quartz mineral classifiion

  • Earth Science

    Mineral Classification part 1 Quartz has smooth crystals, but if you were to break a quartz crystal it would not break smoothly because quartz does not have good cleavage. For our purposes we are going to be primarily concerned with whether or not a mineral has excellent, good, or no cleavage.

    In nature, minerals commonly have impurities present in very tiny amounts, usually 3% or less of the crystal by weight. These impurities dont change the primary chemistry. Therefore, the mineral name, or species, doesnt change. They do, however, change some of the mineral s characteristics, so we use a sub classification called a variety.
