Figure 8. (A) Scanning electron microscopy images show the location of energy-dispersive spectrometer (EDS) test spots and the line location of the EDS line composition test on carbonate cements. (B) Plots of Fe/Mn values and Ca content showing the difference of the calcite I, calcite II, and ankerite (Ank) compositions. (C) The result of line composition test reveals the Cal II surrounded by Ank. The line location is labeled in (A). (D) The EDS images reveal the development of Cal I, Cal II, and Ank, and the test spots are labeled in (A). Cal-I = first-phase calcite; Cal-II = second-phase calcite.
