Abstract: Dolomitization of carbonates, an important process in nature, has remained as a controversy in sedimentology for years. To thoroughly understand the progress of the study of dolomitization is a necessity to improving existing models and creating new models. Based on the review of references, this paper made a summarization of the current dolomitization models, such as near-surface (shallow buried) dolomitization models (Sabkha model, seepage reflux model, mixing zone or Dorag model), the intermediate-deeply buried dolomitization models (compaction model, tectonic (squeegee) model, topography driven model, thermal convection model), hydrothermal model and microbial model, with emphasis on the present status and problems of each model.
