One of the key elements of rock is the concept of subgenres.Low-MgO rocks are rich in quartz, calcite, or hematite. The same is largely true for Fe2O3(T). High-Fe2O3 meteorwrongs are iron ores, often hematite concretions. The ratio of magnesium to iron does not vary greatly among most kinds of stony meteorites. Rocks with MgO/Fe2O3(T) <0.2 or >6 are probably not meteorites. Simultaneously, rock musicians were beginning to incorporate elements of jazz into their music.
