Ans: 1. 3-D framework silicate. H=7; often clear or white;conchoidal fracture.all colors- o. Quartz
2. Family of sheet silicates that display 1 direction of platy cleavege= k. Mica
3.Fe and Mg -rich,dark chain silicates with 2 cleaveges directions prismatic form=n.Pyroxene/hornblende
4.Fe and Mg rich- green silicate,,single silicon -oxygen tetrahydron conchoidal fracture. Abundant in the earth's mantle=l. Olivine
5.Light colored salty mineral found in sedimentary evaporates=h.-Halite
6.Light colored carbonate that efferveces in hydrochloric acid= a.Calcite
7.Metalic and nonmetalic luster. Dark red-brown streak= i.Hematite
8. Metalic luster. Brassy yellow color.Cubic form.often mistaken by gold= m.Pyrite
9. Metalic luster. High density mineral(8). Silver with cubic form and cleavage.Common ore of lead.= d.Galena.
10. Metalic luster.No cleavage.attracted to a mnagnet.=j.Magnetite
11. Greasy luster. Soft.fingernail scratches.Leaves streak on most objects. Found in pencils.=f.Graphite
12.Multi -colored mineral with four cleavage directions and triangular cross-section.Halide= c.Fluorite.
13.Opaque.hardness of 1. metamorphic silicate,soapy feeling= p.Talc
14. Red dodecahedron -shaped silicate(G=7),usually in high grade metamorphic rocks= e.Garnet
15.Three dimensional framework silicate. Twinning of exsolution lamellare. Some pink= b.Feldsper
16. Transparent /translucent sulfate(hardness=2) evaporite.Found in plaster= g.Gypsum
