Re: Rocks & Minerals B/C
Okay....
1. What is the blue mineral?
2. What is the green mineral?
3. Why are these two minerals often found together?
Edit: The image isn't working. Hint: Both minerals have a hardness around 3.5-4

Ahhh, sorry for the delay. You're right, though!Magikarpmaster629 wrote:Hmm, 1. Albite plagioclase 2. Felsic igneous rockdechirico wrote:Awesome! Now, next question:
1. ID the mineral. 2. What kind of rocks does this specimen most widely occur in?

Re: Rocks & Minerals B/C
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
