Abstract:

Dolomite Problem has been a topic much attention being paid to in sedimentology for a long time. Recently, the recognition that microbes play an important role at low temperatures no matter in modern natural environments or in bacterial culture experiments provides a new perspective and develops a new field. Based on documented data, this article combining the microbial geochemistry conditions in bacterial culture experiments with the natural environmental conditions divides microbial dolomite mechanism into two modes: the anaerobic and the aerobic modes, and the authors detail the microbial dolomite mechanisms including sulfate-reducing bacteria, methanogenic Archaea and halophilic aerobic bacteria. The morphological characteristics of dolomite associated with microbe includ
