Colorless mineral

The colorless mineral (むしょくこうぶつ, colorless mineral) is a word to name the mineral which does not gain the color in kinds of minerals in a wide sense (is transparent) generally, but often names a thing of colorlessness and the white generally among rock-forming minerals historically. Specifically, I point to a silica mineral (quartz), feldspar, feldspathoid. I am full of Si, Al, Na, K and am called 珪長質鉱物 (フェルシック mineral, felsic mineral) because there are few Fe, Mg.

The igneous rock containing the colorless mineral becomes the whitish color generally. In addition, I do not melt if a high temperature does not have it. Specific gravity is said to be light in comparison with a colored mineral, but there is the exception, too.

I am said to be included a lot in rock-forming minerals constituting the continent earth crust including the granite.
