無む色しょく鉱こう物ぶつ

noun

felsic mineral; colorless mineral

Geological term for light-colored, felsic minerals such as quartz and feldspar. The English gloss 'colorless mineral' is a literal translation but may be misleading; the term refers to minerals that are typically light in color, not necessarily transparent.

• 花か崗こう岩がんは無む色しょく鉱こう物ぶつを多おおく含ふくむ。

  Granite contains many felsic minerals.

• 無む色しょく鉱こう物ぶつの代だい表ひょう例れいは石せき英えいと長ちょう石せきである。

  Typical examples of felsic minerals are quartz and feldspar.
