Question

crystallization points and mineral hardness quiz - m
use the crystallization points graph to answer questions 1-18:

1. crystallization is: magma melting |magma hardening | rock breaking down

2-3) quartz is a _ (high | low) temperature mineral, so as the temperature of a rock heats from low temperature to high temperatures it is the _ (first | last) to melt.

1. imagine a very high-temperature magma chamber (greater than 1,200°c) that is cooling. select one mineral that would be last to begin crystallizing. circle one only.

(quartz | biotite | hornblende | augite | olivine)

1. now imagine a rock that is being heated by the energy inside the earth. as the rock heats up minerals start to melt. select one mineral that would be first to melt. circle one only.

(quartz | biotite | hornblende | augite | olivine)

1. true/false: olivine is both a high temperature mineral and a liquid at 1000°c.
2. true/false: augite would melt by 800°c.
3. true/false: microcline feldspar would be a solid by the time a magma cooled to 850°c.

	mineral	temperature	solid or liquid? (circle one)	crystallization temp (circle one)
9-10	muscovite	at 900°c	solid or liquid	500°c / 700°c / 1000°c
11-12	augite	at 1200 °c	solid or liquid	600°c / 950°c / 1200°c
13-14	anorthite	at 1000 °c	solid or liquid	500°c / 800°c / 1100°c

1. identify two minerals that would be liquid at 650°c. circle two only.

(quartz | muscovite | biotite | augite | anorthite)

1. identify the two minerals that would be crystallizing at the same time at 825°c: circle two only.

(quartz | muscovite | biotite | hornblende | olivine)

1. identify one mineral that would crystallize after microcline feldspar as magma continued to cool: circle one only.

(quartz | muscovite | hornblende | augite | anorthite)

1. identify all minerals that would melt after hornblende as magma heated: circle all.

(quartz | muscovite | augite | olivine | anorthite)

Explanation:

Based on the Bowen's Reaction Series (the standard framework for magma crystallization/melting behavior):

1. Crystall[LLM SSE On Failure]
