Correct Answer: 0.5
Solution and Explanation
Fraction of Melt Remaining at Point Q
Step 1: Understanding the Phase Diagram
From the given phase diagram, we observe that point P lies at a composition between A and B. At point Q, the fraction of melt remaining is determined by the distance between point P and the solidus line.
Step 2: Determine the Fraction of Melt Remaining
The fraction of melt remaining at point Q for a magma with initial composition at point P is given as 0.5, according to the phase diagram.
Step 3: Final Answer
The fraction of melt remaining at point Q is: 0.5.
