Table 2. SNR for LIBS and Acoustic Signal in Calcite and Pyrite Samples^a.

	calcite		pyrite
	Earth	Mars	Earth	Mars
LIBS	525 ± 50	125 ± 40	120 ± 3	11.5 ± 0.5
acoustic	3300 ± 800	35 ± 18	6000 ± 1600	80 ± 20

LIBS SNR values correspond to the Ca II line at 393 nm (calcite) and Fe I line at 388 nm (pyrite). Acoustic SNR values computed from the peak-to-peak amplitude.
