沸石在整个成岩作用范围内生成.其种类主要受原始母质类型及水介质性质控制,在分布上常有垂向分带现象.在盐碱湖现代况积中也有横向分带现象.这主要与原始母质差异及水介质物化性质差异有关.温度基本上不影响沸石的生成与分布.自生沸石温度计不可靠,应停止使用.

Zedites could be generated throughout the process of diagenesis.The types of zeolites are mainly controlled by the varieties of source material and the properties of water medium,and the distributive type of ten shows perpendicularly zonal features.The appearanceof lateral zonality is also present in the modern deposits of saline alkali lakes,since thisclosely relates to the differences of source material and of the physical-chemical properties of water medium.The temperature does not work on the generation and distribution of zeolites,so that the author proposes that authigenic zeolites should not be considered as athermometer and must be stopped using due to its unreliability.
