1. Which of the following is NOT a silicate mineral? 1. Quartz (SiO 2 ) 2. Halite (NaCl) 3. Orthoclase (KAlSi 3 O 8 ) 4. Olivine (MgSiO 3 ) Think about other common minerals that are NOT silicate minerals. I could ask you about one of them.

Intrusive or Extrusive? volcanic rocks Intrude into pre-existing rocks Cool slowly underground Extrude out of the earth onto the ground surface All crystals large enough to be seen by the naked eye Some or all crystals too small to be seen by the naked eye aphanitic texture plutonic rocks Cool rapidly above ground Phaneritic texture Finger Signals– I or E

Phaneritic texture means 1. All of the crystals are large enough to be seen by the naked eye 2. None of the crystals are large enough to be seen by the naked eye 3. Some of the crystals are large enough to be seen by the naked eye

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
