Morphology
The noun phrase is directly compositional: 'white' describes the color and 'feldspar' names the mineral, so the meaning 'a feldspar that is white' is immediately derivable from the parts. This adjective+noun composition is cross-linguistically common and follows standard English patterns, so a B1 learner who knows both words will understand it.
Etymology
White feldspar is a simple name that shows its origin: white for its pale color and feldspar from old words for common rock minerals often found in fields. So the name helps you remember it is a common, light-colored mineral that makes up many rocks.
