Abstract: During the diagenetic evolution,the participation of siliceous cement is very important.While the characteristics of the siliceous cement,silica source and the precipitation mechanism are very complicated,which are often controlled by a variety of factors,and it is difficult to analyze the influence of single factor.In this article from the dissolution of feldspar,clay minerals content of diagenetic alteration,and compaction,pressolution,fluid and other sources,the material sources of the siliceous cement have been discussed.Besides the effects of pH value,ionic strength,temperature,pressure and surface characteristics on dissolution precipitation siliceous cements have been also discussed.The results show that the siliceous cement material sources could be controlled by multiple factors,and the differences in different sedimentary diagenetic environment are bigger.Siliceous cement dissolution precipitation is controlled by various factors,in alkaline pH value,the higher the concentration,the higher the temperature,the greater the pressure is more conducive to the dissolution of siliceous cements,vice in favor of the precipitation of the siliceous cements.
