Viscose lava e.g. andesitic or rhyolitic. This might not be the definition your looking for though.

The type of magma which is thick and slow is Felsic Magma.
The magma in a cider cone is usually fairly thin.
magma pushed into a thick sill can form what
Felsic magma tends to be thick and viscous, while mafic magma tends to be fluid.
Gaseous thick magma equals massive explosion.
The type of magma which is thick and slow is Felsic Magma.
An acid magma or a granitic magma.
The magma in a cider cone is usually fairly thin.
magma pushed into a thick sill can form what
The three things that determine how thick or thin magma is temperature, silica content, and gas content.
Felsic magma tends to be thick and viscous, while mafic magma tends to be fluid.
Silica-rich magma is much more thick and viscous.
Gaseous thick magma equals massive explosion.
Silica is sand dust.
magma
Silica in natural form can be both particles or thick on fusion as in felsic magma origin
It depends on the texture of the magma, if it is thick then it won't let the gases escape, and if it is liquidy then the gases will escape resulting in a nonexplosive eruption. If the magma is high in silica and water then it will be thick If the magma is low or has no silica or water then it will be liquidy. - Negehna 6th Grade
