Kimberlite xenocryst wear in high-energy fluvial systems: experimental studies

Xenocryst minerals from kimberlite have been mixed with gravels of varied grain size and artificially worn in a rotating drum. Results indicate that the minerals are transported with less wear when the finer-grained proportion of the gravel is increased. This is an important consideration when evaluating the natural dispersion of these minerals from their kimberlite host, and can aid in prioritizing stream-sediment anomalies in kimberlite exploration.
