Depending on the lava type, they can be rich in silicon, aluminum, magnesium, potassium, iron, sodium, and calcium.
Lava with high viscosity is called slica-rich lava
Thin, easy flowing lava is usually rich in iron and magnesium. Thick, slow moving lava is usually rich in silica.
The lava in the Andes is typically referred to as Andesitic lava, due to its composition being rich in silica and forming characteristic volcanic landforms in the Andean region.
Paricutin volcano in Mexico predominantly erupted mafic lava, which is rich in magnesium and iron and has a low silica content. This type of lava tends to flow more easily compared to felsic lava.
Both rhyolitic and basaltic lava flows have been found in the Yellowstone Caldera. There are alro large deposits of rhyolitic tuff.

Basaltic lava is far less viscous, has less silica, erupts at a higher temperature and is denser than granitic lava (properly called rhyolitic lava when it is on the surface). Basaltic lava is composed primarily of pyroxenes and calcium rich plagioclase with small amounts of olivine. Rhyolitic lava primarily contains alkali feldspars and quartz.

Mafic is a silicate mineral or rock that is rich in magnesium and iron, and is usually dark in color. It is formed from cooling volcanic lava.
When lava and ash cool down it can decompose making soil. Most of the time it is very black because it is so rich and fertile. That is why the people on Hawaii live so close to a volcano, for the rich soil.
Yes, basaltic lava has low silica content compared to other types of lava. Basaltic lava is typically rich in iron, magnesium, and calcium, which contribute to its low silica content. This low silica content also makes basaltic lava less viscous and more likely to flow easily.
Silica-poor lava is called mafic lava. It is low in silica content and high in iron and magnesium, which makes it less viscous and more fluid compared to silica-rich lava. Mafic lava typically erupts at higher temperatures and flows more rapidly, resulting in the formation of basaltic rocks.
