Re: Bowen's Reaction Series...
You can tell by looking at a typical section of granite which minerals formed first and which later filled in the space in between.
The "rectangular" pink mineral is potassium feldspar. It was first to form, so it has a crystal shape. The tiny gray mineral is quartz. The white and the dark specks are other minerals.
