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. WebbIt can sometimes be very difficult to distinguish andesite from closely related rock types like basalt. The best you can do is to first estimate the percentage of dark, mafic minerals in the rock. If it is under 40% and over 10% then your rock is intermediate, which helps you rule out basalt and rhyolite as possibilities. play newburgh

WebbRhyolite. Rhyolite is felsic igneous extrusive rock and it is a fine-grained and dominated by quartz (>20%) and alkali feldspar (>35%).Due to the high silica content, rhyolite lava is very viscous. It is often difficult to identify rhyolites without chemical analysis due to their glassy groundmasses. Many rhyolites consist mainly of glass, and are termed obsidian, … WebbRhyolite is a sticky or viscous lava that usually does not flow very far from the place where it is erupted. In contrast, basalt is a volcanic rock that contains relatively little silica and abundant iron and magnesium, so phenocrysts of olivine and pyroxene are common.

It can sometimes be the predominant igneous rock type in these settings. Rhyolite is more common when the overriding lithosphere is continental rather than oceanic. The thicker continental crust gives the rising magma more opportunity to differentiate and assimilate crustal rock. prime plus bonding agent
