[Wien] the difference between Zinc blende and Sphalerite structure

[Gavin Abo]

Sphalerite and zinc blende seems to be due to a language difference.  
Sphalerite is derived from the "Greek" word sphaleros meaning 
treacherous.  Blende is a "German" word meaning blind.  Both names that 
are used interchangeably should be because miners could not "visually" 
distinguish galena (lead sulfide) </wiki/Lead%28II%29_sulfide> from 
sphalerite.
