MISS in Mesoproterozoic Non-Stromatolitic Limestones: A Case Study from the Third Member of Gaoyuzhuang Formation at Qiangou Section in Beijing

详细信息   
摘要


    

Stromatolitic carbonate succession is common in the Precambrian. In the Yanshan Area, the third member of the Mesoproterozoic Gaoyuzhuang Formation is made up of a particular limestone succession with the sparseness of stromatolites, and this limestone succession has been defined as the non-stromatolitic carbonate succession. For the non-stromatolitic carbonate succession, the third member of the Gaoyuzhuang Formation at the Qiangou section in Beijing is a typical example, in which three third-order sequences can be discerned according to the cyclicity reflected by successions of sedimentary facies.  More importantly, this succession was formed during the stromatolitic golden age, which provides useful information for the further understanding of the evolving carbonate world of the Precambrian.
