From: Macro- and microfeatures of Early Cambrian dolomitic microbialites from Tarim Basin, China
Outcrops of the microbialite dolostones of the Interval IV of the Xiaoerblak Formation (Cambrian Series 2) at the Sugaitblak section, Tarim Basin, Xinjiang, China. The Interval IV which overlies the Interval III corresponds to thin sections S-29 to S-39. Interval III is covered by earth. The massive microbial mounds (M1 to M9) are in various sizes with dolomicritic cores and the rocks between the mounds (Int.) are black thin-bedded dolostones
