The quartz is more resistant to abrasion and chemically more resistant than the feldspar.  The result is that the quartz remains in the stream but the feldspar breaks down to clay or is dissolved.

What type of mountain forms when a oceanic plate and a continental plate meet

If, however, two continental plates (therefore of similar density) smack into one another, they, instead, lift up against one another.
