2. OrthopyroxeneOrthopyroxene is common inmafic igneous rocks,ingcluding gabbro, basalt andnorite, commonly associatedwith plagioclase andclinopyroxene . It is alsofound in some high grademetamorphic rocks. The term"hypersthene" is often usedas a synonym for

orthopyroxene.

3. AugiteAugite is an important rock-forming mineral in manyigneous rocks, especially ingabbros and basalts, and isalso found in somehydrothermal metamorphicrocks. Augite is a part of animportant solid solutionseries of the pyroxene group.The series includes the

minerals hedenbergite ,CaFeSi2 O6, and diopside, CaMgSi2 O6.

10. SerpentineThe serpentine group describesa group of common rock-forming hydrous magnesium iron phyllosilicate ((Mg,Fe )3Si 2O 5(OH )4) minerals ; theymay contain minor amounts of other elements includingchromium , manganese , cobalt and nickel . In mineralogy andgemology, serpentine may refer to any of 20 varieties belonging

to the serpentine group.

11. MicroclineMicrocline is a polymorph of other minerals that share thesame chemistry but havedifferent crystal structures. If positive identification can notbe made by field methodsthen the specimen may berefered to as a potassiumfeldspar or K-spar. The other k-spar minerals are sanidine ,

orthoclase and anorthoclase.The differences betweenthese minerals are minor inhand samples but microclinetends to be deeper colored,is usually striated oncleavage planes and is theonly one that can be, but isnot always, a deep green(amazonite).

12. SanidineSanidine is the hightemperature form of potassium feldspar (K,Na)(Si,Al) 4O 8. Sanidine mosttypically occurs in felsic volcanic rocks such asobsidian, rhyolite andtrachyte. Sanidine crystallizesin the monoclinic crystalsystem. Orthoclase is a

monoclinic polymorph stableat lower temperatures. At yetlower temperatures,microcline , a triclinic polymorph of potassiumfeldspar, is stable.

13. AnorthoclaseThe mineral anorthoclase((Na,K)AlSi 3O 8) is acrystalline solid solution inthe alkali feldspar series, inwhich the sodium-aluminiumsilicate member exists inlarger proportion. It typicallyconsists of between 10 and36 percent of KAlSi 3O 8 andbetween 64 and 90 percent

of NaAlSi 3O 8.

14. PlagioclaseThe composition of aplagioclase feldspar istypically denoted by itsoverall fraction of anorthite(An) or albite (Ab), andreadily determined bymeasuring the plagioclasecrystal's refractive index incrushed grain mounts , or itsextinction angle in thin

section under a polarizing microscope . The extinctionangle is an opticalcharacteristic and varies withthe albite fraction (Ab). Thereare several namedplagioclase feldspars that fallbetween albite and anorthitein the series. The followingtable shows their compositions in terms of constituent anorthite andalbite percentages.
