31. Importantly, large volumes of ultramafic rocks are not found in association with Proterozoic anorthosites. 32. Examples are the ultramafic woodlands and barrens of the endemic species adapted to the soils. 33. Particular floral assemblages associated with highly nickeliferous ultramafic rocks are indicative tools for mineral exploration. 34. Chromite occurs to the base of the Ultramafic Sequence and is mined throughout the dyke. 35. Intrusive komatiites ( ultramafic volcanic rocks ) occur along the Norseman-Wiluna Greenstone Belt. 36. The species is restricted to ultramafic soils. 37. Ultramafic rocks of the Hooggenoeg Formation were most likely not parental for the felsic rocks.38. Ore deposits of this type are restricted to the weathering mantle developed above ultramafic rocks. 39. It occurs in an ultramafic rock deposit. 40. Rocks in the Cobb Valley include gabbro and ultramafic rocks that are now largely serpentised.
