Igneous rocks [are subdivided] into the following groups: silicic or felsic (or acid, an old and discredited but unfortunately entrenched term), rocks having more than 66 percent silica; intermediate, rocks with 55 to 66 percent silica; and subsilicic, rocks containing less than 55 percent silica.

La notion d'acidité, quelque peu ambiguë pour les roches, a été introduite au milieu du siècle dernier par Élie de Beaumont qui, en fonction de la teneur en SiO₂, distingue les roches acides [plus de 65 %], les roches intermédiaires [entre 52 et 65 %], les roches basiques [entre 45 et 52 %] et les roches ultra-basiques [moins de 45 %].  5, record 3, French, - roche%20basique

The magnesium may be replaced in part by ferrous iron, and the aluminum by ferric iron. Spinel has great hardness, usually forms octahedral crystals(isometric system), varies widely in color(from colorless... to black), and is used as a gemstone. It occurs typically as products of contact metamorphism of impure dolomitic limestones, and less commonly as an accessory mineral of basic igneous rocks; it also occurs in alluvial deposits.  2, record 5, English, - spinel
