Basalt is a fine-grained volcanic rock that is typically dark in color and rich in iron and magnesium minerals. Quartz, on the other hand, is a mineral composed of silicon and oxygen atoms arranged in a continuous framework of SiO4 silicon–oxygen tetrahedra. Quartz is generally clear or translucent and has a glassy appearance, whereas basalt is typically dark and may contain small crystals of various minerals.
The difference between quartzite and quartz is that quartzite is a metamorphic rock formed from sandstone under heat and pressure, while quartz is a mineral composed of silicon and oxygen. In quartzite, the grains of sandstone have been recrystallized into a interlocking mosaic of quartz crystals, giving it a more durable and non-porous nature compared to quartz.
Quartz and feldspar are two common minerals that form rocks. Quartz is often found in granite while feldspar is found in both granite and basalt.
Both quartz and rock crystal are made up primarily of silicon dioxide. The main difference between them is that rock crystal does not have any significant amount of trace elements that would color it. Quartz does contain coloring trace elements.
Basalt is a dark-colored volcanic rock formed from the rapid cooling of lava, while obsidian is a dark volcanic glass formed from the rapid cooling of lava with high silica content. Basalt has a crystalline structure, while obsidian is amorphous and often exhibits conchoidal fracturing. Basalt is typically denser and more resistant to weathering compared to obsidian.
Ryholite due to the reason that this rock is made up of lighter elements than that of Basalt
Quartzite is metamorphosed quartz sandstone. Basalt is an extrusive igneous rock.
Quartz is silicon dioxide (sand). Diamond is an allotropic form of carbon.
Quartz movement is more traditional. Kintetic quartz relies on different principles and is a bit more accurate.

Cleavage and Fracture
You can tell the difference in density between quartz and galena by measuring their mass and volume. Calculate the density by dividing the mass by the volume. Galena has a higher density than quartz, so the sample with higher density is likely to be galena.

Basalt typically has a smoother texture compared to granite. Where granite is more coarse and grainy due to its composition of minerals like quartz, feldspar, and mica, basalt is fine-grained and its texture is smoother because of its rapid cooling from lava flows.
