Effective pulses: Sample is in water when processed with Selfrag. Effective pulses affect the sample; ineffective pulses just cross water body; audible difference. PSS - primary sliding surface; TSS - tertiary sliding surface Organic material was not found in the samples. Table S1. List of micro-breccia samples used for particle size analysis.
