Basalt
Miharaite —an alboranite with quartz in the groundmass; a quartz-bearing hypersthene basalt (Miharayama, Japan). Mijakite —a Mn-rich basalt with augite and bytownite phenocrysts in a groundmass, with intersertal texture, composed of feldspar, magnetite, red-brown Mn-pyroxene, and glass (Mijakeshima, Japan).

Quartzite vs Basalt
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various ...

6 Igneous Rocks and Silicate Minerals – Mineralogy
Sometimes extrusive igneous rocks cool so quickly that no crystals form. This is especially likely to happen if lava meets water. The result is a rock composed of volcanic glass called obsidian.Examples of obsidian appeared in Figures 1.21 (Chapter 1) and Figure 4.5 (Chapter 4). In other cases, different minerals may grow to distinctly different sizes.

Basalt A basalt is a fine-grained basic igneous rock containing essential calcic plagioclase feldspar and pyroxene (usually Augite), with or without olivine. Basalts can also contain quartz, hornblende, biotite, hypersthene (an orthopyroxene) and feldspathoids. Basalts are often porphyritic and can contain mantle xenoliths.

Pillow Basalt FAQ
Sometimes the gas bubbles in Franciscan basalt get filled with a bright orange semi-precious form of quartz called carnelian. If basalt is erupted too far under the ocean, the pressure from all the overlying water will not allow the gas bubbles to form. This is the case for most Franciscan basalt, but the basalt at Point Bonita is an exception.

The grain size of the coarse quartz aggregate was 4–8 and 8–16 mm while the grain size of the siliceous sand was less than 4 mm. Basalt-based concrete was designed by substituting 50% of quartz aggregate with basalt aggregates, so the aggregates combination is 50% basalt (22 mm) in addition to 7 and 10% of quartz (4–8 and 8–16 mm), and ...
