basalt contains silica in the form of silica dioxide (quartz). dust produced from cutting or removing can cause silicosis, a respiratory disease that is typically fatal. cutting must occur under water, and a respirator worn as outlined in section 8. other hazards are due to excessive weight of basalt.
Mar 13, 2013· Best Answer: 1. Rhyolite has the highest percentage of silicon because it is a felsic rock and has more than 65% silica content. Andesite is intermediate and has 5365% silica content while basalt, which is a mafic rock, contains only about 4552% silica.
While working in groups to facilitate peer tutoring, students use samples of four igneous rocks (gabbro, basalt, granite, and rhyolite) to observe differences in texture, color and grain size and make inferences about the relative cooling histories and silica content associated with each magma type.

Rhyolite is a finegrained igneous rock which is rich in silica. 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 rocks.
