Field samples and microscopic views of the carbonate breccia and isopachous overgrowth that are typical in the lower half of the Algal Dolomite Member of the Dengying Formation at the Gaojiashan section. (A-C) Karst breccia cemented by carbonates in the vugs between breccias. Scale in millimeters. (D-F) Petrographic images of sample 14AD-3, showing isopachous void-filling carbonate cements with concentric textures (brown color) surrounding coarse dolomite sediments (white color). PPL: plane polarized light.
