摘要:
碳酸盐白云化作用是白云石(白云岩)成因研究中一个重要领域,对不同碳酸盐白云化作用模式的总结和应用是白云石(白云岩)成因研究的重要内容之一,因而,进一步深入理解目前已有的不同碳酸盐白云化作用模式,将对今后更好地应用和改进现有的模式、甚至总结全新的模式都有重要的现实意义。在大量国内外文献资料分析的基础上,较系统地总结了目前国际上已有的经典碳酸盐白云化作用模式——近地表(浅埋藏)白云化作用模式(萨布哈模式、渗透回流模式、混合水模式)、中—深埋藏白云化作用模式(压实驱动模式、构造挤压模式、地形补给模式、热对流模式)、热液白云化作用模式和微生物白云化作用模式等研究的发展现状和存在问题。
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.
