Textural and microscopic observations of breccia-2. (a) Breccia-2 with chaotic polymict clasts. (b) Various breccia widths and sharp boundaries are the unique features of bx-2. (c) The relationship between clast and matrix in bx-2. (d) Matrix–mineral phase maps and their relative abundances estimated using XmapTools94. (e) SEM-CL of the quartz matrix that depicts the crystallographic orientation of the quartz. (f) Dolomite coating of the quartz clast and (g, h) show the oscillatory zoning with different gray bands in the backscatter detector image. (i) Perfectly double-terminated dolomite crystal. (j) Elemental mapping of dolomite shows distinct characteristics between the core and rim.
