前言关于沉积序列中白云石的成因问题有几种假说。许多有关白云石产于更新世到全新世超盐度海洋环境的报告认为,这一环境对白云石化作用是最有利的。富镁超盐度卤水通过渗滤回流向下或向上的迁移作用,是超盐度环境中一般有利于白云石化作用的模式。盐度接近海水的白云石化环境也有报道。 Preface There are several hypotheses about the genesis of dolomite in sedimentary sequences. Many reports of dolomite dating from the Pleistocene to the Holocene over the ocean have suggested that this environment is most beneficial to dolomitization. Magnesium-rich hypersallow brine migrates downward or upward through percolation backflushing and is a mode generally favorable to dolomitization in hypersaline environments. Dolomitization of salinity near seawater has also been reported.
