Comparison of actual BFR composition and calculated fault rock compositions of selected trace elements. Trace element anomalies of black fault rocks (BFRs; red diamonds and orange squares and triangles) and calculated fault rock compositions (solid and dashed lines, depending on R values) of selected trace elements (Rb, Sr, Cs, Ba, La, Sm, and Pb) at temperatures of 250°C, 300°C, and 350°C. The vertical axis shows host rock-normalized relative deviation.
