Generally, these rocks (granite and rhyolite) are light in color, and their density is relatively low. The feldspar predominates in intermediate rocks, which have a slight silica content. Magma ...

While the viscosity of any fluid is always relative to what it’s being compared to, we’re specifically discussing some of the newer “ultra-low” viscosity oils — like 0w-16 or 0w-8 ...

Lava flows are masses of magma that pour onto the Earth's surface ... called alkaline lava, has an extremely low viscosity, making it almost as fluid as water. Alkaline lava has a melting ...

A recent study from scientists at NASA and the University of Arizona found that a layer of low-viscosity goo sits between ... After all, how did the magma-like layer get there in the first place?

The mélange rises as diapirs into the overlying hot mantle wedge due to its buoyancy and low ... viscosity, which then melts along with the surrounding mantle rocks and eventually forms the arc ...
