The two most common examples of non-foliated rocks are quartzite and marble. Quartzite is a metamorphic rock from the protolith sandstone. In quartzites, the quartz grains from the original sandstone are enlarged and interlocked by recrystallization. A defining characteristic for distinguishing quartzite from sandstone is that when broken with ...

If the original limestone is pure calcite, then the marble will be white. On the other hand, if it has impurities such as clay, silica, or magnesium, the marble could be "marbled" in appearance (Figure 10.18, bottom).

As noted above, the most famous metamorphic stone is marble. The protolith of marble is limestone, which consists primarily of carbonate minerals such as calcite and dolomite. Meanwhile, silica-rich sandstones will become quartzite. Shale, on the other hand, results in slate after metamorphosis. Well, to a degree, it can also result in …

In general, metamorphic rocks do not react with acid because they are composed of minerals other than calcium carbonate. The notable exception is marble (metamorphosed limestone) which will readily react with acid since it is primarily made of calcium carbonate. Dolomitic Marble will also react with acid if scratched.

Like other metamorphic rocks, marble has no fossils and any layering that appears in it probably does not correspond to the original bedding of the precursor limestone. Like limestone, marble tends to dissolve in acidic fluids. It is quite durable in dry climates, as in the Mediterranean countries where ancient marble structures survive.
