It is suggested that inclusion-rich spar records the former presence of a prolific microbial binder of unknown affinities, which induced precipitation of magnesian calcite that was later either neomorphosed to inclusion-rich calcite (c.
Kimberlite is a host rock to diamonds, but not a source rock: Kimberlite indicator minerals consist of pyrope and eclogitic garnets, magnesian ilmenite, chromite, chorine diopside, forsteritic olivine and diamond and the presence of these minerals is used to determine the proximity of diamond-bearing kimberlites.
