Zinc blende is one of the commonest of the metallic compounds, and where we find galena or pyrite we are likely to find it also; in one variety it is compact, alter- nating in layers with cleavable galena. It occurs in some regions, as in southwestern Missouri and the adjoining portions of Kansas, in very large deposits. Zincite, Franklinite, and Willemite are all rare minerals, 236 MINERALS, AND HOW TO STUDY THEM. but as they are important ores of zinc at that famous locality, Franklin Furnace..., New Jersey, they will be men- tioned briefly; they are indeed known at only a few other places. ZINCITE, or the red oxide of zinc (ZnO), is often found in bright red grains or masses, sometimes mixed up with the other two minerals named, the black franklinite and the green willemite. It also occurs in larger masses in calcite, and then shows good cleavage. Hexagonal crystals are very rare. The hardness is 4 to 4. 5, and the specific gravity 5. 4 to 5. 7. The deep red or orange color is very characteristic; the streak is orange-yellow.
