Diagenetic characteristics of the microbialites of the Xiaoerblak Formation of the Sugaitblak section, Tarim Basin, Xinjiang, China. a Due to the recrystallization, the size of dolomite in the left is larger than that in the right (separated by the yellow dashed line), in microbial mound of the Interval IV. The reticular fabric remains (se) can be seen. b The recrystallization is stronger than that in a. The reticular fabric (ret) is hard to observe, in the Interval II. c The recrystallization turned the vermicular fabrics into spotted fabrics (sd), in Interval IV. d The residual single lamina (la) caused by recrystallization, in the upper part of Interval I, at the bottom of Interval II. All are photomicrographs of thin sections under plane-polarized light microscope
