It also applied to only mafic to intermediate compositions, further distinguishing it from pumice. "Pumice" was acceptable as a rock name, because it presumed a rhyolitic composition, and because rocks of that type are much trickier to pin down in terms of chemical composition, with with a thin section and scope.

3.3 Crystallization of Magma – Physical Geology

3.3 Crystallization of Magma The minerals that make up igneous rocks crystallize at a range of different temperatures. This explains why a cooling magma can have some crystals within it and yet remain predominantly liquid. The sequence in which minerals crystallize from a magma is known as the Bowen reaction series (Figure 3.10 and Who was Bowen).

Porphyry | geological feature | Britannica.com

Rocks have many different textures. Layered sandstone produces a gritty texture, whereas coquina may be rough with cemented shells occasionally producing a sharp edge. Likewise, breccia, which contains pieces of other rocks that have been cemented together, and porphyry, which contains interlocking mineral crystals, tend to be rough.

How to make a thin section - davehirsch.com

What is a thin section? A thin section is a 30 µm (= 0.03 mm) thick slice of rock attached to a glass slide with epoxy. Typical thin section slides are 26 mm x 46 mm, although larger ones can be produced. They are generally covered by another glass slide, a cover slip also attached to the rock with epoxy.
