The basic point of a progress report is to summarize the status, progress, and likely future for a particular project.
For example, subequal amounts of quartz and alkali-feldspar, sometimes with biotite and plagioclase, make up granite, a common crustal igneous rock (triangular diagram at the top of the figure). All minerals, like all materials, consist of one or more elements, the building blocks of all matter.
Metamorphic rocks undergo changes in texture, mineralogy, and chemical composition through partial or complete recrystallization of their minerals, either solid-state or solution-mediated [25–27]. These rocks remain essentially solid during metamorphism, but they can flow in a plastic-like manner due to differential pressure.
