11. Pyroxenes rich in both the jadeite and augite endmembers are known as omphacite. 12. Other minerals include anhydrite, augite , and plagioclase. 13. Augite -hypersthene andesite is the dominant rock type.14. In the ground-mass of these rocks, augite is almost universally present. 15. Their black augite and yellow green olivine are also easily observed in hand specimens. 16. Augite and labradorite are found in these dolerites.17. Augite crystals can be found in the hills amongst Lincoln Creek in the hills.18. Clinopyroxene ( augite ) and olivine are common as phenocrysts and in the tholeiitic basalt. 19. Augite exists as euhedral crystals of pale green color, often zonal and readily weathering.20. Their commonest minerals are olivine, anorthite, hornblende, augite , biotite and leucite.
