~ ROCK MINERALOGY - CONCLUSIONS ~

"What we've been discussing, Lou, is whether a rock's mineral composition can tell us if it is igneous, sedimentary and metamorphic!"
"Yes, that's dawned on me!!"
"What conclusions have you reached, Lou?!"
Question 1: In the absence of all other information, can the minerals that a rock contains tell you it must be igneous? If your answer is 'yes', give an example of a mineral whose presence tells you the rock must be igneous.
Question 2: In the absence of all other information, can the minerals that a rock contains tell you it must be sedimentary? If your answer is 'yes', give an example of a mineral whose presence tells you the rock must be sedimentary.
In the absence of all other information, can the minerals that a rock contains tell you it must be metamorphic? If your answer is 'yes', give an example of a mineral whose presence tells you the rock must be metamorphic.
