Mar 18, 2015 (A Wilson) - The dike consists of olivine, altered olivine, phlogopite and carbonate minerals (T-249). It contains lesser amounts of spinel, ilmentite, chromite, clinopyroxene, perovskite, apatite, serpentine and some pyrite and quartz (Watson et al., 1978). The rock is medium to fine-grained.
