== == Felsic lava has a higher silica content than mafic lava. Felsic lava is slower moving (high viscosity) than the less viscous mafic lava. Mafic lava is higher in dark minerals and higher in the elements iron and magnesium.
A mafic lava flow will move faster than a felsic lava flow due to its lower viscosity. However, felsic magma tends to erupt explosively, producing fast-moving pyroclastic flows instead of lava flows.
Felsic magma.
Lava tubes formed from mafic lava form when the lava forms a crust over itself, creating a tube through which it can flow and later leave empty. Felsic lava forms a crust, but is too viscous to entirely flow out of it.
Oh, dude, Mt. Etna has both mafic and felsic lava. It's like a lava buffet up there! Mafic lava is low in silica and more runny, while felsic lava is high in silica and thicker. So, yeah, Mt. Etna serves up a mix of both, keeping things interesting for all the volcano enthusiasts out there.
Felsic rocks can be either intrusive or extrusive. Intrusive felsic rocks form underground when magma cools and solidifies slowly, creating large crystals. Extrusive felsic rocks form at the Earth's surface when volcanic lava cools quickly, resulting in fine-grained rocks like rhyolite.

Mafic lava is hotter than felsic lava and therefore flows faster.
Felsic lava is a slower moving lava, with high silica content. Most felsic lava deposits as granite, granite, muscovite, and orthoclase.
Felsic magma.
The term felsic des derived from feldspar and silica, which are the primary components of felsic rock.

Felsic lava, due to its high viscosity and generally high gas content tends to produce violent eruptions.
