Quartzite is an example of this rock
WebThe non-foliated appearance of rocks like marble and quartzite are often described as granular or sugary. Protolith rocks composed of just one mineral, for example pure limestone made of nothing but calcite, simply recystallise. In the process of doing so the calcite forms a denser rock consisting of roughly equigranular calcite crystals. WebRocks need not be exceptionally fine grained to have uniform grain size. For example, Figure 10.3 is a photo of a garnet amphibolite from Norway that contains many small visible crystals. The protolith for this rock was, most likely, a basalt. The mineral grains are equal-sized garnet, hornblende, and plagioclase crystals.
