过程,本文讨论了盐风化过程的性质、机制和强度及其地貌意义。盐风化包括盐结晶风化作用和盐水化风化作用两种类型。盐风化的强度在很大程度上取决于盐类矿物性质和气候条件。高温和干旱相结合的气候最有利于盐风化过程。通过对未风化岩石和风化岩石的对比,证明盐风化发展的速率很高。Tafoni是盐风化发展阶段的一种重要标志。

A Study on the Salt Weathering Process and Its Geomorphological Significance

Salt weathering is an important geomorphological process. This paper discusses the nature, mechanism, intensity and geomorphologicalsignificance of salt weathering. It includes two types, i. e. salt crystallization and salt hydration. Intensity of salt weathering depends to a large extent on the. nature of salt mineral and climate condition. A climate with high temperature and arid condition is highly favourable for salt weathering. Based on the icontrast between unweathered rocks and weathered rocks, the rate of salt weathfring is very high. Tafoni is an important sign of the deve-lopment stage of salt weathering.
