Basalt melts, starts moving up, reaches melting temperature, then releases h20 as it crystallizes into gabbro, which melts into basaltic andesite, which moves up, reaches its melting temp, releases h20, crystallizes into diorite, etc. until andesite/dacite/rhyolite melt and crystallize into tonalite, granodiorite, granite in upper 1/3 of arc crust = GRANITOID

USGS: Volcano Hazards Program Glossary
Volcanic rock (or lava) that characteristically is dark in color (gray to black), contains 45 to 53 percent silica, and is rich in iron and magnesium. Basaltic lavas are more fluid than andesites or dacites, which contain more silica.. Basalt is the most common rock type in the Earth's crust (the outer 10 to 50 km). In fact, most of the ocean floor is made of basalt.

Jun 03, 2019 · Scoria is more often a product of basaltic, lowsilica lavas than of felsic, highsilica lavas. This is because basalt is usually more fluid than felsite, allowing bubbles to grow larger before the rock freezes. Scoria often forms as a frothy crust on lava flows that crumble off as the flow moves. It also is blown out of the crater during ...

How does sand form?
Black sand comes from eroded volcanic material such as lava, basalt rocks, and other darkcolored rocks and minerals, and is typically found on beaches near volcanic activity. Blacksand beaches are common in Hawaii, the Canary Islands, and the Aleutians. The byproducts of living things also play an important part in creating sandy beaches.

Hot Spots | Volcano World | Oregon State University
A hotspot is thermally expanded buoyant mantle (bigger hot mantle that floats), which lifts an overlying plate. As hotspot material rises, the pressure drops so the hotspot begins to melt producing magma. In an oceanic hotspot environment, for example Hawaii, dark, silicapoor basalt magma is produced. The runny basalt forms broad sloping shield volcanoes (Fig. 6).

Volcanic rock
Volcanic rocks are named according to both their chemical composition and texture. Basalt is a very common volcanic rock with low silica content. Rhyolite is a volcanic rock with high silica content. Rhyolite has silica content similar to that of granite while basalt is compositionally equal to volcanic rocks include andesite, dacite, trachyte, and latite.
