A sub-vertically oriented, much faulted, ultramafic sill. The Chromite crystals and grains occur as cumulate layers within the Olivine-rich sill. The Olivine has subsequently been converted to serpentine. Vertical veinlets containing massive Grossular-Hibschite cut the serpentine and Chromite layers at right angles to the layering. The PGE phases have been determined as micron-scale inclusions in the Chromite grains.
