Rocks & Minerals B/C

[Magikarpmaster629]

Concept questions!

1. There are two types of metamorphism: regional and contact. Briefly describe the process for each, and give examples of rocks that form in these environments.

2. Although sometimes these are listed as the only types of metamorphism, there are others. Name three other, less prevalent types of metamorphism.

1. Contact metamorphism is caused by rock which comes into contact with magma. The intense heat causes the nearby rock to metamorphose. This is typically over a shorter region because the rock must be in close proximity with the magma. Examples: Marble, Quartzite 

Regional metamorphism typically occurs over a larger area and the metamorphism is usually associated with convergent boundaries or island formation. The intense pressure caused by colliding plates provides an ideal environment for the formation of these rocks. Examples: Gneiss, Mica

2. Retrogressive, dynamic, shock

Awesome! Now, next question:
1. ID the mineral. 2. What kind of rocks does this specimen most widely occur in?

Hmm, 1. Albite plagioclase 2. Felsic igneous rock

Ahhh, sorry for the delay. You're right, though!

Would these types of questions be at national level tournaments? This is my first year !

Let's start this up again for the 2017-18 season!


1. Identify the bigger mineral.
2. Identify the mineral inside of the bigger mineral.
3. What is the name for these two minerals formed together?
4. What is the mineral inside the bigger mineral's main use?

[1. Quartz (crystal), 2. Rutile, 3. Rutilated Quartz, 4. Rutile is used as a titanium ore][/hide]

Obviously I messed up the hide feature again oops

Impressive, Your turn!

Two different examples of the same thing

Questions:
1. What general mineral name would be given to these specimens? (i.e. if it is rose quartz then say quartz)
2. What is the name given to this special formation?
3. How might these specimens have formed?
4. Which property causes these formations? (there are multiple answers to this)
